Answer:
x>7
Step-by-step explanation:
Add 2 to both sides
1. Use Difference of squares: a^2-b^2=(a+b)(a-b)
(x+k)(x-k)=0
2. Solve for x and k
x=+-k
k=+-x
Answer:
see below
Step-by-step explanation:
y = 10x - 32
To find the x intercept set y =0 and solve for x
0 = 10x -32
Add 32 to each side
32 = 10x
Divide by 10
32/10=10x/10
3.2 = x
To find the y intercept set x =0 and solve for t
y = 10*0 -32
y= -32
