To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
Answer:
C
Step-by-step explanation:
The answer is going to be miles per quart. So B is wrong.
12 gallons allows you to travel 192 miles
1 gallon permits 192 / 12 = 16 miles / gallon. (Must be a truck of some kind).
1 gallon permits 16 miles of driving.
4 quarts (in 1 gallon) permits 16 miles of driving.
1 quart gives 16/4 = 4 miles / quart.
The answer is C.
==========================
There is a slightly shorter way
12 gallons contains 12 * 4 quarts = 48 quarts.
48 quarts permit 192 miles
1 quart permits 192/48 = 4 miles
4miles / quart.
The answer is still C
Answer:
y+2=1/2(x+1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(3-(-1))
m=(0+2)/(3+1)
m=2/4
m=1/2
y-y1=m(x-x1)
y-(-2)=1/2(x-(-1))
y+2=1/2(x+1)
<h3>
Answer: x = 3</h3>
To get that answer, we replace y with 8 and then isolate x.
5x-7 = y
5x-7 = 8
5x = 8+7
5x = 15
x = 15/5
x = 3
