Answer:

(7,-2)

Step-by-step explanation:

3x+2y=17

-2x-y=-12

Multiply the second equation by 2 so we can eliminate y

2( -2x-y=-12)   becomes -4x-2y = -24

Add this to the first equation

3x+2y=17

-4x-2y=-24

----------------

-x = -7

Multiply each side by -1

x = 7

Substitute back into the first equation to find y

3(7) +2y = 17

21 +2y = 17

Subtract 21 from each side

21-21 +2y = 17-21

2y = -4

Divide each side by 2

2y/2 = -4/2

y =-2

The correct comparison for the expressions 2b and b+g is 2b > b+g.

Let's analyze the expressions:

Comparing 2b and b+g, the correct statement is A. 2b > b+g as having more green balls than blue balls implies the total green balls are more, making the expression 2b greater than b+g.

Based on these cases, the only condition that aligns with g > b is when [tex]\(2b < b + g.[/tex]

Thus, the correct answer is: B. 2b < b + g.

To find which statement is correct, let's consider the relationship between the number of green balls (g) and the number of blue balls (b). Since the bag has more green balls than blue balls, it means that g > b.

To compare the expressions 2b and b + g, let's examine their relationship under the condition g > b

When 2b > b + g

Rearranging 2b > b + g, we get:

b > g.

This contradicts the condition g > b.

So, this case is not possible.

Case 2: When 2b < b + g :

Rearranging 2b < b + g, we get:

b < g,

which aligns with the given condition g > b.

Hence, this condition is possible.

When 2b = b + g

Rearranging 2b = b + g, we get: [tex]\[b = g.\][/tex]

This condition contradicts the original requirement g > b, so this case is also not possible.

The only condition that aligns with g > b is when [tex]\(2b < b + g.[/tex] Thus, the correct answer is: B. 2b < b + g.

Question : A bag has more green balls than blue balls, and there is at least one blue ball. Let b represent the number of blue balls and let g represent the number of green balls. Let's compare the expressions 2b and b+g. Which statement is correct?

A. 2b>b+g

B. 2b C. 2b=b+g

Answer:

[tex]y=- 4x + 4[/tex]

Step-by-step explanation:

The slope formula for a straight line is:

[tex]y=mx+b[/tex]

Where, 'm' is the slope and 'b' is the y-intercept.

To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).

To find the slope, we use the following formula:

[tex]m = \frac{y1-y0}{x1-x0} = \frac{0-12}{1-(-2)} = -4 [/tex]

Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:

[tex]y - 12 = -4(x+2) ⇒ y = -4x-8 + 12 ⇒ y=- 4x + 4[/tex]

The equation of the line using the slope-intercept form is:

[tex]y=- 4x + 4[/tex]

[tex]P=0.735[/tex]

Step-by-step explanation:

Call A to the event in which Nathan is allergic to penicillin

So

[tex]P (A) = 0.75[/tex]

[tex]P (A') = 1-P (A) = 0.25[/tex]

Call B the event in which the skin test predicts correctly.

So:

[tex]P (B) = 0.98\\P (B ') = 1-P (B) = 0.02[/tex]

We look for the probability that Nathan is allergic to penicillin and the test predicts it.

This is [tex]P (A\ and\ B)[/tex].

[tex]P (A\ and\ B) = P (A)*P (B)\\\\P (A\ and\ B) = 0.75 * 0.98\\\\P (A\ and\ B) = 0.735[/tex]

Answer:

k = 3.

Step-by-step explanation:

If the 2 roots are A and B we have the relations:

AB = 8/k and A+B = -14/k.

We are given that A = 6B so

6B^2 = 8/k

B^2 = 8/6k = 4/3k

B = 2 /√(3k) ......(1)

Now A + B = -14/k so

6B + B = 7B = -14/k

B = -2/k..........(2)

Eliminating B from equations (1) and (2):

2 /√(3k) = -2/k

Cross multiply:

2k = -2√(3k)

Squaring both sides:

4k^2 = 4 * 3k

4k^2 = 12k

k^2 = 3k

k = 3.

To find the value of k, we first define the roots as p and 6p. We then use the properties of the sum and product of roots in a quadratic equation to form two equations. We can solve these equations to get the value of k.

The given quadratic equation is kx2 + 14x + 8 = 0. We are looking for the value of k for which one root of the equation is six times the other. Let's denote the roots by p and 6p (since one is 6 times the other).

