Answer:
(f - g)(x) = -x + 8
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 1
g(x) = 3x - 7
(f - g)(x) = f(x) - g(x)
<u>Step 2: Simplify</u>
- Set up: (f - g)(x) = (2x + 1) - (3x - 7)
- Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7
- Combine like terms: (f - g)(x) = -x + 8
Answer:
x= 15 so the c) is right
Step-by-step explanation:
We can do it like:
3(2x + 5) = 3x + 4x
or 6x + 15 = 7x
-6x+ 6x +15 = -6x+ 7x
or 15 = x
The solution is 15
Hope you understand it.
The slope intercept form is y=mx+b notice y's coefficient is 1
7y+5x=-15
subtracting 5x
7y=-5x-15
dividing by 7
y=(-5/7)x-(15/7)

Explanation
I don’t have one
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
