Y = -2x2 + 10 y = -2x – 2

34kurt

Answer:

x = 6

y = - 14

Step-by-step explanation:

$\left \{y=-2x2 + 10y} \atop {y=-2x -2}} \right.$

-2x × 2 + 10 = - 2x - 2
x = 6
y = -2 × 6 - 2 = - 14

You go to an arcade and purchase a card with game credits. After playing 5 games you have 33 credits left. You play 4 more games

Amanda [17]

Answer:

$y=-3x+48$

Step-by-step explanation:

We will use slope-intercept form of equation to write our equation. The equation of a line in slope-intercept form is: $y=mx+b$ , where m= Slope of the line, b= y-intercept.

To write the equation that represents the number of credits y on the cards after x games, we will find slope of our line.

We have been given that after playing 5 games we have 33 credits left. We play 4 more games and we have 21 credits left. So our points will be (5,33) and (9,21).

Let us substitute coordinates of our both given points in slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$ ,
