For your 4 question option b
Answer:
See Below
Step-by-step explanation:
#17. You just have to plot the points, this should be super easy. Go to the left 6 (because it is negative) then up four. This is M. Then go right 5 and up 4 and plot A.
#18. Point T is a reflection of A over the X-axis. This is quite simple as well. All you need to do it make your Y coordinate negative? Why Y? You'll see. You need to essentially "fold" the graph at the X line, so your Y value goes from up top at 4 to below the X axis as we're reflecting over the X line. I hope that makes sense. T should be at 5,-4
#19 This is the same process as 18, Over the X coordinate. Make Y negative and plot it. It should be H= -6,-4
#20 You can get this from the answers from #18 and #19.
#21. The formula is Base*2+Height*2, or Base+Base+Height+Height. You want the distance around. I'll have you figure this out, but if you get comment and I'll check back. How many steps do you go up from T to A? How about over from H to T 9 or (M to A)? Once you find how many units your base and height are, use the formula for perimeter to find the answer. Hope this helps! :)
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.
Best of Luck!
Answer:
5 2/5
Step-by-step explanation:
First, determine how many times 5 can go into 27 evenly, there should be no decimals! Therefore, 5 can go into 27, 5 times. Next, we know that there are 2 left over. This leaves us with 5 and 2/5.
Hope this helps!! :)
Solve by Substitution
Answer:
x = -5
y = -2
