Which equation has no solution?

Mathematics

Alina [70]3 years ago

Answer:

<em>The equation which has no solution is 5 + 2(3 + 2x) = x + 3(x + 1) . </em>(see below for work)

Step-by-step explanation:

4(x + 3) + 2x = 6(x + 2)

4x + 12 + 2x = 6(x + 12)

4x + 2x = 6x

6x = 6x

x ∈ ℝ

5 + 2(3 + 2x) = x + 3(x + 1)

5 + 6 + 4x = x + 3(x + 3)

11 + 4x = x + 3x + 3

11 + 4x = 4x + 3

11 = 3

x ∈ ∅ (CORRECT ANSWER)

5(x + 3) + x = 4(x + 3) + 3

5x + 15 + x = 4x + 12 + 3

6x + 15 = 4x + 12 + 3

6x + 15 = 4x + 15

6x = 4x

6x - 4x = 0

2x = 0

x = 0

4 + 6(2 + x) = 2(3x + 8)

4 + 12 + 6x = 6x + 16

4 ÷ 12 = 16

16 = 16

x ∈ ℝ

Hope this helps! :)

djyliett [7]

Answer:

Option A:

Number of seats

Step-by-step explanation:

A discrete quantitative variable is a variable that can be enumerated. This means that they are in units in which numbers can be assigned to and can be counted.

The number of seats present in the car can be counted. This feature can also be evaluated based on its numeral value, rather than its quality. In a simple form, the buyers feel that the more the number of seats present in the car, the more people it can carry. Hence, the family would love to buy a car with a good number of seats in it.

The other features in the options are rather continuous, qualitative, or boolean. Some of them are continuous because they cannot be counted e.g fuel efficiency. The others such as the presence of a sunroof can be seen as a boolean variable. (it can either be true or false)

Type of the transmission is a qualitative variable
