x= -2,-3

Step-by-step explanation:

Answer:

28 in

Step-by-step explanation:

6+2= 8 so therefore the length is eight.

To find perimeter, add up all the sides of the rectangle so 6+6+8+8=28

Final answer:

The perimeter of the rectangle is calculated using its length and width. With a width of 6 inches and 2 inches added to determine the length, the perimeter is found to be 28 inches.

Explanation:

To determine the perimeter of the rectangle, we first have to calculate both the width and the length. The width is given as 6 inches. The problem states that the length is 2 inches more than its width, which means the length is 6 inches + 2 inches = 8 inches.

The formula to compute the perimeter (P) of a rectangle is P = 2 * (length + width). Substituting our values, we get P = 2 * (8 inches + 6 inches) = 2 * 14 inches = 28 inches. Therefore, the perimeter of the rectangle is 28 inches.

Answer:

24 x + 10 y >= 200

Step-by-step explanation:

as x represents centerpiece and y represent  bouquet and total number of roses should be atleast 200 which means we can use roses more than 200 but not less than 200,  the equation will be:

24 x + 10 y >= 200

Answer:

[tex]24x+10y\geq 200[/tex]

Step-by-step explanation:

Givens:

According to the problem, we can define the number of roses per a centerpiece: [tex]24x[/tex]

The number of roses per bouquet: [tex]10y[/tex]

So, the problem restricts the amount of roses, at least 200, that means, 200 or more than 200 roses. Therefore the expression that represent the amount of roses would be:

[tex]24x+10y\geq 200[/tex]

As you can observe, the inequality includes the 200 roses restriction, and the amount of roses per centerpieces and per bouquet.

Slower bike = X

Faster bike = X+9

They both ride for 2 hours, now you have 2x and 2(x+9)

The sum of the two cyclists is 66 miles:

2x +2(x+9) = 66

Use distributive property:

2x + 2x+18 = 66

Simplify:

4x +18 = 66

Subtract 18 from both sides:

4x = 48

Divide both sides by 4:

x = 48/4

x = 12

The slower bike was going 12 mi/h

The faster bike was 12+9 = 21 mi/h.

A power of 10 is the number 10 multiplied by itself by the number of times indicated by the exponent. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.

1/100,000,000 expressed as a power of 10 is 10-8, reflecting the movement of the decimal point 8 times to the left.

The question asks for the expression of 1/100,000,000 as a power of 10. To find the answer, we need to realize that this fraction is the same as moving the decimal point 8 places to the left from 1, making it 0.00000001. This operation is equivalent to the negative power of 10, because you're making the number smaller (or dividing). Remembering that the exponent represents how many times we move the decimal place, we can express 1/100,000,000 as 10-8.

If the dices have equal probability, that means each number has a 1/6 chance of getting picked because there are 6 sides to a dice with 6 different numbers.

There are a total of 36 combinations, because 6 * 6 is 36.

It would be impossible to have a sum of 1, as the lowest number on both dice is 1. 1 + 1 = 2. Therefore there is a 0/36 probability of getting a sum of 1.

Answer:  F) (x, y) → (x - 6, y  + 2)

Step-by-step explanation:

6 units to the left means subtract 6 from the x-value --> x - 6

2 units up means add 2 to the y-value --> y + 2

As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.

In order to solve for x we can set up the proportion between the horizontal and vertical sides:

[tex]28\div 11.2 = 27+x \div x[/tex]

Solving this proportion for x implies [tex]x=18[/tex]

Now you can solve for m and p using the pythagorean theorem, because both triangles are right:

[tex]m = \sqrt{18^2+11.2^2} =21.2[/tex]

Then, we know that the hypothenuse of the big triangle is m+p, so we have

[tex]m+p=\sqrt{(18+27)^2+28^2} = 53[/tex]

which implies

[tex]p = 53-p = 53-21.2=31.8[/tex]

The ratio of the given to similar triangles is 0.4. value of the x, m, and p is 18, 21.2, and 31.8.

Similar triangles are triangles whose corresponding sides are in ratio, while the corresponding angles are of equal measure.

As the two sides of the triangles are already given, therefore, the ratio of these two triangles are,

[tex]\dfrac{11.2}{28} = \dfrac{2}{5}[/tex]

As we already know the ratio of the two triangles, therefore,

[tex]\dfrac{x}{27+x} = \dfrac{2}{5}\\\\5x = 54 + 2x\\\\5x-2x = 54\\\\3x = 54\\\\x = 18[/tex]

Hence, the value of x is 18.

As the given triangle is a right-angled triangle, therefore, we can use the Pythagorean theorem to find the value of m,

[tex](Hypotenuse)^2 = (Perpendicular)^2+(Base)^2\\\\m^2 = x^2 + (11.2)^2\\\\m^2 = 18^2 + 11.2^2\\\\m^2 = 324+125.44\\\\m^2 = 449.44\\\\m = 21.2[/tex]

Thus, the value of side m is 21.2 units.

The value of m and p can be found using the same ratio, we already have for similar triangles,

[tex]\dfrac{m}{m+p} = \dfrac{2}{5}\\\\\dfrac{21.2}{21.2+p} = \dfrac{2}{5}\\\\106= 42.4 + 2p\\\\p = 31.8[/tex]

Thus, the value of the x, m, and p is 18, 21.2, and 31.8.

