OleMash [197]3 years ago
3 0

Answer:  

John ate 20%  of the cookies

Explanation:

Given:  

total cookies John bought= 15 cookies,

Number of cookies john ate = 3 cookies

To Find:

Percentage of cookies John ate. =?

Solution:

We know that the formula of finding the percentage of any thing which is given as

percentage=\frac{(given value)}{(total value)}\times100

So according to question,  we have given value = 3

And Total value = 15

Now we will put these values in the formula of percentage to find out the % of cookies that he ate.

percentage=\frac{3}{15}\times100=20\%

Hence , he ate 20% of cookies

Find the slope of the line through the points (−3, 6) and (2, 6).
Elden [556K]

Answer:

There wouldn't be a slope. It would be 0/5

Step-by-step explanation:

\frac{6-6}{2+3}

6 - 6 = 0

2 + 3 = 5

0/5 isn't a slope.

The table below represents a function. Which of the following equations could be its function rule?
worty [1.4K]

Answer:

y=2x-2 is the required equation.

Therefore, the second option is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation of a linear function is given by

y=mx+b

where m is the slope and b is the y-intercept

Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)

m=\frac{0-\left(-2\right)}{1-0}

m=2

substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.

y=mx+b

-2 = 2(0)+b

-2=0+b

b=-2

Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function

y=mx+b

y=2x+(-2)

y=2x-2

Thus, y=2x-2 is the required equation.

Therefore, the second option is true.
