Answer:
x=3
y=13
Step-by-step explanation:
okay so what that means is that the two equations are y=-x+16 and y=3x+4
so y+x=16
y-3x=4
so 4x=12 so x=3
y=13 is the solution
Answer: she printed 200 programs
Step-by-step explanation:
Let x represent the number of programs that were printed.
The printing cost was $0.32 per program. This means that the total cost of printing x programs would be 0.32 × x = $0.32x
They were priced at $0.50 each. This means that the total revenue from selling x programs is 0.5 × x = $0.5x
Taylor sold all but 50 programs. It means that the number of programs sold is
x - 50 and the total revenue from the number of programs sold is 0.5(x - 50)
Revenue - cost = profit
Taylor made a small profit of $11. It means that
0.5(x - 50) - 0.32x= 11
0.5x - 25 - 0.32x = 11
0.5x - 0.32x = 11 + 25
0.18x = 36
x = 36/0.18
x = 200
Parallel lines have the same slope.
We have the general form of line. Transform to the slope-intercept form:
m - slope, b - y-intercept
<em>subtract 2x from both sides</em>
<em>add 10 to both sides</em>
<em>divide both sides by 7</em>
Therefore we have: 
.
The line passes through the point (2, 2). Substitute the coordinates of the point to the equation of a line:
<em>add 
to both sides</em>
<em>multiply both sides by 7</em>
<em>subtract 7y from both sides</em>
<em>change the signs</em>
