4(3w+5)-2w=70
10w+20=70
10w+20-20=70-20
10w=50
10w/10=50/10
w=5
Answer: Option D

Step-by-step explanation:
For a quadratic function of the form

The x coordinate of the vertice is:

In this case the function is:

So

The x coordinate of the vertice is:

The y coordinate of the vertice is:

The vertice is: (-3, -11)
The form e vertice for a quadratic equation is:

Where
the x coordinate of the vertice is h and the y coordinate of the vertice is k.
Then h=-3 and k =-11
Finally the equation
in vertex form is:

Answer:
Step-by-step explanation:
the slope is -3/2
equation: y=-3/2x +4
Answer:
x = -25
Step-by-step explanation:
Hi there!
In order to solve this, add 50 to both sides to isolate x.
x = -25
Hope this helps!
