#3-60 Simplify the following expressions.

Answers

Answer:

The solution is:

a. -18

b. -18

c. 24

d. 0

e. -4

4. 4

Step-by-step explanation:

Before we get into the solution, we remember the formula first, namely:

Addition

• (-) + (-) = (-)

• (+) + (+) = (+)

Subtraction

• (+) - (+) = can (-) and (+)

• (+) - (-) = (+)

Multiplication

• (-) x (-) = (+)

• (+) x (-) = (-)

Division

• (-) : (-) = (+)

• (+) : (-) = (-)

Solution:

a. 6(-3) = -18 ((+) × (-) = (-))

b. -6(3) = -18 ((-) × (+) = (-))

c. (-8)(-3) = 24 ((-) × (-) = (+))

d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)

e. -20÷5 = -4 ((-) ÷ (+) = (-))

f. -36÷(-9) = 4 ((-) ÷ (-) = (+))

what is 6n + 7 - 2n - 14 = 5n + 1

Answers

Answer:

-7 is what i got

Step-by-step explanation:

combine like terms.. 6n -2n= 4n

7-14= -7

4n-7= 5n+1

+1 becomes -1

4n- -6=5n

-4n on both sides

-6= 1n

1-1 on both sides to cancel out

n= -7

N = -8

6n-2n-5n=1+14-7
-1n=8
n=-8

What value of Y makes the equation true ?

Answers

Answer:

y = -5/2 or -2.5

Step-by-step explanation:

3y + 4 = -y - 6

add y to both sides

4y + 4 = -6

subtract 4 from both sides

4y + 4 - 4 = - 6 - 4

4y = -6 - 4

4y = -10

divide both sides by 4

4y/4 = -10/4

y = -10/4

y = -5/2 or -2.5

Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

P.S. wouldn't mind getting brainliest

Answer:

D

Step-by-step explanation:

Frist you find negative 2 and you can see that 2 are going there so you need to find where negative 3 is when you add negatives they trun into a possitve so go up 3 times from negative 2.

6 - 3x = 2x - 24

Answers

Answer:

x=6

Step-by-step explanation:

rearrange terms, subtract 6 from both sides, simplify, subtract 2x from both sides, simplify, divide both sides by -5, and finally you get 6.

Answer:

x=6

Step-by-step explanation:

6 - 3x = 2x - 24

move the x together and the numbers together

REMEMBER: when you move a something from one side of the equation (not including multiplication and division) to the other, change the sign in-front of it (+ or -)

NOW CONTINUE WITH THE PROBLEM -->

-3x-2x = -24 - 6

now subtract,

-5x = -30

and divide -30 by -5

Since there are 2 negative numbers, the result would be positive -->

and for x, you would get:

x=6

Answers

x = 1.6

f = 0.5

0.5(x) = 8x -12

subtract 8x from both sides

-7.5x = -12x

Divide by -7.5x, both sides

X=1.6
