Question

If x = 3, solve for y.
y = 5 x 2^x
y = [?]
Enter

Answer 1

Explanation:

Using the given formula, we can substitute x = 3 and solve for y:

y = 5 x 2^x

y = 5 x 2^3 (substitute x = 3)

y = 5 x 8

y = 40

Therefore, when x = 3, y = 40.

Answer 2

y = 40

Explanation:

Plug in 3 for x

`\bf{y=5*2^x}`

`\bf{y=5*2^3}`

Simplify

`\bf{y=5*8}`

Simplify

`\bf{y=40}`

Hence, y = 40
