weeeeeb [17]

Answer:

Step-by-step explanation:

5*50 + 10y = 800

250+10y=800

10y=550

y=55

The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total? 60. The soccer team collected $800 at a car wash fundraiser.

5x + 10*50 = 800  ====>  5x + 500 = 800  ====>  5x = 800-500 = 300  ====>  x = 300%2F5 = 60

Y=5x^2-8x-12 <br><br><br> linear , exponential , or quadratic and why
Assoli18 [71]

Answer:

Quadratic

Step-by-step explanation:

This is a quadratic equation because it's in the form of y=ax^2+bx+c

If it were linear, the graph would be a straight line and wouldn't contain a second degree term

If it were exponential there would be a growth or decay factor
