So for this one all you have to do is use the formular
Z*k=x
30k=8
K=4/15
Then when x=4
4/15x=4
So x=15
Answer: y = -5*x + b
Step-by-step explanation:
A line is written as:
y = a*x + b
where a is the slope and b is the y-intercept.
IIf we have a line that passes through the points (x1, y1) and (x2, y2) then the slope of the line is:
a = (y2 - y1)/(x2 - x1)
In this case we can see that the line passes through the points:
(0, 2) and (1, - 3)
Then the slope is:
a = (-3 - 2)/(1 - 0) = -5
Then our line is:
y = -5*x + b
And when x = 0, y = 2 then:
y = 2 = -5*0 + b
2 = b
Our line is:
y = -5*x + b
Based on the advertisement seen by Dazuri, the cost of each soccer ball is $22.50
<h3>How to find the cost?</h3>
The advertisement says that the original cost of the ball is $30 but there is a 25% discount.
The price of each soccer ball is therefore reduced by the 25% discount on the ball.
The amount that each soccer ball costs is therefore:
= 30 - ( 30 x 25%)
= 30 - 7.5
= $22.50
Rest of the question is:
Soccer balls on sale at a 25% discount. Prices go back to $30 in a week. Don't miss out.
