Answer:
they show parralel line and perpendicular line
if the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
the x and y intercept are different
two solutions
Answer:
p = $15d - (7,000 + 0.84d)
Step-by-step explanation:
In this question, we are asked to given an equation that will represent the profit Dion makes when he has made a total of d deliveries.
We proceed as follows:
To calculate the profit, we need to subtract the cost price from the selling price.
Let’s start with the cost price. This refers to the total amount of money that is used to prepare the goods for sales and also spent on that cause. He charges $0.42 for gasoline per trip. This means it is a total of $0.84 for each delivery. This is because two trips will make a delivery. Total number of money spent on gasoline on deliveries is thus 0.84 * d = 0.84d. Now, we add the cost of Motorcycle he rides to be $7,000. The total money spent is thus $7000 + $0.84d
His selling price is simply the number of deliveries he has made multiplied by the amount of money he charges per trip. This is same as 15 * d= $15d
Profit is thus ; p = $15d - (7,000 + 0.84d)
Substitute the variable terms with the coordinates and the equation is
3=1/3(5)+b
solve for b
True, if a points works in both equations of a linear system, then that point is the solution.