Answer:

y = x²/4 + x/2 + 21/4 ⇒ -9 ≤ x ≤ 7

Step-by-step explanation:

∵ x = 2t - 1

∴ 2t = x + 1 ⇒ t = (x + 1)/2

∵ y = t² + 5

∴ y = [(x + 1)/2]² + 5 = (x² + 2x + 1)/4 + 5

  y = x²/4 + x/2 + 1/4 + 5 = x²/4 + x/2 + 21/4

∵ -4 ≤ t ≤ 4

Both rectangles have the same dimensions and shape. P'Q'R'S' is a translated image of PQRS, shifted 3 units right and 3 units up. They are congruent but not identical due to their position.

Step-by-step comparison of rectangles PQRS and P'Q'R'S':

1. Original coordinates:

Assume specific coordinates for the vertices of rectangle PQRS. For example, let P = (1, 2), Q = (5, 2), R = (5, 6), and S = (1, 6).

2. Translation:

A translation moves every point in the shape the same distance and in the same direction. Since Rashid translated rectangle 3 units up and 3 units to the right, add 3 to x-coordinate and 3 to y-coordinate of each point in PQRS to find corresponding points in P'Q'R'S'.

3. New coordinates:

P' = (1 + 3, 2 + 3) = (4, 5)

Q' = (5 + 3, 2 + 3) = (8, 5)

R' = (5 + 3, 6 + 3) = (8, 9)

S' = (1 + 3, 6 + 3) = (4, 9)

4. Comparison:

Shape:

Both rectangles PQRS and P'Q'R'S' are rectangles because a translation preserves the shape of the original figure.

Size:

They have the same dimensions (length and width) as the translation only shifts the position without altering the size.

Orientation:

They maintain the same orientation relative to the axes, meaning their sides remain parallel and perpendicular to the x and y axes.

Position:

The key difference lies in their position. P'Q'R'S' is located 3 units to the right and 3 units above PQRS.

5. Rectangles PQRS and P'Q'R'S' are congruent (same size and shape) but not identical (different positions).

P'Q'R'S' is a translated image of PQRS, moved 3 units to the right and 3 units up.

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - [tex]\frac{1}{4}[/tex], hence

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute (12, 2) into the partial equation

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - [tex]\frac{1}{4}[/tex] x + 5 ← equation of line

Answer:

Ben had biked 8 miles

Step-by-step explanation:

You would need to take 12 and divide it by three . That would make 4. After that you would take 4 and multiply it by 2 since he rode 2/3 miles of 12.  Then you would end up with 8.

Final answer:

Ben has biked 8 miles of the 12 miles he wants to, as he has completed 2/3 of his intended distance.

Explanation:

To calculate the number of miles Ben has biked, we simply need to multiply the total distance he wants to bike by the fraction of the trip he has completed. Ben wants to bike 12 miles, and he has biked 2/3 of that distance. Multiplying these together gives us 2/3 * 12 = 8 miles. Therefore, Ben has biked 8 miles so far.

It would go between 7.32 and 7.37

Answer:

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

b = 3.1

Answer:

Equation that can be used to find length of the base is b + 12.6 = 15.7  and the length of the base we get from this equation is 3.1 cm

Step-by-step explanation:

Given:

Length of the equal side of the Isosceles Triangle = a

Length of the base of the triangle = b

Equal sides are longer than base of the triangle.

Perimeter of the triangle = 15.7 cm

Equation representing given information = 2a + b = 15.7

To find: Equation that represent or can be used to find length of the base if longer side = 6.3 cm

Given Equation is the Equation representing the perimeter of the isosceles triangle.

Longer side  = 6.3 cm = Length of the Equal Sides of the triangle.

So, a = 6.3 cm

Now,

2 × 6.3 + b = 15.7

b + 12.6 = 15.7

b = 15.7 - 12.6

b = 3.1 cm

Therefore, Equation that can be used to find length of the base is b + 12.6 = 15.7  and the length of the base we get from this equation is 3.1 cm

Given a quadratic equation [tex]ax^2+bx+c=0[/tex]

The discriminant is defined as

[tex]\Delta=b^2-4ac[/tex]

In your case, the equation is defined by the coefficients

[tex]a=3,b=0,c=-10[/tex]

So, the discriminant is

[tex]\Delta=0^2-4\cdot 3\cdot (-10) = 120[/tex]

The discriminant is involved in the solving formula as follows:

[tex]x_{1,2} = \dfrac{-b\pm\sqrt{\Delta}}{2a}[/tex]

Which implies that:

In your case, since the discriminant is positive, you have two distinct solutions. Since 120 is not a perfect square, however, you will not get rid of the square root, so you will have two distinct irrational solutions.

The equation 3x² - 10 = 0 has a discriminant of 120, which is greater than zero. This means that there are two distinct real roots for this equation.

To describe the roots of the equation 3x² - 10 = 0 using the discriminant, we must first understand that the discriminant (d) of a quadratic equation of the form ax² + bx + c = 0 is given by b2 - 4ac. For our equation, a = 3, b = 0, and c = -10, so the discriminant
would be:
= (0)2 - 4(3)(-10) = 0 + 120 = 120

Since  > 0, this indicates that there are two distinct real roots. When the discriminant is greater than zero, the quadratic equation has two real solutions. Therefore, in this case, 3x2 - 10 = 0 has two real roots, corresponding to the x-values where the parabola intersects the x-axis.
