Answer:
y=x^28x+31
Step-by-step explanation:
30 minutes / 3 miles = 10 minutes for 1 mile
7 miles * 10 minutes per mile = 70 minutes total to run 7 miles
1 foot is shorter that 20 centimeters
The slope is -4 and the y-intercept is -12.
Answer:
x = 21/2
Step-by-step explanation:
Step 1: Write equation
-4(3/2x - 12) = -15
Step 2: Solve for <em>x</em>
- Distribute -4: -6x + 48 = -15
- Subtract 48 on both sides: -6x = -63
- Divide both sides by -6: x = 21/2