For a quadratic equation ax2 + bx + c = 0, the sum of the roots is given by -b/a and the product of the roots is c/a. In this case, -b/a or -14/k is equal to the sum of the roots (p + 6p). The product of the roots, c/a or 8/k, is equal to p*6p.

From the sum of the roots equation, we can determine p = -14/7k and by substitifying p in the other equation we can solve for k.

Answer:

172 degrees

Step-by-step explanation:

The complement of an angle, when added to that angle is equal to 90, so do x + 82 = 90

x = 8

The supplement of a an angle when added to that angle is equal to 180 so do

y + 8 = 180

y = 172

Applying the definition of supplementary angles and complementary angles, if angle A is 82 degrees, the supplement of the complement of angle A is: 172 degrees.

Recall:

Given that Angle A equals 82 degrees.

Thus:

The supplement of 8 degrees will be: 180 - 8 = 172 degrees.

Therefore, applying the definition of supplementary angles and complementary angles, if angle A is 82 degrees, the supplement of the complement of angle A is: 172 degrees.

Step-by-step explanation:

Answer:

(-3, 1), 5

Step-by-step explanation:

x² + y² + 6x - 2y - 15 = 0

Rearrange:

x² + 6x + y² - 2y = 15

Complete the square:

x² + 6x + 9 + y² - 2y + 1 = 15 + 9 + 1

(x + 3)² + (y - 1)² = 25

Therefore, the center is (-3, 1) and the radius is 5.

The center of the circle is (-3, 1), and the radius is 5.

To find the center and radius of the circle described by the equation[tex]x^2 + y^2 + 6x - 2y - 15 = 0,[/tex] we'll first rewrite the equation in standard form, which has the general form:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where (h, k) represents the center of the circle, and r represents the radius.

Let's complete the square to rewrite the given equation in standard form:

[tex]x^2 + 6x + y^2 - 2y = 15[/tex]  

Now, we'll complete the square for both the x and y terms.

To complete the square for the x terms, we add and subtract [tex](6/2)^2 = 9:x^2 + 6x + 9 + y^2 - 2y = 15 + 9[/tex]

Now, complete the square for the y terms by adding and subtracting (-2/2)^2 = 1:

[tex]x^2 + 6x + 9 + y^2 - 2y + 1 = 15 + 9 + 1[/tex]

Now, we have:

[tex](x^2 + 6x + 9) + (y^2 - 2y + 1) = 25[/tex]

Next, we can rewrite this as two perfect square trinomials:

[tex](x + 3)^2 + (y - 1)^2 = 25[/tex]

Now, the equation is in standard form. Comparing it to the standard form, we can see that:

h = -3 (opposite sign in the equation)

k = 1 (opposite sign in the equation)

[tex]r^2 = 25[/tex] (radius squared)

To find the radius (r), take the square root of 25:

r = √25 = 5.

Answer: 180 ft³

Step-by-step explanation:

You can calculate the volume of a right rectangular prism with this formula:

[tex]V=lwh[/tex]

Where "l" is the length and "w" is the width.

You know that the height of that this right rectangular prism is 15 feet, its length is 24 inches and its width is 6 feet.

Then, you need to make the conversion from 24 inches to feet (1 feet=12 inches):

[tex]l=(24in)(\frac{1ft}{12in})= 2ft[/tex]

Then, susbtituting values, you get:

[tex]V=(2ft)(6ft)(15ft)=180ft^3[/tex]

For this case we have by definition, that the Greatest Common Factor or GFC, of two or more whole numbers is the largest integer that divides them without leaving a residue.

The sum of the series 14+20+26+...+1244 is 129,045.

The question is to find the sum of the sequence 14+20+26+...+1244. This is an arithmetic series where the common difference (d) is 6, since each term is 6 more than the previous term. The first term (a1) is 14.

To find the sum of the series, we need to determine the number of terms (n). The nth term of an arithmetic series is given by an = a1 + (n-1)d. We will set an to 1244, the last term, and solve for n:

1244 = 14 + (n-1) × 6

n = (1244 - 14)/6 + 1

n = 205

Now that we have the number of terms, we can use the sum formula for an arithmetic series which is S = n/2  × (a1 + an). Thus:

S = 205/2 × (14 + 1244)

S = 102.5 × 1258

S = 129,045

So, the sum of the series 14+20+26+...+1244 is 129,045.

Answer:

Quadrant I

Step-by-step explanation:

To find in which quadrant an angle is, you have to locate it between 0 and 360.

Since your angle is larger than 360 degrees, we subtract 360 degrees from it.... to get 27 degrees.

