A line contains the points (-12, -60) and (60, -42).
Ivahew [28]

The slope of the line in simplified form is \frac{1}{4}

Step-by-step explanation:

The slope of a line which contains points (x_{1},y_{1}) and (x_{2},y_{2})

is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

The given is:

1. Point (-12 , -60) lies on the line

2. Point (60 , -42) lies on the line

We need to find the slope of the line

∵ (x_{1},y_{1}) = (-12 , -60)

∵ (x_{2},y_{2}) = (60 , -42)

- Substitute these values in the rule

∴ m=\frac{-42-(-60)}{60-(-12)}

∴ m=\frac{-42+60}{60+12}

∴ m=\frac{18}{72}

∴ m=\frac{1}{4}

The slope of the line in simplified form is \frac{1}{4}

The table shows the profit from a school book fair based on the number of books sold. What is the rate of change for the functio
dsp73

You are given a table

\begin{array}{cc}\text{Number of books sold} & \text{Profit}\\100 & \$50\\250 & \$275\\300 & \$350\\350 & \$450\end{array}

The rate of change for the function represented in the table can be calculated using the formula

\dfrac{y_{i+1}-y_i}{x_{i+1}-x_i},

where i=1,2,3.

1. When i=1,

\dfrac{y_2-y_2}{x_2-x_1}=\dfrac{275-50}{250-100}=\dfrac{225}{150}=1.5

2. When i=2,

\dfrac{y_3-y_2}{x_3-x_2}=\dfrac{350-275}{300-250}=\dfrac{75}{50}=1.5

3. When i=3,

\dfrac{y_4-y_3}{x_4-x_3}=\dfrac{425-350}{350-300}=\dfrac{75}{50}=1.5

Then the rate of change is $1.5

Answer: correct choice is D.

There are 6 gray keys for every 11 black keys. Also, the number of black keys is 2 less than twice the number of gray keys. Use
emmainna [20.7K]

\text{ Answer: There are }12\text{ gray keys.}\\\\\text{ there are }22\text{ black keys.}

Explanation:

Since we have given that

There are 6 gray keys for every 11 black keys .

So, the ratio will be 6:11

Let the number of gray keys be 6x

Let the number of black keys be 11x

Now, according to question,

11x=2\times 2x-2\\\\11x=12x-2\\\\11x-12x=-2\\\\-x=-2\\\\x=2

so,

\text{ there are }6x=6\times 2=12\text{ gray keys.}\\\\\text{ there are }11x=11\times 2=22\text{ black keys.}

1.75/2 = 0.875 kg per loaf.

For 8 loaves, the amount of flour needed is 
8*0.875 = 7 kg

Answer: 7 kg of flour is needed for 8 loaves.
