Answer:
The next in the first pattern is 15.
The next in the second pattern would be 3.
The next in the third pattern would be 32.
Step-by-step explanation:
In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)
In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)
The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
F-1(x) = 4
If you supply 3 for the function of F so F(3) =4x then 4x3=12
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-72 = 3(-4x - 8)
Step 2: Solve for <em>x</em>
<u>Distribute 3:</u> -72 = -12x - 24
<u>Add 24 to both sides:</u> -48 = -12x
<u>Divide both sides by -12:</u> x = 4
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-72 = 3(-4(4) - 8)
-72 = 3(-16 - 8)
-72 = 3(-24)
-72 = -72
