<span>A) 2x=96-14y
B) 9x=40-14y
Rearranging algebraically
</span>
A) 2x <span>+14y = 96
B) 9x </span><span>+14y = 40</span>

Multiplying equation A by -1
A) -2x <span>-14y = -96 Then adding it to equation B
B) 9x </span><span>+14y = 40
7x = -56
x = -8

</span><span>2*-8 = 96 -14y
-16 -96 = -14y
-112 = -14y
y = 8

A 5000 seat theater has tickets for sale at 26 and 40. How many tickets should be sold at each price for a sellout performance t
slavikrds [6]

Answer:

The number of tickets for sale at $26 should be 3300

The number of tickets for sale at $40 should be 1700

Step-by-step explanation:

Use 2 equations to represent the modifiers within the problem:

5000 = a + b \\ 153800 = 26a + 40b

Now you want to find the point at which the variables are changed to make both equations correct, this can be done by graphing and finding the intersection of both lines.

5000 = 3300 + 1700 \\ 153800 = 26(3300) + 40(1700)

13+x+195=13(x+15)...
LUCKY_DIMON [66]
First, let's expand the right side.  Now our equation is

13+x+195=13x+195

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right.  We get:

-12x=-13

And then we can make this

12x=13

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08

Rasek [7]
Answer:
slope = -9/2

Explanation:
The form of the slope-intercept equation is:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
y = -9/2 x

Comparing the given with the general form, we will find that:
m is the slope = -9/2
c is the y-intercept = 0

Hope this helps :)
