Each calendar will sell for 5 each. Write an equation to model the total income, y, for selling x calendars
OleMash [197]

Answer:

y = 5x

Step-by-step explanation:

If each calendar, <em>x</em>,  sells for $5 each, you would multiply 5·x because $5 is how much you earn per calender. Therefore, your total income would be 5 times the number of calendars you sell, or in equation "language", y = 5x

Match the function with its value<br> f(x)= x2-3x+3<br> g(x)= 2x2-1 <br><br> f(z^2)= .....
Elis [28]
There's nothing here to 'match' it with.

f(x) = x^2 - 3x + 3

f(z^2) = (z^2)^2 - 3z^2 + 3

f(z^2) = z^4 - 3z^2 + 3

<em><u>g(x)</u></em> is only there to confuse you.
Apparently it was successful.
