angle y= 180 -42 which gives u 138
Answer:
The expression = -75
Step-by-step explanation:
Evaluate: Enter a number for each variable.
−x2+7(y+2)−1
x=
5
y=
-9
Evaluate for x=5,y=−9
−52+7(−9+2)−1
−52+7(−9+2)−1
=−75
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form
, where h and k are real numbers, the roots are
and
.
Our parabola has a plus, though. That's a problem, right?
No!
, so there's no problem. So, our roots are
and
.
So, the answer is A and we're done!
With a 15 year or 180 month mortgage they will pay out $133,680.60 compared to the 30 year or 360 month mortgage they will pay out $183,988.80 which is $50,308.2 more. So they would save $50,308.2 if they select the 15 year mortgage.

3x - 14 = x + 2
- x - x
2x - 14 = 2
+ 14 + 14
2x = 16
2 2
x = 8
4y - 7 = y + 11
- y - y
3y - 7 = 11
+ 7 + 7
3x = 18
3 3
x = 6
(x, y) = (8, 6)
The answer is D.
