This means that x is equal to -3 and y is equal to 8. For example, if you had f(x)=-3x-1 and plugged -3 into x, you would get the y-value of 8.
Hello,
A=(-4,2)
B=(3,-5)
AB≡y-2=(x+4)(-7)/7==>y=-x-2
Slope of the perpendicular: 1
y-2=(x-1)1==>y=x+1 is the equation of the perpendicular.
Intersection: y=x+1 and y=-x-2 ==>(-3/2,-1/2)=Q
|PQ|²=(-1/2-2)²+(1+3/2)²=25/2
|PQ|=5√2/2≈3.5355339059....
Answer:
y= -1/2x +1
Step-by-step explanation:
use the slope equation to find the slope, and the the point slope equation to solve for your equation
Answer:
-64
Step-by-step explanation:
If
y=x^2
and the x represents -8
Your answer will be -64
By saying that x=(-8) all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it y=(-8)^2
When you plug in negative 8 to the second power into the calculator your answer will be -64
I hope this helps king!
First, take half of the coefficient of 18x then square it.
18 / 2 = 9
9^2 = 81
So, D. 81 is the answer.
