Answer:

Answer:

C. Associative Property of Multiplication

Step-by-step explanation:

The associative property of multiplication is a.(b.c) = (a.b).c

The associative property of multiplication is true for all the real numbers.

Let me show you an example.

Let's take a = 2, b= 5 and c = -2

a.(b.c) = 2.(5.-2)

=2(-10)

= -20

(a.b).c = (2.5).-2

= 10.-2

= -20

You can see a.(b.c) = (a.b).c

-20 = -20

So the associative property of multiplication holds good.

Given: 3.(x.y) = (3.x).y

It is an example of "associative property of multiplication"

Even if we change the brackets and multiply the terms, the result will be the same.

Solve the equation: Show work step by step

-14=-5+3c

Answers

-14 = -5 + 3c

First, regroup your terms. / Your problem should look like: -14 = 3c - 5
Second, add 5 to both sides. / Your problem should look like: -14 + 5 = 3c
Third, simplify -14 + 5 to -9. / Your problem should look like: -9 = 3c
Fourth, divide both sides by 3. / Your problem should look like: -(9)/(3) = c
Fifth, simplify the fraction to 3. / Your problem should look like: -3 = c
Sixth, switch your sides. / Your problem should look like: c = -3

Answer: c = -3

−14=−5+3c

−14=3c−5

Flip the equation.

3c−5=−14

Add 5 to both sides.

3c−5+5=−14+5

3c=−9

Divide both sides by 3.

3c/3=−9/3

c=−3

If 7 + 3x = 22, then 2x =

Answers

7+3x=22\ \ \ /-7\n3x=15\ \ \ /:3\nx=5\n\n\n2x=2\cdot5=10

Hey there!

7 + 3x = 22

3x + 7 = 22

SUBTRACT 7 to BOTH SIDES

3x + 7 - 7 = 22 - 7

CANCEL out3 7 - 7 because it give you 0

KEEP: 22 - 7 because it help solve for the x-value

NEW EQUATION: 3x = 22 - 7
SIMPLIFY IT!
3x = 15

DIVIDE 3 to BOTH SIDES

3x/3 = 15/3

CANCEL out3 3/3 because it give you 1

KEEP: 15/3 because it help solve for the x-value

NEW EQUATION: x = 15/3

SIMPLIFY IT!
x = 5


Therefore, the answer: x = 5


Now that we know what your x-value is.. we can substitute it in your next equation


2x

= 2(5)

= 2 + 2 + 2 + 2 + 2

= 4 + 4 + 2

= 8 + 2

= 10

5 = 5

x = 5 ☑️


Therefore, your overall answer is: x = 5


Good luck on your assignment & enjoy your day!

Let f(x) = -x + 5 and g(x)=3x+ 2. Find f(x) – g(x).

Answers

Answer: f(x) - g(x) = -4x+3

=============================================

Work Shown:

f(x) - g(x) = ( f(x) ) - ( g(x) )

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

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

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

f(x) - g(x) = -4x+3

In step 3, make sure to distribute the negative to everything in the parenthesis for (3x+2)
