Answer:
a. (-3,3), (18,-6), (9,15)
Step-by-step explanation:
If the scale factor is 3 and dilation is about the origin, each of the coordinates of the pre-image is multiplied by 3 to get the coordinates of the image.
Multiplying (-1, 1) by 3 gives (-3, 3), which matches choices A and C.
Multiplying (6, -2) by 3 gives (18, -6) which matches choices A and D.
The only viable choice is choice A.
Answer:
4.8 or about 5 miles
Step-by-step explanation:
In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in <em>one</em> mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.
The answer is neither. i hope this helps
Answer:
Step-by-step explanation:
eq. of line through (-4,0) and (3,2) is
y-0=(2-0)/(3+4) (x+4)
y=2/7 (x+4)
or y=2/7 x+8/7
m1=2/7
b1=8/7
eq. of line through (-3,2) and (4,0) is
y-2=(0-2)/(4+3) (x+3)
y-2=-2/7(x+3)
y=-2/7 x-6/7 +2
or y=-2/7 x+8/7
m2=-2/7
b2=8/7
m1b2+m2b1
