Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)

Answer:
1.21 kilograms
Step-by-step explanation:
Let y represent the mass of the empty basket, and x represent the mass of each ball
Create a system of equations:
3x + y = 3.64
5x + y = 5.26
Solve by elimination by multiplying the top equation by -1
-3x - y = -3.64
5x + y = 5.26
Add them together, then solve for x:
2x = 1.62
x = 0.81
Plug this back into one of the equations and solve for y:
3x + y = 3.64
3(0.81) + y = 3.64
2.43 + y = 3.64
y = 1.21
So, the mass of the empty basket is 1.21 kilograms
Answer:
x>1 the bottom graph
Step-by-step explanation:
(18x - 9 > 9) and (2x - 4 > -10)
Do the first inequality first
18x - 9 >9
Add 9 to each side
18x - 9+9 > 9+9
18x> 18
Divide each side by 18
18x/18 > 18/18
x >1
Then the second inequality
(2x - 4 > -10)
Add 4 to each side
2x-4+4>-10+4
2x>-6
Divide each side by 2
2x/2 >-6/2
x>-3
Since this is an and
x>1 and x>-3
We take the more restrictive
x>1
