You have the intercepts and x-coordinate of the vertex correct. There appears to be a math error in the calculation of the y-value of the vertex.
f(7/8) = (4*7/8 -7)*(7/8) -15 = -49/16 -15 = -289/16 = -18.0625
Answer: A
Step-by-step explanation:
Answer:
The answer should be 6
Step-by-step explanation:
My short answer to this is no.
I don't see how the text got 0. I'm going to get 6 as well
If x = 4 then
abs(4 - 7) + 3 = ??
abs( - 3) + 3 =
3 + 3 = 6
You are correct.
Answer:
The x intercept is (-5,0)
The y intercept is (0,-3)
Step-by-step explanation:
To find the x intercept we set y=0 and solve for x
3x+5y = -15
3x+0 = -15
3x = -15
Divide by 3
3x/3 = -15/3
x = -5
The x intercept is (-5,0)
To find the x intercept we set x=0 and solve for y
3x+5y = -15
0+5y = -15
5y = -15
Divide by 5
5y/5 = -15/5
y = -3
The y intercept is (0,-3)
-5 is for f(x)=x+5
4 is for g(x)=x-4
Hope this helps!!
