Answer:

x = ± 7

|-7|-2=5

|7|-2=5

± means positive or negative

Step-by-step explanation:

|x|-2=5

Get x by itself by adding 2 to both sides.

x - 2 + 2= 5 + 2

-2 + 2 cancels out

x = 5 + 2

x = 7

Absolute value is how far a number is from 0.

x can be either positive or negative.

Alex is making puppets for a show. He bought all the string needed for $125. It costs $18 for the remaining materials to make ea

Alexus [3.1K]

Alex bought all the string needed for $125.

It costs $18 for the remaining materials to make each puppet.

So if we closely observe then we see that here $125 is the fixed cost because its not going to change with number of puppets.

And the variable cost is $18.

In this case we can model a Total cost function C(x) for for x number of puppets as below

$C(x)=125+18x\\ \\ \text{Here x is the number of puppets}\\ \\ \text{Since in our case the number of puppets is 50 so replace x by 50 we get }\\ \\ C(50)=125+18*50\\ \\ C(50)=125+900\\ \\ C(50)=1025 \ dollar.$

The total cost to make 50 puppets=$1025
