Answer:

=8x^3+x^2+3

Step-by-step explanation:

Let's simplify step-by-step.

1+7x^3−x^2+x^3+2+2x^2

=1+7x^3+−x^2+x^3+2+2x^2

Combine Like Terms:

=1+7x^3+−x^2+x^3+2+2x^2

=(7x^3+x^3)+(−x^2+2x^2)+(1+2)

=8x^3+x^2+3

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?

bezimeni [28]

Answer:

t = - 24

Step-by-step explanation:

Given t varies inversely as a then the equation relating them is

t = $\frac{k}{a}$ ← k is the constant of variation

To find k use the condition t = 2 when a = - 4

2 = $\frac{k}{-4}$ ( multiply both sides by - 4 )

- 8 = k

t = $\frac{-8}{a}$ ← equation of variation

When a = $\frac{1}{3}$ , then

t = $\frac{-8}{\frac{1}{3} }$ = - 24
