It should be d. , Because if you take the equation 3x+y=9, and make it slope intercept form, it would be y= -3x+9. -3 is the slope, and 9 is the y intercept. D is the answer.
Answer:
a) w = 8; y = 5.25
b) x = 10; z = 7.2
Step-by-step explanation:
a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.
6 = (3/4)w
w = 24/3 = 8
y = (3/4)·7 = 21/4 = 5.25

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.
6 = (3/5)x
x = 30/3 = 10
z = (3/5)12 = 36/5 = 7.2
Answer:
The answer would be he sold 11 packs of baseball cards at $0.75 each.
Step-by-step explanation:
11 packs of cards at 75 cents each.
35/8 = 4.376 5/3 = 1.666… 4.376/1.666…
Therefore 2.625 pieces
Ah! Inverse variation!
What divided by 2 is 8? 16
16 divided by what is 3
16/3
