Distribute.
9(times)3 + 8x(times)9
27+72x is an equivalent expression
Okay so since we have to put 252 miles per 8 gallons into the simplest form I'm going to say that we divide 252/8=31.5 so we should have 31.5 miles per gallon as our answer
Answer: 14n + 6
Step-by-step explanation: Product is multiplication so 14 times a number or n is 14n, increased by 6 so 14n+6
Answer:
See below.
Step-by-step explanation:
Use the quadratic function f(x) = -x^2 - 6x. The parabola faces downward with y -intercept (-3,9) and zeros (-6,0) and (0,0). See the attached graph.
The axis of symmetry will serve as a ladder through the coaster at x = -3.
f(x) = 24 - 2x
f(2) This means that x is 2, so you can plug in 2 for x
f(x) = 24 - 2x
f(2) = 24 - 2(2)
f(2) = 24 - 4
f(2) = 20
To find x when f(x) = 10, you can do:
f(x) = 24 - 2x [substitute/plug in 10 for f(x)]
10 = 24 - 2x Subtract 24 on both sides
-14 = -2x Divide -2 on both sides
7 = x
