Answer:

(6, -3)

Step-by-step explanation:

I will solve this system using elimination.

[tex][tex]\left \{ {{-x+2y=-12} \atop {2x+3y=3}} \right.[/tex][/tex]

I will multiply [tex]-x+2y=-12[/tex] by 2 so that -x becomes -2x.

2(-x + 2y = -12)

Distribute.

-2x + 4y = -24

Now subtract this from the other equation.

2x + 3y = 3

-2x + 4y = -24

        7y  =  -21

Divide both sides by 7.

y = -3

Now that we have the value of y, plug it into the original equation.

-x + 2(-3) = -12

Simplify.

-x - 6 = -12

Add 6 to both sides.

-x = -6

Divide both sides by -1.

x = 6

(6, -3)

Answer: log₂[tex](\frac{h(n)}{6})[/tex] + 1 = n

Step-by-step explanation:

h(n) = 6 * 2ⁿ⁻¹

÷6     ÷6          

[tex]\frac{h(n)}{6}[/tex] = 2ⁿ⁻¹

log₂[tex](\frac{h(n)}{6})[/tex] =  log₂(2ⁿ⁻¹)  →→log₂2 cancels out

log₂[tex](\frac{h(n)}{6})[/tex] = n - 1

log₂[tex](\frac{h(n)}{6})+1[/tex] = n

Answer:

74.30

Step-by-step explanation:

Let s = entry price for a student

Let t = entry price for a teacher

4s +5t = 95

6s+10t = 173

I will use elimination to solve this problem.

Multiply the first equation by -2

-2(4s +5t) = -2*95

Distribute

-8s - 10t = -190

Add this equation to the second equation to eliminate t

-8s - 10t = -190

6s+10t = 173

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

-2s = -17

Divide by -2

-2s/-2 = -17/-2

s = 8.50

Now we need to find t

4s +5t = 95

Substitute s=8.50

4(8.50) +5(t) = 95

34 +5t = 95

Subtract 34 from each side

34-34 +5t = 95-34

5t = 61

Divide by 5

5t/5 = 61/5

t = 12.20

We want to find the cost for 3 students and 4 teachers

3s+4t

3(8.50) + 4(12.20)

25.50 + 48.80

74.30

Answer:

12

Step-by-step explanation:

Orange juice: $2.20 per bottle.

10 bottles of orange juice cost 10 * $2.20 = $22.00.

We subtract the cost of the 10 bottles of orange juice from the amount of money he has to find out the amount he will have left for bottles of apple juice.

$50.80 - $22.00 = $28.80

After buying the 10 bottles of orange juice, he has $28.80 left.

We divide the money he has left for apple juice bottles by the price of one apple juice bottle to find out the number of apple juice bottles he can buy.

$28.80/$2.40 = 12

He can buy 12 bottles of apple juice.

This is distributive property and to do distributive property, you distribute what is outside of the parenthesis to the numbers inside the parenthesis.

Answer:

x= 7

Step-by-step explanation:

2x^2=98

\frac{2x^2}{2}=\frac{98}{2}

x^2=49

7^2=49

Final answer:

The solutions to the equation 2x^2 = 98 are x = 7 and x = -7, obtained by isolating the x^2 term and taking the square root of both sides.

Explanation:

To solve the equation 2x^2 = 98, we need to convert it into a standard quadratic equation by bringing the terms to one side of the equals sign, setting it equal to zero:

2x^2 - 98 = 0

Now, we will proceed to solve the quadratic equation. In this simple case, we can find the solutions by factoring or by taking square roots. First, we move the constant to the other side:

2x^2 = 98

Divide both sides by 2 to isolate the x^2 term:

x^2 = 49

To find x, we take the square root of both sides. Do not forget to consider both the positive and negative roots:

x = ±√49

x = ± 7

So the solutions to the equation 2x^2 = 98 are x = 7 and x = -7.

y=the amount of money in the checking account

x=number of months

y=200-20x

Answer:

9x - 8

Step-by-step explanation:

the perimeter is the sum of the sides, hence

perimeter = 5x - 2 + 3x + 4 + x - 10 ( collect like terms )

                = 9x - 8 ← polynomial of degree 1

Divide both sides by 2

3x + 1 = 11/2

Subtract 1 from both sides

3x = 11/2 - 1

Simplify 11/2 - 1 to 9/2

3x = 9/2

Divide both sides by 3

x = 9/2/3

Simplify 9/2/3 to 9/2 × 3

x = 9/2 × 3

Simplify 2 × 3 to 6

x = 9/6

Simplify 9/6 to 3/2

x = 3/2

Answer:

Difference of cubes polynomial identity prove that 117 =125-8

Step-by-step explanation:

Difference of cubes:- A polynomial in the form of [tex]a^3 -b^3[/tex] is called  the difference of cubes.

