Answer:
C
Step-by-step explanation:
A is a horizontal line on 3
B will cross the y axis at (0, -3), and the x axis (3, 0)
D will cross the y axis (0, 1) and the x axis (-0.5, 0)
As C does not have a y-intercept or x-intercept, it will it (0, 0)
- 4 = 3x
= 3x + 4 <em>added 4 to both sides</em>
6x + 8 = 2(3x + 4) <em>multiplied both sides by 2</em>
6x + 8 = 6x + 8 <em>distributed 2 on the right side</em>
8 = 8 <em>subtracted 6x from both sides</em>
TRUE
Since this makes a trues statement, then there are infinite solutions

Answer:
6. 4.8m
7. a. 48 b. 31.4 c. 170
Step-by-step explanation:
6. 4.5^2 x 1.6^2 = c^2
22.81 = c^2
square root of 22.81 = 4.8
7.
a. 12^2 x 16^2 = c^2
400 = c^2
square root of 400 is 20, 20 + 12 + 16 = 48
b. 9^2 x b^2 = 13^2
88 = b^2
square root of 88 is 9.4, 9.4 + 9 + 13 = 31.4
c. 25^2 x b^2 = 65^2
3600 = c^2
square root of 3600 is 60, 60 + 60 + 25 + 25 = 170
3(4+3r)
= 12 + 9r
