Y=x^2+2x
Btw the X^2 means x to the power of 2
Answer:

Step-by-step explanation:
To find the equation of a line using slope and a point, first use the slope to create the basic line using the slope and work from there.
For instance, the base equation here is

This line passes through the point (0, 0).
You can then plug in a value for x. In this case, use the value of 3, as it corresponds with your question.

A point on the line of y = 2x would thus be (3, 6).
To make the y-value equal -3, you must then subtract from the original equation. There are 9 units between 6 and -3, so you must subtract nine units in the equation. You should get this at the end:

Answer:
x=50
Step-by-step explanation:
You must work backwards to isolate and find the answer, first making an equation and setting the unknown number as a variable, x. The answer is then the isolated value of x.
x/2+8 = 33
x/2 = 33-8
x/2 = 25
x/2(2) = 25(2)
Answer:
5,000,000= 625000 this many tickets if there 8 $
Step-by-step explanation:
And the ticket is 8$
How you would solve it is you take the number of money and divide it by how much each of the tickets are then the finished product is how many you have to sell.
