P(-3)=x^3+5; evaluate P(-3)

1 answer:

5 0

You are given P(x) = x^3 + 5, not P(-3). You are to evaluate the function at x=-3.

The function is P(x)=x^3+5. Let's now replace x with (-3):

P(-3) = (-3)^3 + 5 = -27 + 5 = -22 (answer)

Find the slope of the line described by the equation. 4y = 152 − 19x

Softa [21]

Answer: - 19/4

Step-by-step explanation:

To find the slope , all we need to do is to write the equation in the form y = mx + c , where m is the slope and c is the y - intercept.

That means we need to make y the subject of the formula in the equation.

4y = 152 - 19x

Divide through by 4

y = 152/4 - 19x/4

y = 38 - 19x/4

Therefore the slope is -19/4
