HELP PLEASEE The linear function m = 3a represents the amount m in dollars) of money a customer pays after buying a phone apps. Each customer can buy a maximum of three apps.

1. Identify the independent and dependent variables.
2. Is the domain discrete or continuous? Explain.

1. The independent variable is a and the dependent variable is m

2. The domain is discrete

Step-by-step explanation:

let us explain the difference between discrete or continuous domains

Discrete domain: It is a set of input values that consists of only certain numbers in an interval.

Continuous domain: It is a set of input values that consists of all numbers in an interval.

In the question

m = 3a, where

m is the amount of money m in dollars

Each customer can buy a maximum of three apps

1.

∵ m is depended on the value of 3a

∴ m is the dependent variable ⇒ (output)

∴ a is the independent variable ⇒ (input)

∴ The independent variable is a and the dependent variable is m

2.

∵ The domain the input values

∴ Each customer can buy a maximum of three apps

→ That means it is a certain numbers

∴ The domain is discrete

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
