BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?
Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8             12

------   = -----------

x+4          2x+1


using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10

30 pts for this one.... (only if you give a reasonable answer no BS)
Keith_Richards [23]

Answer:

  1. y = 3000x + 40000
  2. a) the base salary of the salesperson
  3. a) the commission per subscription

Step-by-step explanation:

Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].

Best of Luck!
