Answer:
y = 1.2x + 770
Step-by-step explanation:
y = m*x + b
Equation One
y = mx + b
1370 = m*500 + b
Equation Two
y = mx + b
1730 = m*800 + b
Solution
1730 = 800*m + b
1370 = 500*m + b Subtract. The b's cancel
360 = 300 * m Divide both sides by 300
360/300 = m
1.2 = m
Now use the second equation to solve for b
y = 1730
x = 800
1730 = 1.2*800 + b
1730 = 960 + b Subtract 960 from both sides
b = 770

Answer:
x = 2
Step-by-step explanation:
Given
3x + 8x - 2 = 20 , that is
11x - 2 = 20 ( add 2 to both sides )
11x = 22 ( divide both sides by 11 )
x = 2
Answer:
x = 10 and y = 5
Step-by-step explanation:
We are given:
the system of equations
-4x+11y=15... Equation 1
x=2y....... Equation 2
We substitute 2y for x in Equation 1
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
y = 15/3
y = 5
Solving for x
2y = x
2(5) = x
10 = x
Therefore,
x = 10 and y = 5
