Answer: 5/3
(1/3)(5/1)=5/3
Answer:
B I believe.
Step-by-step explanation:
Answer:
1) the constant variation is B) -2
3) the equation of the line is C) y=2/3x+9
4) the equation of the line is D) y=2x-5
Answer:
y = -1/5 x + 7/5
Step-by-step explanation:
y = 5x + 4 so this line has slope = 5
Perpendicular line, slope is opposite and reciprocal so slope = -1/5
Passing thru (-3,2)
Equation
y - 2 = -1/5 (x + 3)
y - 2 = -1/5 x - 3/5
y = -1/5 x - 3/5 + 10/5
y = -1/5 x + 7/5
Answer:
B. g(x)=(x+7)^2-3
Step-by-step explanation:
Vertex form is F(x)= a(x-h)^2+k
a is the reflection
h and k are the vertex (x,y) = (h,k)
in this case there is no shrink or stretch (a)
if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7
If it translating up or down it is "K". In this case it is translated down so its -3.
If it was translated up or right then its positive. If it was translated down or left its negative.
After you figure out what h and k are then you just plug it in. h=-7, k=-3
so the answer in vertex form is, g(x)=(x+7)^2-3
