Answer:
3.51 (round to the nearest hundreds)
Step-by-step explanation:
PART A
slope of the line passing through AC : (6-1)/(1-2) = 5/-1 = -5
equation of the line passing through B and perpendicular to AC:
y-3 = 1/5(x-3)
y-3 = 1/5x -3/5
y = 1/5 x - 3/5 + 3
y = 1/5 x + (-3+15)/5
y = 1/5 x + 12/5
PART B
line that passes through the points A and C
y-1 = -5(x-2)
y = -5x+10 + 1
y = -5x + 11
Interception of the lines
y = 1/5x + 12/5
y = -5x + 11
-5x + 11 = 1/5x + 12/5
-25x +55 = x + 12
26x = 43
x = 43/26
y = -5(43/26) + 11
y= -215/26 + 11
y = (-215+286)/26 = 71/26
D (1.65, 2.73)
PART C
AC = = 5,09902
BD = = 1,376735
PART D
AREA = (5,09902 * 1.376735)/2 = 3,509999
Answer:
Part A)
Part B) see the explanation
Step-by-step explanation:
Part A) Write an inequality that will represent the amount of sales Ollie will need in order to cover his monthly expenses
Let
x ----> the amount of sales monthly
Remember that
we know that
The fixed amount of $2,700 plus the commission of 12% on all of his sales for the month must be greater than or equal to $5,400
so
The inequality that represent this problem is
Part B) Find the solution and describe what the graph would look like on a number line
we have
Solve for x
subtract 2,700 both sides
Divide by 0.12 both sides
The minimum amount of sales needed to cover his monthly expenses is $22,500
In a number line the solution is the shaded area at right of x=22,500 (closed circle)
see the attached figure to better understand the problem
