You must use quadratic formula for each.
The term in front of the
is the "a" value in the quadratic formula. The term in front of the
is the "b" value. And the constant term (no x's) is the "c" value. Now you must simply substitute these values into the quadratic formula for each question.

For this case we are going to define the original coordinates:
(x, y): original coordinates.
We apply the transformation:
(x, y) -------> (-x, y + k)
We have:
-x: reflection on the y axis.
y + k: translation k units up.
Answer:
The point was reflected over the y-axis and translated up.
Answer:
18
Step-by-step explanation:
3(2)+2(4)+4=
6+8+4=18
Answer:
x = -2, y = 3.
as an ordered pair it is (-2, 3).
Step-by-step explanation:
y= 2x + 7
y= -4x - 5
As both right hand expression are = y we have:
2x + 7 = -4x - 5
6x = -12
x = -2
Substitute for x in equation 1:
y = 2(-2) + 7 = 3.
It’s in scientific, currently. So you want to put it back the way you’d write it normally. Move the decimal two places to the right (bc x 10^2) to get 338.55
