I believe you should do as much work as you can on each of these problems and only then ask for help.  You'll almost always learn more by becoming involved in the thinking and problem solving you encounter here.

|x| + 5 = 13  reduces to   |x| = 13, so x could be either -13 or +13.

Which equations could you use the division property of equality to solve?
julia-pushkina [17]

The equations are:

1. 2.35y = 4.70

2. k/3 = 17

3. 4 = 10w

4. 55x = 111

5. 8 = a/5

Answer:

the equations that apply are:

1. 2.35y = 4.70

3. 4 = 10w

4. 55x = 111

Step-by-step explanation:

We want to determine which if the equation we can use the division property of equality to solve.

1. 2.35y = 4.70

We can divide both sides by 2.35, so that

2.35y/2.35 = 4.70/2.35

y = 4.70/2.35

THIS WORKS

2. k/3 = 17

THIA DOESN'T WORK

3. 4 = 10w

dividing both sides by 10

4/10 = 10w/10

w = 4/10

THIS WORKS

4. 55x = 111

Divide both sides by 55

55x/55 = 111/55

x = 111/55

THIS WORKS

5. 8 = a/5

THIS DOESNT WORK

F(x) = 3x + 1 and f-1 =<br> then f(2)=
soldi70 [24.7K]

Answer:

f(x)= 3x + 1

f - 1 = 3x + 1-1

= 3x

f(x) -1= 3x

then f(2)= 3×2+1

=6+1

f(2)= 7.

f(-1)= 3×(-1) +1

= -3+1

f(-1)= -2