27 degrees and 387 degrees lie on the same spot, since they are exactly one turn around from each other.

Now, angles between 0 degrees and 90 degrees are in quadrant I

angles between 90 and 180 degrees are in quadrant II

Angles between 180 and 270 degrees are in quadrant III

Angles between 270 and 360 degrees are in quadrant IV

So, an angle of 27 degrees would land in Quadrant I.... so is 27 + 360x, where x is any integer representing a number of turns.

The answer is:

The terminal side of the angle 387° lies at the Quadrant I.

We know that there are four quadrants on the plane, those quadrants goes from 0° to 360°, however, since the quadrant is going only from 0° to 360°, if we want to know where an angle greater than 360° is located, we need to take only the excess, so:

We are asked to find where the angle 387° is located, we can write the angle by the following way:

[tex]387\°=360\°+27\°\\[/tex]

So, we have that there are 27° more than 360°, if we want to find where the 367° we only need to locate where the excess (27°) angle is located.

Also, we know that:

Quadrant I: 0° to 90°

Quadrant II: 90° to 180°

Quadrant III: 180° to 270°

Quadrant IV: 270° to 360°

We have that 27° is between 0° and 90°, so, it's located on the first quadrant.

Hence, we have that the angle 367° is located at the Quadrant I.

The function is A = 10√r

Step-by-step explanation:

* Lets explain the meaning of direct variation

- The direct variation is a mathematical relationship between two

  variables that can be expressed by an equation in which one

  variable is equal to a constant times the other

- If Y is in direct variation with x (y ∝ x), then y = kx, where k is the

 constant of variation

* Now lets solve the problem

# A is varies directly with the square root of r

- Change the statement above to a mathematical relation

∴ A ∝ √r

- Chang the relation to a function by using a constant k

∴ A = k√r

- To find the value of the constant of variation k substitute A and r

 by the given values

∵ r = 16 when A = 40

∵ A = k√r

∴ 40 = k√16 ⇒ simplify the square root

∴ 40 = 4k ⇒ divide both sides by 4 to find the value of k

∴ 10 = k

- The value of the constant of variation is 10

∴ The function describing the relationship of A and r is A = 10√r

Answer:

A = 10[tex]\sqrt{r}[/tex]

Step-by-step explanation:

Given A varies directly with the square root of r then the equation relating them is

A = k[tex]\sqrt{r}[/tex] ← k is the constant of variation

To find k use the condition r = 16 , A = 40

k = [tex]\frac{A}{\sqrt{r} }[/tex] = [tex]\frac{40}{\sqrt{16} }[/tex] = [tex]\frac{40}{4}[/tex] = 10

A = 10[tex]\sqrt{r}[/tex] ← equation of variation

GIVE ME BRAINLIEST PLEASE !!! :)

Answer:

21, 23 and -21, 23

Step-by-step explanation:

The difference between two consecutive odd numbers is 2.

Let the smaller number be x. Then, the larger number is x + 2.

Now add their squares and set it equal to 970. Then  solve for x.

smaller number: x

larger number: x + 2

sum of the squares of the two numbers: x^2 + (x + 2)^2

equation: x^2 + (x + 2)^2 = 970

Solution of the equation:

x^2 + (x + 2)^2 = 970

Expand the square of the binomial:

x^2 + x^2 + 4x + 4 = 970

Combine like terms on the left side:

2x^2 + 4x + 4 = 970

Subtract 970 from both sides:

2x^2 + 4x - 966 = 0

Divide both sides by 2:

x^2 + 2x - 483 = 0

Now we need to factor the binomial. We need two number whose sum is 2 and whose product is -483. Look at 483. It is not divisible by 2, but it is divisible by 3.

483/3 = 161

161 is divisible by 7.

161/7 = 23

23 is prime, so the prime factorization of 483 is

483 = 3 * 7 * 23

Notice that 3 * 7 = 21, so

483 = 21 * 23

Use -21 and 23:

-21 + 23 = 2

-21 * 23 = -483

x^2 + 2x - 483 factors into (x - 21)(x + 23)

Now we continue solving the equation.

x^2 + 2x - 483 = 0

(x - 21)(x + 23) = 0

x - 21 = 0 or x + 23 = 0

x = 21 or x = -23

We let x equal the smaller of the two integers, so now we add 2 to find the second integer.

x = 21; x + 2 = 23

x = -23; x + 2 = -21

There are two sets of consecutive odd numbers that satisfy this problem.

21, 23

-23, -21

The problem did not state positive or negative consecutive odd numbers, so both solutions are valid.
