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

<em>capacity = 140 liters</em>
- Step-by-step explanation:
<em>1 h = 60 min</em>
<em />
<em>60 min ................ 240 l</em>
<em>35 min ...................... x l</em>
<em>x =35×240/60 = 8400/60 = 140 liters</em>
Radius of circle= 4
a) circle circumference=2(pi)r
circumference=2(pi)4=25.13
P=2W+2L
p=2(5)+2(10)
P=30
b) area of circle=pi(r^2)=pi(16)=50.27
area of rectangle=L×W= 5×10= 50
c) I think you can figure it put
.32 is 32/100
16/50
8/25 in simplest form
16x^2 -1 = 0
16x^2 = 1
x^2 = 1/16
x= 1/4
