Y=-.5x+3
Explanation: Move the x to the other side by subtracting it from both sides, you end up with 10y=30-5x then you divide 10 from both sides and you end up with y=-.5x+3
Answer:
x=2 and 2/3
Step-by-step explanation:
LINE A
y-intercept : 3
x-intercept: 3
Rate of change: x (because 3/3 equals 1 and 1 times x is the same as x by itself)
Line B
y-intercept: 2
x intercept: -2
rate of change : x (because 1/1 is 1 and 1 times x is the same as x by itself)
Line C
y-intercept: -4
x intercept: 2
rate of change: 2
Line A: Equation F
Line B: Equation D
Line C: Equation E
Extra Notes:
y=mx + b is the slope intercept equation.
M is the slope
B is the y intercept
X and Y are the coordinates
To find slope, you can always use y2-y1/x2-x1 or even determine the slope on the graph by using rise over run and simplifying when possible.
(Please check my method to see if the answers are correct)
The period of the function is 2pi
Since he has an annual salary, the salary stays the same, making it the y intercept.
As for 250, it goes to every car he sells, making it the slope
S = y + mc (y = y intercept, m = slope)
Plug in the values to see
Solution: A. 45,000 + 250C