The formula for difference of cubes is;

[tex]a^3 -b^3 = (a-b)(a^2+b^2+ab)[/tex]

To prove: 117 = 125 - 8

Take RHS

[tex]125-8 = 5^3 -2^3[/tex]

Apply difference of cubes;

[tex]5^3-2^3 = (5-2)(5^2+2^2+5\cdot 2)[/tex]

                     =[tex]3(25+4+10) = 3(39) = 117[/tex] = LHS       hence proved!

Therefore, difference of cubes polynomial identity will prove that 117 = 125-8

The first attached graph showing the plotted point (0, 3) represents Ramon's initial step.

Step-by-step explanation:

We are given that Ramon is graphing the function f(x) = 3(4)x and that he begins by plotting the initial value.

So if we will input 1 for the value of x and then evaluate the plot point.

Therefore, we will get the point (0, 3) as the answer for this initial step.

Also, the first attached graph here showing the plotted point (0, 3) represents Ramon's initial step.

Answer:

The graph that represent the initial step in the attached figure

Step-by-step explanation:

we have

[tex]f(x)=3(4^{x})[/tex]

we know that

The initial value is the value of the function when the value of x is equal to zero

so

For [tex]x=0[/tex]

substitute in the function

[tex]f(x)=3(4^{0})=3(1)=3[/tex]

therefore

The initial value is the point [tex](0,3)[/tex]

The hypotenuse of the ΔBAD is the side BD.

The longest side in a right angled triangle is called hypotenuse, it is the side which is opposite to 90° angle.

Step 1 : In the given cube, we should look at the face ABCD

Step 2 : Let us draw an imaginary line between the point B and D

Step 3 : Now the face ABCD is split into two triangles ΔBAD and ΔBCD respectively

Step 4 : The side opposite to the 90° angle of ΔBAD is BD

Hence the side BD is hypotenuse of ΔBAD.

Answer:

A. 179 sq. ft.

Step-by-step explanation:

Area of walkway + fountain: (3.14)11^2=379.94 ft^2

Area of fountain: (3.14)8^2=200.96 ft^2

Area of walkway : 379.94-200.96=178.98 ft^2 which is also rounded to 179ft^2

Answer:

If you use 3.14 as an approximation for PI, the answer will be A) 179 sq. feet.

Step-by-step explanation:

The process to determine the area of the sidewalk is computed by figuring the area of the outer circle (Diameter = 16' + 3' + 3') and subtracting the area of the fountain (Diameter = 16') from that.

Area of Circle = PI times Radius squared

Outer circle radius = (22 ft /2) = 11 ft

Area of outer circle (includes fountain area too) = 3.14 x 11 x 11 = 379.94 ~ 380

Inner circle radius = (16 ft / 2) = 8 ft

Area of Fountain = 3.14 x 8 x 8 = 200.96 ~ 201

Area of sidewalk =  380 - 201 =  179

Answer:

X=5 (Or (5,0))

Step-by-step explanation:

The Y intercept is when X=0

The X Intercept is when Y=0

Our equation is y=-4200x+21000

So let's rewrite it... First subtract 21,000 (Also, remember Y is 0)

0-21000=-4200x

-21000=-4200x

Now to get X alone, divide -21000 by -4200

This will give us 5=x, which is the same as x=5. There is your answer!

The slope means that the value decreases by -4,200 per year.

Here we have the linear equation:

y = -4,200x + 21,000

We know that this equation relates the value of something, y, after x years.

So a slope will tell us how many units does the value increase or decraeses each year.

Here the slope is -4,200, which means that the price decreases by -4,200 dollars each year.

It took Stephen 2.5 hours to run the entire 5-mile race.

To find out how long it took Stephen to run the entire race, we need to know how many 1/4 mile segments are present in a 5 mile race. We can do this by dividing the total distance by the distance ran in each segment. Since 1/4 mile is ran in 1/8 hour, we can divide 5 miles by 1/4 mile to find the total number of segments, which is 20. Multiplying 20 by 1/8 hour, we get the total time it took Stephen to run the race, which is 2.5 hours.
