Answer:
see below
Step-by-step explanation:
Multiply each of the coordinates by the dilation factor:
A' = (1/2)A = 1/2(6, 4) = (3, 2)
Point A gets transformed to point A'(3, 2), matching choice B.
This problem is quite simple, but it may seem tricky at first.
y is a function of x, so replace y with f(x)
You get f(x) = 2x - 4
D is your answer.
Have an awesome day! :)
We are given the ratio of 1/2 inch: 18 miles
Multiply both sides of the ratio by 2. I'm doing this so that the "1/2" turns into "1"
So we go from this ratio
1/2 inch: 18 miles
to this ratio
1 inch: 36 miles
which means that every inch on paper represents 36 miles in real life
----------------------------------------------------------------
The question is now: if two towns are 2.5 inches apart on paper, then how far are they in real life? (note: 2.5 is the decimal form of 2 and a half)
To find out, multiply both sides by 2.5
1 inch: 36 miles
2.5*(1 inch): 2.5*(36 miles)
2.5 inches: 90 miles
--------------------------------------------------------------------------
Answer: The two towns are 90 miles apart in real life
Answer:
18.04%
Step-by-step explanation:
discount = 28.00 - 22.95 = $5.05
Percent saved = 5.05*100 / 28 = 18.04%
