Hi there!

A dependent variable is one that is changed, when the independent variable changes.

For example, if we wanted to calculate how many dollars we've earned in a given amount of time, time would be the independant variable, because it is a constant and is not affected by how much many we earn. The amount of money we earned is directly affected by the independent variable, time.

Your answer is b.

Hope I helped!

Be sure to leave a "Brainliest" if I was helpful. Or not lol. I really don't care tbh XD

Answer:- Option b. is the right answer. A dependent variable is manipulated by changes to the independent variable.


Explanation:-

In mathematical modelling or scientific research  a variable is defined as a term that has a quantity that varies. There are two kinds of variables:- 1) dependent variables 2) independent variables.

A independent variable can be change by the experimenter to check the effects on dependent variables which is observed by the him in a scientific experiment.

Thus, A dependent variable is manipulated by changes to the independent variable.

The graph of a polynomial S(x) = (2x - 3)(x – 4)(x+3) has x-intercepts at 3.x values.
dezoksy [38]

Answer:

Step-by-step explanation:

x-intercepts exist where y is equal to 0. Where y is equal to 0 is where the graph goes through the x-axis. Our x-intercepts are (2x-3), (x + 3), and (x-4). Again, since x-intercepts exist where y = 0, then by the Zero Product Property, 2x - 3 = 0, x - 4 = 0, and x + 3 = 0. In the first x-intercept:

2x - 3 = 0 and

2x = 3 so

x = 3/2

In the second:

x - 4 = 0 so

x = 4

In the third:

x + 3 = 0 so

x = -3

So the x-intercepts in the correct order are x = 3/2, 4, -3

Consider the line y=-5/4x-5 find the equation of the line that is parallel to this line and passes through the point (-8,4)
gayaneshka [121]

Answer:

y = -5/4x + 6

Step-by-step explanation:

Since the line we are supposed to find is parallel to y = -5/4x - 5 that means they are going to have the same slope. The line we are looking for is of the following type: y = -5/4 x + b

Since it passes through the point (-8,4):

4 = -5/4 * (-8) + b <=>

4 = -2 + b <=>

4 + 2 = b <=>

b = 6

Hence the line is going to be: y = -5/4x + 6
