Which numbers are 4 units from -2 on the number line
Artemon [7]

Let the number be x


Then the absolute value of the number from -2 should be 4


|x--2|=4


|x+2|=4


So either



(x+2)=4


x=4-2=2


Or


-(x+2)=4


x+2=-4



x=-4-2



x=-6



[tex] <B>The numbers are 2 and -6</B> [/tex[


They are four units away from -2 on the number line

Simplify the expression below. Show your Work.
lord [1]

Answer:

7y + 24

Step-by-step explanation:

Think of the negative sign to the left of the parentheses as being -1. Then apply the distributive property. The effect of a negative sign to the left of parentheses or a 1 to the left of parentheses is that each term inside the parentheses changes sign.

-(-7y - 24) = -1(-7y - 24) = (-1)(-7y) - (-1)(24) = 7y - (-24) = 7y + 24

Stels [109]

Answer:

y = 9.8x + 6.7

y = 6.7x + 9.8

y = 7.5x + 3.8

y = 3.8x + 7.5

Step-by-step explanation:

I made 2represent x.

y= 9.8(2) + 6.7

y = 26.3

y=6.7(2) + 9.8

y= 23.2

y= 7.5(2) + 3.8

y= 18.8

y= 3.8(2) + 7.5

y= 15.1

Given y=5x−3 with the domain D: {−2, −1, 0, 1, 2}, fill in the missing values of the table below.
spayn [35]

Answer:

see below

Step-by-step explanation:

y = 5x-3

Let x = -2  y = 5(-2) -3 = -10 -3= -13

Let x = -1  y = 5(-1) -3 = -5-3 = -8

Let x = 0   y = 5(0) -3 = 0-3 = -3

Let x = 1     y = 5(1) -3 = 5-3 = 2

Let x = 2   y = 5(2) -3 =10-3 = 7
