Answer:
x=2
Step-by-step explanation:
8x- 1/3 y = 16
when y = 0
8x = 16
x = 2
x-intercept (2,0)
First number = x
Consecutive number = x+1
"squares differ by 31" means to square both numbers and subtract them:
(x+1)^2 - (x)^2 = 31
x^2+2x+1 - x^2 = 31
2x+1 = 31
2x = 30
x = 15 (first number)
x+1 = 15+1 = 16 (consecutive number)

We have
We can add 46 to both sides so the -21 becomes a +25. by doing that, we get
This can be wrote as
We solve the square root and get
(The +- is a plus minus sign.) Subtract five on both sides to get
The answer is
C.
