Domain: x is greater than or equal to 7
Range: y is greater than or equal to 9
Answer: x = 3
Step-by-step explanation: 10 x + 20 = 5x + 35
10 x + 20 - 5x = 35
5x = 35 - 20
5x = 15
x = 3
Answer:
Step-by-step explanation:
Easiest way would be to substitute points into the given equations and plot your answers.
E.g. if you substitute points into your first equation you get:
If x = 0, y = -4(0) +2 = 2
If x = 1, y = -4(1) +2 = -2
If x = -1, y = -4(-1) +2 = 6
Etc.
Second equation:
If x = 0, y= -(0) -1 = -1
If x = 1, y = -1 -1 = -2
If x = -1, y = -(-1) -1 = 0
Pretty much just plug in values for x into the equations to find y.
Once you have your points, draw a line :)
Where the two lines intercept would be the solution.
Answer:
see below
Step-by-step explanation:
A horizontal line has the same y value and is a constant y value
y = -5
A vertical line has the same x value and is a constant x value
x = -6
