Answer:
f(4) = 49
f(-3) = -35
Step-by-step explanation:
f(4) = 12(4) + 1 = 48 + 1 = 49
f(-3) = 12(-3) + 1 = -36 + 1 = -35
0.75 is 3/4 or 6/8, which is less than 7/8
= 2a - 1
2(
) = 2(2a - 1) <em>multiplied both sides by 2 </em>
ab = 4a - 2 <em>distributed the 2 on the right side</em>
ab - 4a = -2 <em>subtracted 4a from both sides</em>
a(b - 4) = -2 factored out "a" from the left side
a =
<em>divided (b - 4) on both sides</em>
Answer: a =
The first one is -4 and the second one is 6.
