Answer:

Step-by-step explanation:

To find the slope between the two given points, you can use the given formula for the slope between two points.

<h3>given</h3>

The points are (x1, y1) = (-3, 2) and (x2, y2) = (4, 2).

The formula is ...

slope = (y2 -y1)/(x2 -x1)

<h3>use the formula</h3>

Substituting the given values into the formula gives ...

slope = (2 -2)/(4 -(-3)) = 0/7 = 0

The slope of the line is zero.

Which equation is y = 2x2 – 8x + 9 rewritten in vertex form?

pishuonlain [190]

we have

$y=2x^{2} -8x+9$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-9=2x^{2} -8x$

Factor the leading coefficient

$y-9=2(x^{2} -4x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-9+8=2(x^{2} -4x+4)$

$y-1=2(x^{2} -4x+4)$

Rewrite as perfect squares

$y-1=2(x-2)^{2}$

$y=2(x-2)^{2} +1$ -----> equation in vertex form

therefore

the answer is the option C

$y=2(x-2)^{2} +1$

You borrow $18,000 to buy a new car. You will pay $3,240 in simple interest at the end of 6 years. What is the annual interest r

mixer [17]

Simple Interest, I = PRT/100

3240 = 18 000 * R * 6 /100

3240 = 180*R*6

3240 / (180*6) = R Use your calculator

3 = R

The annual interest rate is 3%.

Solve the following equation for N<br><br> 1/5 (N+3)+4=3/10 (2N-2)<br><br><br> n = ________

postnew [5]

Answer:

n = 13

Step-by-step explanation:

1/5(n + 3) + 4 = 3/10(2n - 2)

~Simplify both sides

1/5n + 3/5 + 4 = 3/5n - 3/5

~Combine like terms

1/5n + 23/5 = 3/5n - 3/5

~Subtract 23/5 to both sides

1/5n = 3/5n - 26/5

~Multiply 5 to both sides

n = 3n - 26

~Subtract 3n to both sides

-2n = -26

~Divide -2 to both sides

n = 13

Best of Luck!

Answer:

$(b^4)^2 = b^{8}$

Step-by-step explanation:

Given

$(b^4)^2$

Required

Simplify

In indices, we have:

$(a^m)^n = a^{m*n$

So:

$(b^4)^2 = b^{4*2}$

$(b^4)^2 = b^{8}$
