An investment firm invested in two companies last year. they invested $11,000 in company a and made a profit of 24% . they invested $14,000 in company b and made a profit of 15% . answer the questions below. do not do any rounding.
(a) what was the investment firm's total profit? $
(b) what was the percent profit for their total investment? %

(a) $4,740  (b) 18.96%

Step-by-step explanation:

An investment firm invested in two companies.

In company A  they invested $11,000 and made a profit of 24%.

In company B they invested $14,000 and made a profit of 15%.

(a) We will calculate the firm's total profit :

In Company A profit = 24% of 11,000

                                  = 0.24 × 11,000

                                  = $2,640

In Company B profit = 15% of 14,000

                                  = 0.15 × 14,000

                                  = $2,100

Total profit = $2,640 + $2,100 = $4,740

(b) We will calculate the percent profit for their total investment.

Total investment = $25,000

Total profit           = $4,740

Percentage     =

                       = 18.96%

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
