1 mile = 5280 feet
81 * 5280 = 427680 feet per hour
1 hour = 3600 seconds
427680 / 3600 = 118.8 feet per second
118.8 * 15 = 1782 feet in 15 seconds
10(4^2-(9)
Since 16-9 is 7
And 10 times 7 is 70
Step-by-step explanation:
How to simplify
-6x (some sign, it didn't show in the question)30
Divide by -6 on both sides to isolate the variable.
30 divided by -6 is -5, so x=-5.
Slope intercept y=mx + b, add y to both sides in your equation. Y=4x, slope intercept. Graphing should be easy, just plug in x intercepts
