Answer:9 to 4 is 7 hrs divide 7 into 28.84 you get 4.12 so answer is $4.12 an hour
Step-by-step explanation:
Answer: .48
Step-by-step explanation:
Point 48 just move two places to the left
Solve for x in -7x - 8y = 9
x = -9 + 8y/7
Substitute x = -9 + 8y/7 into -4x + 9y = -22
4(9 + 8y)/7 + 9y = -22
Solve for y in 4(9 + 8y)/7 + 9y = -22
y = -2
Substitute y = -2 into x = -9 + 8y/7
x = 1
Thus,
<u>x = 1</u>
<u>y = -2</u>
Answer:The scale factor is (√10) / (4)
Explanation:The complete question as well as the rule for the distance between two points are shown in the attached image.
To get the scale factor, we will follow these steps:1- Length of AB:AB = √(5-9)²+(-4-4)²
AB = √80
AB = 4√5 units
2- Length of A'B':A'B' = √(5-6)²+(-4-3)²
A'B' = √50
A'B' = 5√2
3- getting the scale factor:A'B' = k AB where k is the scale factor
5√2 = k * 4√5
k = (√10) / (4)
Hope this helps :)
