Answer:
The third one....
it fulfill all required characteristics of lines given.
7x + 12 = 3(5x - 12)
Step 1: Distribute the 3 to the numbers in the parentheses (5x and -12)
7x + 12 = (3 × 5x) + (3 × (-12))
7x + 12 = 15x + (-36)
Step 2: Combine like terms
x's go with x's (7x and 15x)
Subtract 7x to both sides
(7x - 7x) + 12 = (15x - 7x) + (-36)
(0) + 12 = 8x - 36
12 = 8x - 36
Normal numbers go with normal numbers
Add 36 to both sides
12 + 36 = 8x + (-36 + 36)
48 = 8x
Step 3: Isolate x by dividing 8 to both sides
48/8 = 8x/8
6 = x
Hope this helped!

Answer:
38 dimes, 50 quarters
Step-by-step explanation:
Let d = dimes
Let q = quarters
d + q = 88
d = 88 - q
0.10d + 0.25q = 16.30
0.10d + 0.25q = 16.30
0.10(88 - q) + 0.25q = 16.30
8.8 - 0.10q + 0.25q = 16.30
8.8 + 0.15q = 16.30
0.15q = 7.5
q = 50
d = 88 - q
d = 88 - 50
d = 38
Answer:
The answer is not an inverse function.
Step-by-step explanation:
The inverse function does not reverse. In other words, f(x) = x-5/10 and h(x) =10x+5 does not mirror.
