Answer:
Step-by-step explanation:
<u>Mark</u>
- Initial amount - $200
- Earning - $20*j
- Saving is: S = 20j + 200
<u>Ryan</u>
- Initial amount - $350
- Earning - $15*j
- Saving is: S = 15j + 350
<u>If they get same saving, then the equations will be equal:</u>
- 20j + 200 = 15j + 350
- 20j - 15j = 350 - 200
- 5j = 150
- j = 150/5
- j = 30
The answer is 30 mowing jobs
Answer:
The range would be all real numbers
Step-by-step explanation:
In order to find (wor)(x), we need to start with the w(x) equation and then input the r(x) equation for every x in the w(x) equation.
w(x) = x - 2
(wor)(x) = (2 - x^2) - 2
(wor)(x) = -x^2
Given this equation, we know that x can be all real numbers
Answer:
(f - g)(x) = 9x + 1
Step-by-step explanation:
Step 1: Write out functions
f(x) = 3x + 10x = 13x
g(x) = 4x - 1
Step 2: Find (f - g)(x)
(f - g)(x) = 13x - (4x - 1)
(f - g)(x) = 13x - 4x + 1
(f - g)(x) = 9x + 1

Answer:
Area = 38.1 ft² (nearest tenth)
Step-by-step explanation:
Use sine rule for area of a triangle:
Area = (1/2)ab sin(C)
= (1/2)bc sin(A)
= (1/2) x 11 x 8 x sin(60)
= 22√3
= 38.1 ft² (nearest tenth)
