4 0

Answer:

Rate of change is increase of 51 followers per year.

Step-by-step explanation:

Given:

Number of followers in 2012 = 74

Number of followers in 2015 = 227

Therefore, increase in followers = 227 - 74 = 153

Duration for the change = 2015 - 2012 = 3 years

Rate of change of followers is given as:

\textrm{Rate of change}=\frac{Increase}{Duration}=\frac{153}{3}=51

Therefore, rate of change is increase of 51 followers per year.

Three bags of chips costs m cents. At this rate, what is the cost, in cents, of one bag of chips?
olya-2409 [2.1K]

Answer: m/3 cents

Step-by-step explanation:

Hi, to answer this question we have to divide the total cost of the chips (m) by the number of bags of chips (3).

Mathematically speaking:

Cost of one bag chip: m/3 cents

Since the total cost is represented by a variable, the individual cost is an expression.

If we replace the value of m by a number we will obtain the result as a number.

Feel free to ask for more if needed or if you did not understand something.

How do I answer this question
seraphim [82]
We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.

There are about 2 pounds in one kilogram.

Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.

2 * 2 = 4

So, the answer to this question is 4 pounds.

It should be d. , Because if you take the equation 3x+y=9, and make it slope intercept form, it would be y= -3x+9. -3 is the slope, and 9 is the y intercept. D is the answer.

Write the equation of the line that goes through each set of points (-1,6),(3-2)
Mariana [72]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-1, 6) and (3, -2). Substitute:

m=\dfrac{-2-6}{3-(-1)}=\dfrac{-8}{4}=-2\\\\y-6=-2(x-(-1))\\\\y-6=-2(x+1)\qquad\text{use distributive property}\\\\y-6=-2x-2\qquad\text{add 6 to both sides}\\\\y=-2x+4\qquad\text{add 2x to both sides}\\\\2x+y=4

<h3>Answer:</h3><h3>y - 6 = -2(x + 1)    <em>point-slope form</em></h3><h3>y = -2x + 4      <em>slope-intercept form</em></h3><h3>2x + y = 4     <em>standard form</em></h3>
