The given number is not a solution of the equation i.e. the number is an inequality

<h3>How to determine the solution?</h3>

The equation is given as:

3x- 4 = 10

The number is given as:

This means that

x = 5

Substitute x = 5 in 3x- 4 = 10

3 * 5- 4 = 10

Evaluate the product

15- 4 = 10

Evaluate the difference

11 = 10

The above equation is not true i.e. the equation is actually an inequality

Hence, the given number is not a solution of the equation i.e. the number is an inequality

Answer:

The equation is: y = 15·x

Step-by-step explanation:

It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.

Consider the table below.

Number of Hours: 1 3 6 10

Number of Bicycles Produced: 15 45 90 150

Compute the ratio of number of bicycles produced and number of hours for every data above as follows:

$\text{1 hour}=\frac{15}{1}=15:1\\\\\text{3 hour}=\frac{45}{3}=\frac{15}{1}=15:1\\\\\text{6 hour}=\frac{90}{6}=\frac{15}{1}=15:1\\\\\text{10 hour}=\frac{150}{10}=\frac{15}{1}=15:1$

The ratio of the number of bicycles produced and number of hours is same for every data value.

Thus, the relationship between the number of bicycles produced and number of hours is proportional.

The equation for the relationship is:

y = 15·x

y = number of bicycles produced

x = number of hours

Dovator [93]

Answer:

The answer is C.

Step-by-step explanation:

y = kx → e =

h → e = 7.5h

The independent variable is hours worked, h, and the dependent variable is total earnings, e. The independent variable is the input value of a function. The dependent variable is the output value of a function.

kakasveta [241]

Or, if your money is earning a 5 percent interest rate, you'll double it in 14.4 years (72 divided by 5 equals 14.4). If your money is earning a measly 1 percent interest rate, it will take you—yep, you guessed it—a whopping 72 years to double it.
