Hi there! The answer is 30 hours.
Let the number of worked hours be represented by X.
The total earn of option 1, would then be 10X + 60
The total earn of option 2, would then be 12X
We end up with the following equation:
Subtract 10X from both sides.
Divide both sides by 2.
Therefore, after 30 hours of work Rebecca will earn the same amount of money.
First, add together the costs for buying their own stuff. 250+135+69+25=479.
Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
Your original equation has no y-variable. It results in x = -2/3 when you solve for x which is a vertical line. Thus, if you want a line parallel to this that goes through point (- 1, - 4), you just set x equal to the x-value in that ordered pair.
Your parallel line is x = - 1.
Yes, (2,4) is the solution of 2x-7y<-10
