Answer:
Step-by-step explanation:
Answer:
Slope = -1/2
Y-Intercept = 2
Equation: Y=-1/2x+2
Step-by-step explanation:
Graph goes 2 units up at y=2, that's your y-intercept. From there, plot your second point by moving 1 down and 2 to the right from the y-intercept, landing on the point (2,1) to get your slope, written as -1/2.
Answer:
m=-8/3
Step-by-step explanation:
1/m+4=3/4
cross multiply over the equal sign
1×4=3(m+4)
4=3m+12
combine the like terms
4-12=3m
-8=3m
divide by 3
-8/3=3m/3
m=-8/3
A.12 grapes, 23 plums
Step-by-step explanation:
1. solve all the equations by multiplying each number by how much each item is worth
2. A: 290 =(12× 5)+(10×23)
B: 100 =(10×5)+(5×10)
C:125 =(5×5)+(10×10)
D:235 =(23×5)+(12×10)
Answer:
1/8
Step-by-step explanation:
<u>Solving in steps:</u>
- x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
- x/8(x-y) +y/8*(-(x-y))
- x/8(x-y) - y/8(x-y) =
- (x -y)/8(x-y) =
- 1/8
Answer is 1/8
