Answer:
Step-by-step explanation:
5.
point = (x, y)
A = (
, 12)
B = (
, 20)
C = (3, 24)
D = (
, 28)
y/x ratios


24/3

6.
(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2
(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2
(3, 7) = 7 ÷ 3 = 2 1/3
(4 1/2, 9) = 9 ÷ 4 1/2 = 2
The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.
The other ratios are equal to each other and are therefore in proportion.
7. yes
Answer: Trinomials often (but not always!) have the form x2 + bx + c. ... So, how do you get from 6x2 + 2x – 20 to (2x + 4)(3x −5)? Let's take a look. Factoring Trinomials
Step-by-step explanation:
