I need this for a test

x=16

Step-by-step explanation:

Remove the radical by raising each side to the index of the radical.

x = 16

Step-by-step explanation:

∛9 + x = 15

Divide both sides by 3

√9 + x = 5

The squareroot of 9 + x has to be 5

√9 + x² = 5²

9 + x = 25

Subtract both sides by 9

x = 16

Now we check if our answer is correct

∛9 + x = 15

∛9 + (16) = 15

∛25 = 15

3 × 5 = 15

15 = 15

Its correct!

Hope I helped!

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
