Answer:
a = 1
b = -1
Step-by-step explanation:
First, let's make equations out of those given f(x)'s
-4 = -3a + b
2 = 3a + b
We can use elimination method to get rid of the a real quick
-4 = b
2 = b
Add those together
-2 = 2b
Divide both sides by 2
-2/2 = 2b/2
b = -1
Plug in the new b in one of the original equations; I'm gonna use the bottom one
2 = 3a - 1
+ 1 + 1
3 = 3a
3/3 = 3a/3
a = 1
Answer:
the answer is 96
Step-by-step explanation:
- 9
-3
100-
-3
100-1-3
96
Since sum indicates addition, you want to add the two terms together.
B + (5x2)
If the answer needs to be simplified, you can do the multiplication to get:
B + 10
