Answer:
(-1,8)
(4,-27)
Step-by-step explanation:
y+7x=1
Let x = -1 and find y
y+7(-1)=1
y -7 =1
Add 7 to each side
y-7+7 = 1+7
y = 8
(-1,8)
Let x = 4 and find y
y+7(4)=1
y +28 =1
Subtract 28 from each side
y+28-28 = 1-28
y = -27
(4,-27)
Answer: Yes
Step-by-step explanation:
I'm pretty sure it's correct so yes
Answer:
18 inches wide
Step-by-step explanation:
Since the ratio of width to length is 3:7 we can assume that the length will be substancially longer than the width. The length is given as 42 inches long. To find how big the scale factor is, we divide 42 by 7 to get 6. 6 is our scale factor. take 3 x 6 =18 inches wide.
Hope this helps! :)
Answer:
<h2><em><u>1st</u></em><em><u> </u></em><em><u>option</u></em><em><u> </u></em></h2>
Step-by-step explanation:
Place the compass at one end of line segment, and taking it more than 1/2 of MN is its 1st step
1.
15h = 75
15h/15 = 75/15
h = 5
2.
-d = -6
-d(-1) = -6(-1)
d = 6
3.
5k = 25
5k/5 = 25/5
k = 5
4.
13 = -x/2
-x/2 = 13
-x/2 * (-2) = 13 * (-2)
x = -26
