Kerry has 5 metal and 3 wood
Ray Of Light [21]

Expression

(5+3)+(5x2)=p

Solution

18

(Step-by-Step)

In this expression we simply have to use basic PEMDAS (Parenthesis Equation Multiplication Division Addition Subtraction) Order.

We start by working out the parenthesis

5 + 3  and 5 x 2

First let's work out our metal and wood paperweights

5+3=8

Simple enough, we have 8 metal AND wood paperweights

Now we have to work out our glass paperweights.

We have twice as many glass as we do metal PW's  meaning we need to multiply the 5 metal paperweights by 2

5x2=10

This simplifies and boils our equation down to

8+10

simply solve and add the two and you have your answer

18

Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(-2)).
Eva8 [605]

Answer:

We conclude that:

f(g(-2)) = -3

Step-by-step explanation:

Given

  • f(x) = 2x + 7
  • g(x) = x-3

To determine

  • f(g(-2)) = ?

In order to determine f(g(-2)), first we need to determine g(-2)

so substituting x = -2 in g(x) = x-3

g(-2) = -2 - 3

        = -5

Thus,

f(g(-2)) = f(-5)

now substitute x = -5 in the function f(x) = 2x+7

f(x) = 2x+7

f(-5) = 2(-5) + 7

f(-5) = -10 + 7

f(-5) = -3

so

f(g(-2)) = f(-5) = -3

Therefore, we conclude that:

f(g(-2)) = -3
