1 answer:

6 0

To find the value of y in the given equation, substitute the given value of x to the equation.

y = 4x + 2x² -x³

Substitute 2 for all x's.

y = 4(2) + 2(2²) - 2³ = 8

Therefore, the value of y is 8.

Answer:

The average speed is $\frac{3}{35}\frac{ft}{min}$

Step-by-step explanation:

we know that

To find out the average speed divide the distance by the time

Let

s -----> average speed

d -----> the distance in feet

t ----> the time in minutes

$s=\frac{d}{t}$

we have

$d=6\ ft$

$t=70\ min$

substitute

$s=\frac{6}{70}\frac{ft}{min}$

Simplify

$s=\frac{3}{35}\frac{ft}{min}$
