Answer:
$8
Step-by-step explanation:
Firstly, Let us identify the variables in the functions.
The function states that for every n ball, the price is $0.80. Plus the $5.50.
Now that we know what the function stands for, we can substitute 10 into n, and remove the entrance fee of $5.50.
P=0.80n
This gives us $8, which means the price for 10 balls not including the entrance fee is $8.
Use the distance formula for the 2 points and then halve the answer
Answer:
y = -5x + 39
Step-by-step explanation:
Plug either ordered pair into the Point-Slope Formula FIRST, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>then convert to Slope-Intercept Form by moving whichever term is nearest to <em>y</em><em>,</em><em> </em>over to the right side of the equivalence symbol to get the above answer.
