Answer:
x=2 y,=3
(2,3)
Step-by-step explanation:
3x - 5y = -9
x + 2y = 8
We will use elimination. Multiply the second equation by -3
-3(x + 2y) = 8*-3
-3x -6y = -24
Add this to the first equation
3x - 5y = -9
-3x -6y = -24
-----------------------
0 - 11y = -33
Divide each side by -11
-11y/-11 = -33/-11
y =3
Now substitute into the second equation to find x
x+ 2y = 8
x+2(3) =8
x+6 =8
Subtract 6 from each side
x+6-6=8-6
x=2
Answer: 3x-5y=-9 is simplified to y=3/5x+9/5
x+2y=8 is simplified to y=-1/2x+4

Answer:
six raised to the one twelfth power
Step-by-step explanation:
The cubed root of 6/the fourth root of 6 equals (6^1/3)/(6^1/4)
6^((1/3)-(1/4))
6^((4-3)/12)
6^1/12
You would want to subtract 18 from 45. Your answer would be y=27.
0.25 km is the answer.
1km = 1000m
x = 250
x = 250/1000
x = 0.25
40/5=8
The pitcher allowed 8 runs in 40 innings.
Answer:
m = -10
Step-by-step explanation:
m = y2 - y1 / x2 - x1
m = 60-50 / -2 - -1
m = 10/ -1
m = -10
