8. The equation for the horizontal line passing through the points (-5,-4), (-2,-4), (3,-4) is :
Y: -4
Y: -5
Y: -2
Y: 3
Y: -4

9. What is the slope of a line represented by the equation 4x+2y=12?_

10. What is the name given to the point (0,0)?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

radha is now 5 years old

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

you first to choose the points and then move from then as the slope you have
