Answer:
When x = -2 or when x = 7
Step-by-step explanation:
x+2 is a factor in the denominator. If x = -2, the factor becomes zero.
x-7 is a factor in the denominator. If x = 7, the factor becomes zero.
We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.
Answer:
x = 8
Step-by-step explanation:
2x + 46 = 7x + 6
Add -2x and -6 on both sides.
46 - 6 = 7x - 2x
40 = 5x
Divide 5 into both sides.
40/5 = x
8 = x

Shaquille is the fastest.
since it is perpendicular line you have to change thing signs of the equation.
x y
(-1,4)
replace the (-1) with x and (4) with y
y=1/2x+b
4=1/2(-1)+b
4=-1/2+b
4+1/2=b
9/2=b
therefore, the perpendicular line is y=1/2x+9/2
