Quadrilateral abcd has been mapped to the image, quadrilateral a′b′c′d′, using the function f, as shown in the graph.

which answer choice correctly describes the function f?

a. f: (x, y)↦(x+2,y+3)
b. f: (x, y)↦(x−2,y−3)
c. f: (x, y)↦(x−2,y+3)
d. f: (x, y)↦(x+2,y−3)

D. f:(x,y)↦(x+2,y−3)

Step-by-step explanation:

Points have moved 2 units right and 3 units down

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
