3x^2 - 72 = 0
3x^2 = 72
x^2 = 24
x = squareroot(24)
x = 4.9
Answer:
y = 5
Step-by-step explanation:
12^2 + y = 13^ 2
144 + y = 169
169 - 144 = 25
sqrt of 25 = 5
y = 5
True. A rational number is a number that can be put into a fraction and all real numbers can in the form of x/1
Answer:

Step-by-step explanation:
When solving inverse functions, switch the x and y's:
x=8y
Then solve for y: (divide 8 on both sides)
