Answer:
x > - 4
Step-by-step explanation:
Given
7(x + 4) > 0 ← distribute left side
7x + 28 > 0 ( subtract 28 from both sides )
7x > - 28 ( divide both sides by 7 )
x > - 4
Considering their concepts, on the graph of a function, the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In a graph, the horizontal axis represents the input and the vertical axis represents the output, hence the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.

Answer:
1. A. 12a^2 + 8a + 4
2. C. 4xy+16x-4y^2-16y
3. C. 64q^6r^8s^4
4. A. -4x^4y^6
Step-by-step explanation:
48a^3 + 32a^2 + 16a / 4a = (48a^3) / 4a + (32a^2) / 4a + (16a) / 4a = 12a^2 + 8a + 4.
So, the answer is A. 12a^2 + 8a + 4.
(2x-2y)(2y+8) = 4xy - 4y^2 + 16x - 16y.
So, the answer is C. 4xy+16x-4y^2-16y.
(-8q^3 * r^4 * s^2)^2 = (-8)^2 * q^6 * r^8 * s^4 = 64q^6r^8s^4.
So, the answer is C. 64q^6r^8s^4.
-12x^8y^8 / 3x^4y^2 = (-12 / 3) * (x^(8 - 4)) * (y^(8 - 2)) = -4x^4y^6.
So, the answer is A. -4x^4y^6.
Hope this helps!
If we solve the left side of the given equation,
1/a + 1/b = 1/c
we get an answer of,
b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.
