the cost is proportional to the number of people because a constant value 9.50 exists where each measure of the number of people multiplied by this constant gives the corresponding measure in y
Summarizing the problem, there are three terms that you have to deal with: purchasing cost, down payment and loan. So, you would expect that the answer would contain these quantities. Among them, the unknown is the purchasing cost, therefore, we denote this as x.
<span>Based on the statement, "The amount of the loan is the purchase cost minus the down payment", we can formulate an equation for this.
Amount of Loan = x - Down payment
This will be our working equation. Moving on, the down payment was mentioned to be equal to </span>$1500. The lean received is equal to <span>$2600. Substituting these values to the working equation, we can now determine the value of x.
2600 = x - 1500
Solving for x by transposing it to one side,
x = 2600-1500
x = $1,100
Therefore, the purchasing cost of the car is $1,100.</span>
Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)
