From the given ordered pair representing Jacinda's progress, her speed is equal to 10 miles per hour. Letting x be the time it takes for Jacinda to catch up with Raj, the total distance Raj would travel is
1.5 + 4.5x
and Jacinda's total distance is 10x. Mathematically,
1.5 + 4.5x = 10x
The value of x from the equation is 0.27 hours. Therefore, Jacinda needs to run 2.7 miles to catch up with Raj.
He needs 1/2 cup because 3/4-1/4=2/4 which is simplified to 1/2
21/56 which reduces to 3/8 ...or if u need a percent, it is 37.5%
H is the correct answer. Y= (x+2)^2-5
2 to the left x+2=0 x=-2
