Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>to find:</h3>
<h3>let's solve:</h3>
A-5B=2x+3-5(x²-5x+1)
- distribute -5 to the parentheses:2x+3-5x²+25x-5
- rewrite:-5x²+2x+25x-5+3
- combine like terms:-5x²+27x-2
and
we are done
Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x) ≤ 95
<h3>What are the domain and range?</h3>
The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.
Domain is therefore:
-18 ≤ x ≤ 10
The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.
Range is:
16 ≤ f(x) ≤ 95

Hope this helps though I believe I have 3 and 7 incorrect since I'm not good at writing expressions....
Answer:
A = 2700 ft^2
Step-by-step explanation:
The area is given by
A = l*w
Convert yds to ft
1 yd = 3 ft
90 yds = 90 *3 = 270
A = 10 * 270
A = 2700 ft^2
