Answer:
1
Step-by-step explanation:
Anything divided by itself is always 1.
Answer & Step-by-step explanation:
In this problem, we are given two functions.
<em>s(x) = 2x + 1</em>
<em>r(x) = -x² + 3x</em>
We are asked to find the difference between s(x) and r(x).
<em>(2x + 1) - (-x² + 3x)</em>
Distribute the negative to the second parentheses.
<em>2x + 1 + x² - 3x</em>
Combine like terms and put the equation in standard form. This means the exponents should be in descending order.
<em>x² - x + 1</em>
So, (s - r)(x) equals x² - x + 1

Answer:
Graph A
Step-by-step explanation:
≤ (less than or equal to) or ≥ (greater than or equal to) have solid lines because it can be equal to.
< (less than) or > (greater than) have dashed lines because it cannot be equal to.
Less than ( < or ≤ ) = shade under.
Greater than ( > or ≥ ) = shade over.
