Answer:
B
Step-by-step explanation:
B and D are the only ones with the same slope (-3x) which is required for the line to be parallel.
and if you graph it out, you will find that B is the correct answer because it passes through (2,-4).
3.4 = -13.6 - 3.4c + 1.7c
3.4 = -13.6 - 1.7c
1.7c = -13.6 - 3.4
1.7c = 17
c = 10
Answer:
D. 60=(x+45)
Step-by-step explanation:
They are the same degree so they should equal eachother
Answer:
c
Step-by-step explanation:
its c because i got 100% on the topic test
(4x + 7)² = 60
(4x + 7)(4x + 7) = 60
(4x² + 28x + 28x + 49) = 60
4x² + 56x + 49 = 60
<u> -49 -49</u>
4x² + 56x = 11
4x² + 56x - 11 = 11 - 11
4x² + 56x - 11 = 0
x = <u>-56 +/- √(56² - 4(4)(-11))</u>
2(4)
x = <u>-56 +/- √(3136 + 88)</u>
8
x = <u>-56 +/- √(3174)</u>
8
x = <u>-56 +/- 56.34</u>
8
x = -7 +/- 7.0425
x = -7 + 7.70425 x = -7 - 7.70425
x = 0.70425 x = -14.70425
