Answer:
Step-by-step explanation:
<u>Given system</u>
<u>Solve by elimination, subtract the equations and solve for y:</u>
- 18x + 6y - 18x - 22y = 30 - 14
- -16y = 16
- y = -1
<u>Find x by substituting y:</u>
- 18x + 6(-1) = 30
- 18x - 6 = 30
- 18x = 36
- x = 36/18
- x = 2
<u>The answer is</u>: (2, -1)
Answer:
b = 26°
Step-by-step explanation:
a ; b = complementary =>
a + b = 90° } => b = 90° - 64° = 26°
a = 64°
I believe the answer is x = 1
Answer:
f = 12(s - 35).
Step-by-step explanation:
The number of miles per hour he was over the limit = s - 35.
So his fine f is:
f = 12(s - 35).
