What is the y-value for the solution to the system of equations below? 10x + 8y = -24 5x+6y = 2​

Y = -1.4

The simplest way to find the answer is to cancel out the x - values. Set both equations equal to zero.
10x + 8y + 24 = 0
5x - 6y - 2 = 0
Multiple the second equation by -2 so the x terms cancel out when you add them together.
10x + 8y + 24 = 0
-10x + 12y + 4 = 0

20y + 28 = 0
20y = -28
Y = -1.4

A. To answer this question, we must consider two inequalities. The first inequality we will construct is regarding the number of tickets sold with respect to capacity. The theater cannot exceed the allotted 200 seats, so this would indicate we would use a less than or equal to inequality. The inequality we would construct to illustrate this using adult and child tickets is x + y <= 200.
The second inequality we will construct is based upon the ticket prices set and the theater’s goal. The problem indicates the theater wants to sell “at least $1,500 worth of tickets...” To create the inequality here, we will create it as follows: 12.5x + 6.25y >= 1,500.
To find the intersection point, we must isolate y. In order to do this, move x to the other side of both inequalities. Inequality 2 can be simplified to y >= -12.5x / 6.25 + 1,500 / 6.25. Graph and identify the solution from there.

D. Lamar's teacher extended the graph as shown below and asked Lamar to write the function for the graph shown below using f(x)
Ainat [17]
You can read the slope of the line directly from the graph:

m = rise/run = 1/1 = 1.  Also easily visible is the y-intercept, b = 1.

Thus, this linear function has the equation f(x) = x + 1.
