Answer:a
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
- 6x +5 = 0
- 6x + 9 -9 +5 = 0
[
- 6x + 9] - 4 =0
-4 = 0
= 4
(x-3) =
or (x-3) = - 
(x-3) = 2 or (x-3) = -2
x = 5 or x = 1
therefore, sum of these solutions is 5+1 = 6
Answer:
y=-3/4x + 0.25
Step-by-step explanation:
(76.4)(0.32)(R - 112) + (0.35)(20R + 435) = 54
24.448(R - 112) + 7R + 152.25 = 54
24.448R - 2738.176 + 7R + 152.25 = 54
31.448R - 2585.926 = 54
31.448R = 54 + 2585.926
31.448R = 2639.926
R = 2639.926/31.448
R = 83.9457
