Can someone help me understand this?

Answers

Answer 1

Answer:

Get the equation to slope-intercept form: y = mx + b

6x + 3y = 6

Subtract 6x from both sides. This will give you 3y = -6x + 6.

Then, divide by 3 on both sides. This gives you y = -6x + 2.

2 is your y intercept and -6 is your slope.

Answer 2

Answer: Positive 6x is is subtracted on the left side, which in turn is moved to the right side. As 3y = -6x + 6 another way of saying this would be the inverse of 6x = -6x.

Answer:

11. 10/9 = 80/72

12. 8/12 = 72/108

13. 22/99 = 2/9

14 4 41/123 = 4 1/3

15. 84/840 = 1/10

16. 6/14 vs 3/7 (cross multiply numerators and denominators)

42 vs 42

Therefore 6/14 = 3/7

17. 2/3 vs 5/7 (cross multiply numerators and denominators)

14 vs 15

Therefore 2/3 < 5/7

18. 1/5, 1/2, 1/4 (Change to decimals then compare)

.20 .50 .25

Therefore increasing order is1/5, 1/4, 1/2

19. 5/7, 5/6, 7/9 (Change to decimals then compare)

.71 .83 .77

Therefore increasing order is 5/7, 7/9, 5/6

Rectangle sides have length 12 and 6, so it's perimeter is 2*12+2*6=24+12=36

Square has 4 sides equal in length so we divide 36/4=9

Length of each side of the square is 9 in.

It is not necessary to put so many question marks into question :)

$the\ perimeter\ of\ a\ rectangle=the\ perimeter\ of\ a\ square\n\n2\cdot(12+6)=4x\n\n2\cdot18=4x\ \ \ \Rightarrow\ \ \ 4x=36\ /:4\ \ \ \ \Rightarrow\ \ \ x=9\n\nAns.\ the\ length\ of\ each\ side\ of\ a\ square\ is\ 9\ in.$

the accountant charged $35 for the first hour of work and $23 for each hour he did after that he earned a totL or $127 how many hours did he work

Answers

He worked 5 hours in total: 35$ for the first hour, + 23 + 23 + 23 + 23 = 127$ for five hours of work.

The amount charged by the account in the first hour = $35
The amount charged by the accountant after first hour = $23
Total earnings of the accountant = $127
Let us assume that he worked for = x hours
then
35 + 23x = 127
23x = 127 - 35
23x = 92
x = 4
So from the above deduction we can conclude that the accountant worked for 4 hours. I hope the procedure is simple enough for you to understand.
