The domain of f(x) = √(x - 7) +9 is x ≥ 7 and the range of f(x) = √(x - 7) +9 is y ≥ 9
<h3>How to determine the domain and the range?</h3>
The function is given as:
f(x) = √(x - 7) +9
Set the radicand greater than or equal to 0
x - 7 ≥ 0
Add 7 to both sides
x ≥ 7
The above represents the domain
Set the radicand to 0
f(x) = 0 +9
So, we have
f(x) = 9
This represents the minimum value of the range.
So, the range is y ≥ 9
Hence, the domain of f(x) = √(x - 7) +9 is x ≥ 7 and the range of f(x) = √(x - 7) +9 is y ≥ 9

Answer:
40
Step-by-step explanation:
90 + 4x - 8 + 4x + 2 = 180
= 8x = 96
= x = 12
m < a = 4(12)-8 = 40
Answer:
miles
You have to walk more miles to get to the shoe store.
Step-by-step explanation:
So first, we have to convert the to a fraction that has a denominator of 8, which we are going to multiply 2 on both top & bottom. Equation-
* =
And then, the house to shoe store is miles as we know from the question. We subtract the distance by , because that is how much we've walked already. And we know that when we are subtracting fraction, we need to make sure the denominators are the same and we ONLY subtract the numerator. So the equation would be like this-
- =
And we got the answer- miles
