Answer:

solution,

$- 2 = \frac{x - 17}{2} \: \\ - 2 \times 2 = x - 17 \\ - 4 = x - 17 \\ - x = - 17 + 4 \\ - x = - 13 \\ x = 13 \\ \\ 7 = \frac{y + 17}{2} \\ 14 = y + 17 \\ - y = 17 - 14 \\ - y = 3 \\ y = - 3$

Therefore,

V=(13,-3)

Hope this helps...

The expression 148 – 24d gives the number of pizzas a store has in stock, where d is the number of days. How many pizzas will th

Feliz [49]

Explanation

A function is defined as a relation between a set of inputs having one output each,in this case our independent variable is the number of days( d) and the dependent variable would be the number of pizzas

Step 1

let the function

$\begin{gathered} P=148-24d \\ where\text{ P is the number of pizzas } \\ and\text{ d is the number of days} \end{gathered}$

therefore, to know the number of pizzas are in the stock after 5 days we need to evaluate the equation for d=3

$\begin{gathered} P=148-24d \\ let\text{ d=5 and evaluate} \\ P=148-24(5) \\ P=148-120=28 \\ P=28 \end{gathered}$

so, after five day there willbe 28 pizzas in stock

I hope this helpsyou
