Answer: 4.2 miles
Step-by-step explanation:
So she ran 6 miles in 50 minutes how long will she run in 35 minutes?
So the equation will therefore be:
6=50
x=35
Cross multiply
6 x 35 = 50x
210 = 50x
Divide both sides by 50
The answer is 4.2 miles
Answer:
7mm
Step-by-step explanation:
A parallelogram has 2 sets of equal sides, so if one side is 7mm, then the opposite side is too.
Over which interval(s) is the function decreasing?
Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.
f ( x ) = - ( x + 1)^2 + 4
