Answer: a= b/ b+2
Step 1: factor out variable a.
a(b+2)= b
Step 2: divide both sides by b+2.
a(b+2)/ b+2 = b/b+2
There is no graph to determine
The correct answer is C, because when we plug in f(1), we get:
Answer:
7) m = 6
8) k = 15
9) a = -12
10) x = 1
11) n = 4
12) r = 11
Step-by-step explanation:
<h3><u>Solution</u> : </h3>
Solving all the questions step by step!
7) 1 = 6+m/12
- Hence, the value of m is 6.
8) 8 = 3 + k/3
- Hence, the value of k is 15.
9) -4(-8+a) = 80
- Hence, the value of a is -12.
10) 8(x-1) = 0
- Hence, the value of x is 1.
11) n/2 - 1 = 1
- Hence, the value of n is 4.
12) 1 = r-3/8
- Hence, the value of r is 11.
