Answer:
-5
Step-by-step explanation:
f(-2) means that -2 is going to be our input in this function.
To solve this, simply substitute -2 for x in the expression given.
If f(x) = 3x+1, then f(-2) = 3(-2) + 1
3(-2)+1 = -6+1 = -5

Hi
3 dinners at $9 each.
9 x 3
2 kids' meals at $4 each
9 x 3 + 4 x 2
4 desserts at $3 each
9 x 3 + 4 x 2 + 4 x 3
$10 dollar off coupon
9 x 3 + 4 x 2 + 4 x 3 - 10
Solve using PEMDAS
9 x 3 + 4 x 2 + 4 x 3 - 10 = ?
27 + 8 + 12 - 10 = ?
35 + 12 - 10 = ?
47 - 10 = ?
37
The answer is 37

Step-by-step explanation:
Remark
You have to guess what the question is. I'm assuming that it is either the black triangle to the blue one or the blue one to the black one. Be careful when you post a question to see if you have included a question.
Answer
<em>Ratio of blue to black</em>
The distance of the left most point of the blue triangle to the y axis is 3. The same point on the black one is 1
blue/black = 3/1
<em>Ratio of black to blue</em>
ratio of the black triangle to the blue one is 1/3
The answer will depend on the question. Notice that the two answers are reciprocals.
