Answer:
Step-by-step explanation:
(1,-10)....x1 = 1 and y1 = -10
(4,12)...x2 = 4 and y2 = 12
slope formula : (y2 - y1) / (x2 - x1)
slope = (12 - (-10) / (4 - 1) = (12 + 10) / 3 = 22/3 <==
Problem #11:
Twice a number (n) decreased by 5 is at least 11.
2n - 5 is = to or greater than 11.
2n - 5 is = to 11 comes out as 2n = 11 + 5, or 2n = 16, or n = 8.
If n = 8 or is greater than 8, 2n=5 will be at least 11.
Please, start work on the problems you haven't yet done. I'd be happy to comment on your own work and help you bring the solution to conclusion.
Answer:
the second one has the grater y nter...
Step-by-step explanation:
The answer is 2/45
1/5 times 2/9
1x2=2
5x9=45
plug in the answers to see which has an equal scale factor between mp and mt, and po and tr
if tr = 6, then the scale factor between po and tr is 1.5
that means, that in order to equal 9 mt would have to be 3
if mt = 3, then the scale factor between mp and mt would also be 1.5
therefore, since they both have an equal scale factor, the answer is
4) TR = 6
hope this helps!!
