40 = x - 20
move -20 to the other side
sign changes from -20 to +20
40+20= x-20+20
40+20=x
60=x
Answer:
b 60
Answer:
So a point is (-3,-5) and the vertex is (-4,-3)
Step-by-step explanation:
This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.
The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)
I will choice -3. This gives -2(-3+4)^2-3
f(-3)=-2(1)^2-3
f(-3)=-2-3
f(-3)=-5
So a point is (-3,-5) and the vertex is (-4,-3)
Answer:
1/5
Step-by-step explanation:
We can find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (3-2)/(4 - -1)
(3-2)/(4+1)
1/5
5600 can be simplified. Say you were to just take the two zeros off the end and you would have 56. Now divide 56 by 7 and you get 8. Add the zeros back to the 8 and your answer is 7 x 800. Hope this helps.
6a-2 (a-1) in simplest form is 4a+2.
