The given information is
When she adds 2 to both sides, the equation
Subtracting 3x to both sides
So the equation has exactly one solution which is
Answer:
A system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
Step-by-step explanation:
Let the number of
Haircuts = x
Hair dyes = y
Hence:
Alexandra finds that she can give:
3 haircuts and 2 hair dyes in 315 minutes.
3x + 2y = 315..... Equation 1
Giving 2 haircuts and 4 hair dyes takes 450 minutes
2x + 4y = 450...... Equation 2
Therefore:
a system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
Answer:
Step-by-step explanation:
The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.
The slope of the line perpendicular to the one shown below will be because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
