what is an equation of the line that passes through the point (-8,0) and is parallel to the line x+2y=14
dmitriy555 [2]
Answer:

y = -1/2x - 4

Step-by-step explanation:

First we wanna convert x + 2y = 14 into a slope-intercept equation.

x + 2y = 14

2y = 14 - x

y = 7 - x/2 or y = -1/2x + 7

Now that we have the line in slope-intercept form, we can solve for a line that is parallel to.

But first, what do parallel lines have in common? Parallel lines never intersect first of all and second they have the same slope so meaning we’re going to use -1/2 in order to find the equation of a parallel line so…

y = -1/2x + b

use the given point in the question

0 = -1/2(-8) + b

0 = 4 + b

b = 0 - 4

b = -4

The y-intercept of the line is -4

The equation of the line that passes through the point (-8, 0) and is parallel to the line x + 2y = 14 is y = -1/2x - 4

A mother is three times as old as her son and in eleven years she will be just twice his age find the present age of the son and
slega [8]

Answer: Mom = 33 Son = 11

Step-by-step explanation:

A mother is three times as old as her son

Mom age =3x

AFTER 11 YEARS:

Son’s age =x+11

Mom’s age =3x+11

Also, she will be just twice his age

3x+11 = 2*(x+11)

or,3x+ 11 = 2x +22

or,3x-2x= 22–11

or, x=11

Son’s age = 11 years and mom’s age = 33 years

Helppppp1!!\<br><br> (2x+4)=-4(-2x-6)
yulyashka [42]

Answer:

x=-10/3

Step-by-step explanation:

(2x+4)=-4(-2x-6)

distribute -4 to (-2x-6) by multiplying 

negative multiplied by a negative is a positive 

8x+24=2x+4

subtract 24 from each side 

8x=2x-20

subtract 2x from each side 6x=-20

divide both sides by 6 

-20/6 

simply to -10/3 or -3 1/3 or -3.3

x=-10/3

hope this helps! if you have any questions please ask!
