which ordered pairs are a solution to the question y=8× select all that apply (-1,-7)(2,16)(1,8)(-2,-6)
1 answer:
Answer:
(2,16) , (1, 8)
Step-by-step explanation:
(-1,-7), x = -1 and y = -7
plug in
y = 8x
-7 = 8 * -1
-7 = -8, false
(2,16), x=2 and y = 16
plug in
y= 8x
16 = 8 * 2
16 = 16, so it is a solution
(1,8), x = 1 and y = 8
plug in
y = 8x
8 = 8 * 1
8 =8 , so it is a solution
(-2,-6), x = -2, y = -6
plug in
y = 8x
-6 = -2 * 8
-6 = -16, false

![S_{31} = 9 \cdot 31 + [-0.5 \cdot \frac{31(31-1)}{2}] = 46.5](https://tex.z-dn.net/?f=S_%7B31%7D%20%3D%209%20%5Ccdot%2031%20%2B%20%5B-0.5%20%5Ccdot%20%5Cfrac%7B31%2831-1%29%7D%7B2%7D%5D%20%3D%2046.5)
![S_{40} = 40 + [-3 \cdot \frac{40(40-1)}{2}] = -2300](https://tex.z-dn.net/?f=S_%7B40%7D%20%3D%2040%20%2B%20%5B-3%20%5Ccdot%20%5Cfrac%7B40%2840-1%29%7D%7B2%7D%5D%20%3D%20-2300)
Answer:
22
Step-by-step explanation:
x-1 is a midsegment.
According to the Triangle midsegment theorem, x-1 is half of the third side (42)
x-1 = 42/2
x-1 = 21
x= 22
or
2x-2=42
2x=44
x=22
