So the roc(rate of change) here would be 18/15 which simplifies to 1.2 and then just mutiply this by 50 to get...
60 miles
Answer:
Step-by-step explanation:
Distance Formula: 
Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>:
Answer:
$15
Step-by-step explanation:
let the hourly rate of pay for Ben = B
let the hourly rate of pay for Judy = J
Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;
4J + B = 75 ----- i
Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120
2J + 6B = 120 --- ii
Now, we should solve the expression;
Multiply equation ii by 2 and equation i by 1;
4J + B = 75 ----- i x 1 ; 4J + B = 75 -- iii
2J + 6B = 120 --- ii x 2 ; 4J + 12B = 240 ---iv
Now,
equation iv - iii;
11B = 165
B = $15
So, solving for J;
4J + B = 75
4J + 15 = 75
4J = 75 - 15 = 60
J = $15
Answer: -1 1/2 to -1: -1 1/3 and -5/4
-1 to -1/2: -2/3, -3/4, -6/7, -5/6
-1/2 to 0: -1/3 and -3/8
0 to 1/2: 1/5, 1/10, 3/12, 3/8, 3/7, 1/3
1/2 to 1: 4/5, 6/10, 7/8, 7/9, 3/4, 8/10
1 to 1 1/2: 1 5/12, 9/8
Step-by-step explanation:
(-x + 7)(x + 5)
Bc if you split -x^2 and 35 into 2 parts to get 2x it’ll be x(7)= 7x & -x(5)= -5x —> 7x-5x=2x
(I hope that made sense?)
