#2* 2. In Mr. Arthur's mathematics class, students were given a rectangular greeting card. The
table below shows the length and area of each card,
Card Side Length Area
() ()
А 6 in. 24 in,
B 9 in 36 in
C
15 in
60 in
Which equation represents the rate of change between the area of a card, y, with a side
length of x?
А
y=x+18
B
y 4x
C
y - 2x + 12
Dy X
4

the value of x is 28.2

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
