Answer:
2x + y = 3 becomes y = 3 - 2x
-2x + y = -1 becomes y = -1 + 2x
2x + y = 5 becomes y = 5 - 2x
Parallel: 2x + y = 5
Perpendicular: 0.5x + 7
neither parallel nor perpendicular to line a: -2x + y = -1
ANSWER
x= 46
EXPLANATION
To solve this problem you need to remember that a straight line is 180°. This figure is basically a straight line split in two, so 134°+x=180°. You can also subtract 134 from 180 to get 46.
Answer:
Part A:
Company A equation: 22d + 5 = c
Company B equation: 20d + 16 = c
d - days
c - cost
Part B:
If you had rented a car from Company B for 9 days it would be less than if you rented a car from Company A for 9 days. If you plug 9 in for "d" in both equations, the total cost for Company A's would be $203, while Company B's would be $196.
Part C:
You would save $19
Answer:
-14
Step-by-step explanation:
h(-8)=-2(-8+5)^2 +4
= -2(-3)^2 +4
= -2(9) +4
=-18+4
= -14
