Answer:

A

Step-by-step explanation:

|5x+2|=8 this mean that:

5x+2=8 and 5x+2=-8

5x+2-2+8-2 and 5x+2-2=8-2

5x=6 and 5x=-10 then divided both sides by 5

x=6/5 and x=-2

What is the slope of a line that is parallel to the line whose equation is ax+by=c?
miskamm [114]

Answer:

-a/b

Step-by-step explanation:

ax+by=c

First get the equation in slope intercept form ( y= mx+b  where m is the slope and b is the y intercept)

Subtract ax from each side

ax+by -ax=-ax +c

by = -ax+c

Divide each side by b

by/b = -ax/b + c/b

y = -a/b * x + c/b

The slope is -a/b and the y intercept is c/b

We want the line parallel so it has the same slope, -a/b

A married couple together earns 110,000 a year. The wife earns 16,000 less than twice what her husband earns.what does the husba
Alex17521 [72]
If we place what the husband earns as h and what the wife earns as w, we can begin...
w + h = 110000

but w = 2h - 16000

We can turn it into..

2h - 16000 + h = 110000

Which we can then combine into..

3h - 16000 = 110000

Add 16000 and..

3h = 126000

Divide by three...

h = 42000

(nice)

The husband earns 42,000$ a year

Bonus: The wife then earns 68,000$

42,000 (or h) + 68,000 (or w) = 110,000

Because this is the original equation, we are correct.
