Answer:
The solution will be "x = 2 and x = -1".
Step-by-step explanation:
The given equation is:
⇒ 
On solving "
", we get
⇒ 
As we know, if the base are same then their powers will be added together.
⇒ 
...(equation 1)
⇒ 
...(equation 2)
From equation 1, we get
⇒ 
⇒ 
From equation 2, we get
⇒ 
⇒ 
So that the correct answer will be "x = 2" and "x = -1".
Answer:
7/8
Step-by-step explanation:
1. Make 1 9/8 into an improper fraction
1 = 8/8
8/8 + 9/8 = 17/8
2. Subtract
17/8 - 11/8 = 7/8
Answer:
Given point (5,-12) falls into IV quadrant
<u>The right triangle with legs of 5 and -12, and hypotenuse is:</u>
- √5² + (-12)² = √25+144 = √169 = 13
<u>Value of sinθ, cosθ, and tanθ:</u>
- sin θ = -12/13
- cos θ = 5/13
- tan θ = -12/5
Answer:
A) x ≠ 0
B) x ≠ 3
Step-by-step explanation:
The domain is all the possible values of x such that f(x) exists.
A) f(x) = (x + 5) / x
x can't be 0 (can't divide by 0), so the domain of x is all values other than 0.
You can write this in interval notation:
(-∞, 0)⋃(0, ∞)
Inequality notation:
x < 0 or x > 0
Or simply:
x ≠ 0
B) f(x) = 1 / (x - 3)
x can't be 3 (can't divide by 0), so the domain of x is all values other than 3.
(-∞, 3)⋃(3, ∞)
x < 3 or x > 3
x ≠ 3
The place value of 7 in this is 700
