It would be 1/8. 2 to the third is 8, and all three answers correct is one option.
20 is the slope and 30 is the y-intercept
Step 1: Add the two equations together to get just one equation.
2x + y + x - y = 5 + 1
Step 2: Simplify.
3x = 6
Step 3: Divide by 3 on both sides.
3x / 3 = 6 / 3
x = 2
Therefore, the answer is x=2
Answer:
He will save $7,248 in 2 years.
Step-by-step explanation:
The whole explanation is in the picture :)
The constant of proportionality (r) appears to be 3.
y = 3x . . . . . . . x = number of tickets sold; y = dollars collected
