Step-by-step explanation:
160 = x + 4x + x + 10
160 = 6x + 10
6x = 150
x = 25
We have the total length of VW and we know that C lies somewhere on that line.
Therefore:
VC + CW = VW
z+13+z+8 = 61
2z+21=61
2z=61-21
2z=40
z=40/2
z=20
Answer:
Step-by-step explanation:
There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is
We have the function
From this function, we can find that
We can plug in our know values into the formula to get
Then we can plug in our x-value to find the y-value of the vertex
This means that the vertex would be
I believe you have to find y by plugging in x.
6(-2) = 7 - 4y
-7 -7
-12 -7 = -4y
-19
/-4 /-4
4.75 = y
y = 4.75
6(-1) = 7 -4y
-7 -7
-13 = -4y
/-4 /-4
3.25 = y
y = 3.25
6(0) = 7 - 4y
-7 -7
-7 = -4y
/-4 /-4
1.75 = y
y = 1.75
