Answer:
(17,0) and (-2,19)
Step-by-step explanation:
First, find the gradient of AB, which is 1. As CD is perpendicular, its gradient will be -1. The equation of CD will be y=17-x. The x intercept is where y=0. So, that will give you x=17. When x=-2, y=19. It proves the equation right.
Answer:
337
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total number of boxes bought = 8
Total amount spent = 2,696
So, we can calculate the cost of 1 box by using following formula
Cost of 1 box = Total amount spent ÷ Total number of boxes bought
By putting the value, we get
Cost of 1 box = 2,696 ÷ 8
= 337
Hence, the cost of 1 box is 337.
