Answer:
x = -1
Step-by-step explanation:
First, we can translate this statement to the equation
Subtracting 4x from both sides gives us a quadratic equation:
From here, we can factor the expression on the right to give us the equation's two solutions. The factored form will look like
We need a + b = -4 and ab = -5, and picking a = 1 and b = -5 do the job there. Our expression factors then to (x + 1)(x - 5), giving us the equation
And the solutions x = -1 and x = 5. Since we're only looking for the negative solution, x = -1 is the one we want.
If x is 2, you substitute all the x in the expression for the number 2:
2 - 2 - 1 + 12
-1 + 12

When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:
a. y=8x+13
