2(4-d+2d)=12
8-2d+4d=12
8+2d=12
2d=4
d=2
Answer:
(-1, 6)
Step-by-step explanation:
A graphing calculator shows the vertex to be (x, y) = (-1, 6).
__
You can also find it by putting the equation into vertex form.
y = -2(x^2 +2x) +4
y = -2(x^2 +2x +1) +4 +2(1) . . . . . add 1 inside parens; the opposite outside
y = -2(x +1)^2 +6
Compare to ...
y = a(x -h)^2 +k
and you see a=-2, h=-1, k=6
The vertex is (h, k) = (-1, 6).

Take a look at my notes. I hope this helps.
Answer:
6574900
Step-by-step explanation:
The equation of line is:

Further explanation:
The standard form of equation in point-slope form is:

Given equation is:
3x+2y=10
We have to convert it into point slope form, for which we have to isolate y on one side of equation

Comparing with standard form:
m = -3/2
As the new line is parallel to given line, their slopes will be equal
So,

To find the value of b, putting the given point (4,-5) in equation
