Answer:

s+a=150

3s+8a=1000

a=-s+150

3s-8s+1200=1000

-5s=-200

s=40

a=110

40 student and 110 adult tickets were sold

Which is a quadratic function?

ryzh [129]

Answer: $f(x)=5x^2-4x+5$

Step-by-step explanation:

A quadratic function is as following; $ax^2+bx+c$

Notice that it cannot be $f(x)=0x^2-4x+7$ because if you solve; $0x^2=0$ which eliminates the $x^2$ .
