Solve 5+7√x+6=26 for x.

225/49

Step-by-step explanation:

5+7√x+6=26

7√x+11=26

Step 1: Add -11 to both sides.

7√x+11+−11=26+−11

7√x=15

Step 2: Divide both sides by 7.

7√x

7

=

15

7

√x=

15

Step 3: Solve Square Root.

√x=

15

7

x=(

7

)2(Square both sides)

x=

225/49

(Works in original equation)

x=225/49

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
