Ok so it's a proportion so this fraction is to this fraction. the smaller rectangle has sides 4 and 12. the larger one has 8 and x. so u set it up 4/12=8/x. the 4 and 8 r both the short sides so u want those on top and 12 and x r long sides so those on bottom. since that is not an answer option u can set it up as 8/4=x/12 because u still keep the variables of the same rectangle from being multipled with each other. so answer #2 is correct

What you have highlighted right now is correct. Because the rectangles are similar (proportional): l of rect 1 / l of rect 2 = w of rect 1 / w of rect 2

So, B. is the correct answer!

Let f(x)=x−4 and g(x)=−2x+4 Find g(f(2)) 0 −12 8 −8

marin [14]

Answer:

Step-by-step explanation:

This one is similar to the other one done with graphs , the only difference is we have equations instead of graphs.

Like the other one, we want to find f(2) and whatever that equals we plug into g(x) to find g(f(2))

So first lets find f(2)

f(x) = x - 4

f(2) = 2 - 4

f(2) = -2

g(f(2)) , f(2) = -2 , g(-2)

now lets find g(-2)

g(x) = -2x + 4

g(-2) = -2(-2) + 4

multiply -2 and -2 to get 4

g(-2) = 4 + 4

add 4 and 4 to get 8

g(-2) = 8

We can conclude that g(f(2)) = 8

Cookies are on sale! Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost

Anestetic [448]

Let's say that the price of each normal cookie is n.
The equation would then be 7(n - .75)=2.80.
Use distributive property, getting 7n - 5.25=2.80.
Add 5.25 to each side of the equation, getting 7n=8.05.
Divide 7 from both sides of the equation, getting n=1.15.

Point t bisects uv. find uv if ut = 4 1/2 yards

Fantom [35]

If a point bisects a segment, each line is congruent. So if UT is 4.5 yards TU would be 4.5 yards as well. UV is 9 yards
