Answer:
so what are the equations you're having trouble with?
Answer:
C. -2
Step-by-step explanation:
You can use the formula:
(-2, 5) & (3, -5)
The slope is C. -2
140 / 100 * X = 56
X = 56 * 100 / 140 = 5600 / 140 = 40
Answer:
Step-by-step explanation:
- Mother's age = m
- Son's age = s
<u>3 years later:</u>
- m + 3 = 4(s + 3) ⇒ m = 4s + 12 - 3 = 4s + 9
<u>3 years ago:</u>
- m - 3 = 2(s + 8) ⇒ m = 2s + 18 + 3 = 2s + 21
<u>Solve for s by substitution:</u>
- 4s + 9 = 2s + 21
- 2s = 12
- s = 6
<u>Find the value of m:</u>
Mother is 33 and son is 6
