Answer:

3)

Step-by-step explanation:

An equation is linear if equal changes in x produce equal changes in y.

Let's look at each choice.

1)

A decrease of 10% per year. That means each year, the value of the car is 0.9 times the value of the previous year.

For example, if the original value was $10,000, after 1 year, it is worth 0.9 * $10,000 = $9,000. In 1 year it lost $1,000. In the next year, its value is now 0.9 * $9,000. The value at the end of the 2nd year is $8,100. In the second year, it lost $900 in value. In one period of 1 year it lost $1000 in value. In another equal period of 1 year, it lost $900 in value. A change of 1 year in time produces different changes in loss of value, so it is not linear.

2)

Here, the number doubles every year. Let's say it starts with 100 fish. After 5 years, it has 200 fish. In a change of 5 years in x, the change in y is 100. In the next 5 years, it goes from 200 fish to 400 fish. The change in the second period of 5 years is 200. We see that a change of 5 years can produce a change of 100 fish, but another change of 5 years can produce a change is 100 fish. Since for equal changes in x, the changes in y are not all equal, this is not linear.

3)

Here for every change of 1 day in x, the change in y is 2 liters. Each change of 1 in x always produces a change of 2 in y. This is linear.

4)

Each 2 hours, the amount of caffeine is 2/3 of what it was before. This is similar to the choice 1), and it is not linear.

Select the correct answer. Consider the function f(x) = 3x and the function g, which is shown below. How will the graph of g dif
Sloan [31]

Answer:

The graph of g is the graph of f shifted up by 3 units.

Step-by-step explanation:

Consider the graph of a function r with real numbers k and h.

Transformation Effect

r(x) + k shifts the graph up k units

r(x) - k shifts the graph down k units

r(x + h) shifts the graph to the left h units

r(x - h) shifts the graph to the right h units

It is given that g(x) = f(x) + 3. Therefore, the graph of g is the graph of f shifted up by 3 units.

I think this a linear function. The graph has a constant flow of going up. In other words, it is linear.

ANYONE up???????????????????????????and can i get help with this
Mashcka [7]

Answer:

here's the solution : -

=》2x - 3y = -29

=》x + 6y = 23

=》x = 23 - 6y

now, plugging the value of x in equation 1, we get : -

=》2x - 3y = -29

=》2 (23 - 6y) - 3y = - 29

=》46 - 12y - 3y = -29

=》-15y = -29 - 46

=》y = -75 ÷ -15

=》y = 5

now, plugging the value of y as 5 in equation 2

=》x + 6y = 23

=》x + (6 × 5.2) = 23

=》x = 23 - 30

=》x = - 7
