Answer:
I do not see all the graphs but it would be the reverse of what is shown for A. graph. The tickets sold to total income would have to be a 1:4 ratio where every 4 dollar leap in the y-axis is a one point (1 unit change in x).
Step-by-step explanation:
Answer:

Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
Answer:
x-2x-35
Step-by-step explanation:
-5 and 7
x=-5
x=7
x+5=0
x-7=0
Put them in bracket.
(x+5)(x-7)
Expanding the bracket
x(x-7)+5(x-7)
x-7x+5x-35
x-2x-35
Answer:
-1
Step-by-step explanation:
Using a graphing calculator, it is convenient to find where the difference between the two sides of the equation is zero. The associated real root is ...
x = -1
The given linear system is:

The question is asking to solve using elimination. When eliminating, you can either eliminate x or y. In this system, y is much easier to eliminate. The y variable in both equations are 7y. To eliminate, one of them has to be negative, so multiply one of the equations by -1.
I will be multiplying the second equation by -1.

Rewrite the system:

Subtract:


Lastly, you need to leave the variable x alone. The variable is currently -6x or -6 times x. To remove it, you need to do the opposite of it, which is dividing by -6.


Now that you have the value of x, substitute it into one of the equations to find y. I will be substituting it into the first equation.

Open the parentheses and multiply:

Move 5 to the other side to leave the variable alone:

You will be subtracting since you're "removing" it by doing the opposite of it.

Lastly, divide both sides by 7 to leave y alone.



The answer is (1, 4).
