I believe the answer is 60
1200 divided by 20=60
The solution to the system is (2,-1)
To make sure plug in the ordered pair into the system of equations
-2(2) - 3(-1) = -1
-4 - (-3) = -1
-1 = -1
3(2) + 6(-1) = 0
6 + -6 = 0
0 = 0
This ordered pair works and is your answer
(2,-1)
Answer:
Step-by-step explanation:
let x < 30 be the width of strip of lawn.
then (80-2x)(60-2x)=800
4800-160x-120x+4x²=800
4x²-280x+4000=0
x²-70 x+1000=0
x²-20x-50x+1000=0
x(x-20)-50(x-20)=0
(x-20)(x-50)=0
x=20,50
x=50(rejected)
x=20 m
Answer:
24 minutes
Step-by-step explanation:
Given
Ashley = 12 minutes
Becky = 8 minutes
Required
Determine when they will be at the same point again
To do this, we simply determine the least common factor of both.
Ashley = 12, 24, 36, 48....
Becky = 8, 16, 24, 32........
From above, the least common factor is 24
<em>Hence, both of them will be at the starting point in 24 minutes</em>
Answer:
okay gonna assume the dilation scale factor is 0.5, not -0.5
A' is at point (2,1)
B' is at point (3,1)
C' is at point (3,2)
D' is at point (2,3)
Step-by-step explanation:
make all of the sides of the model smaller by multiplying by 0.5. Then keep point A' where point A is because the center of the dilation is at point A.
