Yes, it is a rational number.
You basically just switch it around and subtract the fractions
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
(-7,2)(4,6)
slope = (y2 - y1) / (x2 - x1)
slope = (6 - 2) / (4 - (-7) = 4 / (4 + 7) = 4/11
Answer:
x=0
Step-by-step explanation:
−6+5x+14=8
(5x)+(−6+14)=8(Combine Like Terms)
5x+8=8
5x+8=8
Step 2: Subtract 8 from both sides.
5x+8−8=8−8
5x=0
Step 3: Divide both sides by 5.
5x
5
=
0
5
