Answer:
(b) (6, 0)
Step-by-step explanation:
You are given the value of x. Substitute that in the other equation and find the value of y.
-3x +14y = -18
We know x=6 from the second given equation, so ...
-3(6) +14y = -18
Add 18 to both sides
14y = 0
Divide by 14
y = 0
Then the solution is ...
(x, y) = (6, 0)
Step-by-step explanation:
|2b - 9| = |b - 6|
|2b - b| = |-6 + 9|
|b| = |3|
b = 3

Answer:
a = 40°
Step-by-step explanation:
I. When total angle is 180 or half of circle
Find a or missing angle by
180 = 50 + 90 + x
180 - 140 = x
x = 40º
That makes a is 40º
Hope that help :)
Answer:
1. b. 2. a. 3. a.
Step-by-step explanation:
1. (f + g)x = f(x) + g(x)
= x^2 + 2x + 4
(f + g)(-1) = (f + g)(x) where x = 1 so it is
(-1)^2 + 2(-1) + 4
= 1 - 2 + 4
= 3.
2. We find (f o g)(x) by replacing the x in f(x) by g(x):
= √(x + 1) and
(f o g)(3) = √(3 + 1)
= √4
= 2.
3. (f/g) c = f(x) / g(x)
= (x - 3)/(x + 1)
The domain is the values of x which give real values of (f/g).
x cannot be - 1 because the denominator x + 1 = -1+1 = 0 and dividing by zero is undefined. So x can be all real values of x except x = -1.
The domain is (-∞, -1) U (-1, ∞)
