Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
g(x) = -x + 2
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in function values: (f + g)(x) = x + 3 - x + 2
- [Subtraction] Combine like terms (x): (f + g)(x) = 3 + 2
- Add: (f + g)(x) = 5
Answer:
17.91÷5=3.582
then
3.582×9=32.238
or 32.2 or just 32
Step-by-step explanation:
when you see something like this all you have to do is divide the two number then with that number just multiply.
Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
Answer:
y = -3x + 1
Step-by-step explanation:
y = -3x + 1
y = -3 . -2 + 1
= 6 + 1
y = 7
y = -3x + 1
y = -3 . 2 + 1
= -6 + 1
= -5
y = -3x + 1
= -3 . 4 + 1
= -12 + 1
= -11
so, it should be y = -3x + 1

Using the simple interest formula, [ i=prt ],
y=360*0.03*x
