Answer:

Change

Step-by-step explanation:

Here there are two variables a and b.

a is causing variable b.

In other words, a is an independent variable which can take any values, and b takes values depending on the value of a.

Examples are: b=ma+k or b =2a^2 etc.

Whenever we change a there is a change in b.

But it should be noted when there is a change in b, there is a change in a also.

However, normally a is changed first and b is derived from a.

Hence the statement

In order to show that variable a causes variable b, you need to change_____ variable

I can't seem to find the answer for this I'm pretty sure it's non linear

Nata [24]

Answer:

(d) No. Slope is not constant.

Step-by-step explanation:

You want to know if the given graph shows a linear function.

<h3>Linear function</h3>

The graph of a linear function is a straight line. The points on the graph shown do not form a straight line, so the function is nonlinear.

<h3>Rate of change</h3>

The rate of change of a function is the ratio of "rise" to "run" between two points in the graph. This ratio is also called the "slope." For a straight line, the rate of change (slope) is constant. That is, a linear function has a constant rate of change.

If the function is nonlinear, its rate of change is not constant. The converse is also true: if the slope is not constant, the function is nonlinear.

How to do question 4?

Nutka1998 [239]

Marie states that any integer greater than 4 will always get an even number of factors.

This can be proven wrong by (for example) 12.

12 has these factors:

1 x 12
2 x 6
3 x 4

12 has an ODD number of factor pairs.

Another example is 28.

28:
1 x 28
2 x 14
4 x 7

28 has an odd number of factor pairs.

I hope this helps!

(11a - 2b +7c) - (3a - 9b + 5c)

ivolga24 [154]

<h3>Answer: 8a + 7b + 2c</h3>

Work Shown:

(11a - 2b + 7c) - (3a - 9b + 5c)

11a - 2b + 7c - 3a + 9b - 5c ... see note below

(11a-3a) + (-2b+9b) + (7c-5c)

8a + 7b + 2c

note: don't forget to distribute the negative through to every term inside the parenthesis
