Answer:
Standard form is Ax+By=C
move the x-value to the left: 1/2x+y=4
1/2x+y=4
or multiply by 2x+2y=8
Step-by-step explanation:
So basically in any paralellogram you have 2 pairs sides that are equal length and that are paralell to each other
hmm
we look at them that we have and look for matches
the only match we got is (-10,7) and (-10,-2)
means that one side is from (-10,7) o (-10,-2) and is 9 units long goint up
that (7,-4) must be the other poinr of the other side
since -4<-2, the missing point must be 9 units up from (7,-4)
9-4=3
(7,5) is the missing point
Answer: 19
Step-by-step explanation:
75 papers need to be marked
He grades 7 papers per hour
To find out how many paper he graded in 8 hours:
7 x 8
(7 is the number of papers graded in an hour)
(8 is the number of hours)
7 x 8 = 56
(56 is the number of papers he graded in 8 hours)
Now, there was a total of 75.
To find the remaining number of test sheets:
75 - 56
(75 is the total number of papers)
(56 is the number of papers graded)
75 - 56 = 19
Therefore, there are 19 papers remaining to grade.
2x+4 + 10 = 3x + 1
2x - 3x = 1 - 13
-x = -13
x = 13
AC = 2(13) + 4 + 10 = 26 + 14 = 40

We have the formula:

where M is the mark down, S is the original price and N is the reduced price. Plugging the values we know:

Therefore the original price was $15.95
