Slope intercept form:
y=mx+b
Where:
m= slope
b= y-intercept
For: y=1/2x-2
slope = 1/2
b= -2
To graph it we have to look at the y-intercept.(-2) It means that the line crosses the y axis at y=-2.
looking at the slope, we know that slope = rise (y) / run (x). 1/2
For every 2 units along the x-axis (to the right) the line goes up by 1 unit.
Since inequality has a y> the line is not included in the solution, so it's a dashed line, where the solution is above the line.
Answer:
(12,1.625)
Step-by-step explanation:
According to the given statement:
Cost of gas per gallon = $6
Cost of diesel per gallon = $8
Cost of x gallon gas = 6x
Cost of y gallon diesel = 8y
You have at most $85 to spend on fuel
Therefore the equation we get is:
6x+8y≤85
You must purchase at least 12 gallons of gas for your car
x≥12
Plot the graph and you get possible solutions:
(12,1.625)..

Answer:
$60745
Step-by-step explanation:
2,5÷100×2200
=55
55+2200
=2255
therefore 63000-2255
= $60 745
