Do distributive property
3 - 2x - 8 = 13
Combine like terms
-5 - 2x = 13
Add 5 to both sides
-2x = 18
Divide by -2
You would get x = -9

The independent variable in the relationship is the Number of Months and should be placed on the x-axis

The dependent variable in the relationship is the Number of Fish and should be placed on the y-axis

Step-by-step explanation:

Let us explain the independent and dependent variables of a relation

The independent variable is the input of the relation

The dependent variable is the output of the relation
The values of dependent variables depend on the values of independent variables
When the relation represented graphically the independent variable placed on the x-axis and the dependent variable placed on the y-axis

The table:

→ Number of Months: 0 : 1 : 2 : 3 : 4

→ Number of Fish : 1,024 : 1,280 : 1600 : 2,000 : 2,500

Let us check is their any constant ratio between the consecutive values of the number of fish

∵ 1,280 ÷ 1,024 = 1.25

∵ 1,600 ÷ 1.280 = 1.25

∵ 2,000 ÷ 1,600 = 1.25

∵ 2,500 ÷ 2,000 = 1.25

∴ The table represent an exponential function, where the input

is the number of months and the output is the number of fish

∵ The input is independent variable

∴ The independent variable is the number of months

∵ The output is the dependent variable

∴ The dependent variable is the number of fish

∵ The independent variable is placed on the x-axis

∴ The number of months should be place on the x-axis

∵ The dependent variable is placed on the y-axis

∴ The number of fish should be place on the y-axis

The independent variable in the relationship is the Number of Months and should be placed on the x-axis

The dependent variable in the relationship is the Number of Fish and should be placed on the y-axis

A box office sells balcony seats, ground-level seats, and VIP passes for shows on tour. The table shows the numbers of each type

Lana71 [14]

Answer:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Step-by-step explanation:

Let the price of one Balcony seat = $ $x$

Let the price of one Ground level seat = $ $y$

Let the price of one VIP seat = $ $z$

As per the given table:

$135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)$

Multiplying (1) with 2 and subtracting (2) from it:

$120x+290y=32100 \\12x+29y=3210..... (4)$

Subtracting (3) from (1):

$5x+15y=1600\\x+3y=320 ....... (5)$

Multiply equation (5) with 12 and subtracting (4) from it:

$7y=630\\\Rightarrow y =\bold{90}$

By equation (5), putting value of $y$ :

$x=\bold{50}$

By equation (1), putting the values of $x, y:$

$135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}$

Therefore, the answers are:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180
