A movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total c

Anastasy [175]

Answer:

$y=5x+15$

Step-by-step explanation:

Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs $(x_1,y_1)\rightarrow(5,40)$ and $(x_2,y_2)\rightarrow(12,75)$ :

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5$

Thus, our equation so far is $y=5x+b$ . Next, we need to find our y-intercept, $b$ , which represents our flat fee. We do so by using one of our original given ordered pairs:

$y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b$

Therefore, our final equation for the function is $y=5x+15$

Together, teammates Pedro and Ricky got 2673 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each

ioda

Answer:

Pedro got 1520 base hits and Ricky got 1243.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of base hits that Pedro got.

y is the number of base hits that Ricky got.

Pedro and Ricky got 2673 base hits last season.

This means that $x + y = 2763$

Pedro had 277 more hits than Ricky.

This means that $x = y + 277$

Replacing in the first equation

$x + y = 2763$

$y + 277 + y = 2763$

$2y = 2486$

$y = \frac{2486}{2}$

$y = 1243$

$x = y + 277 = 1243 + 277 = 1520$

Pedro got 1520 base hits and Ricky got 1243.
