Enter the equation of the line in slope-intercept form.

ad-work [718]

Answer:

$y = \frac{7}{4}x +14$

Step-by-step explanation:

Given

$y = \frac{7}{4}x + 4$

Required

Determine the equation of line that passes through (-8,0) and parallel to $y = \frac{7}{4}x + 4$

Parallel lines have the same slope.

In $y = \frac{7}{4}x + 4$

The slope, m is

$m = \frac{7}{4}$

because the general form of a linear equation is:

$y = mx + b$

Where

$m = slope$

So, by comparison:

$m = \frac{7}{4}$

Next, is to determine the equation of line through (-8,0)

This is calculated using:

$y - y_1 = m(x - x_1)$

Where

$m = \frac{7}{4}$

$(x_1,y_1) = (-8,0)$

So, we have:

$y - 0 = \frac{7}{4}(x -(-8))$

$y - 0 = \frac{7}{4}(x +8)$

$y - 0 = \frac{7}{4}x +\frac{7}{4}*8$

$y - 0 = \frac{7}{4}x +7*2$

$y - 0 = \frac{7}{4}x +14$

$y = \frac{7}{4}x +14$

Mr. Clark traveled 456.4 km in 14 days.

xeze [42]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

<h3><u>Distance travelled each day is</u> : </h3>

32.6 km

<h3><u>Explanation</u> : </h3>

Distance travelled in 14 days is : 456.4 km

And if he travels same Distance each day, so let the Distance travelled on each day be x

According to question ~

$\qquad \sf \dashrightarrow \: 14 \times x = 456.4$

$\qquad \sf \dashrightarrow \: x = 456.4 \div 14$

$\qquad \sf \dashrightarrow x = \: 32.6 \: \: km$

So, he travels 32.6 km per day

The number of vehicles passing through a bank drive-up line during each 15-minute period was recorded. The results are shown bel

Answer:

The correct answer is: Option D: 26 vehicles

Step-by-step explanation:

Median is the middle value of a sorted data set.

The formula for median depends on the number of values in the dataset.

First of all we have to arrange the given data in order

So,

14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34

Counting the values in the dataset

n = 20

As the number of values is even, the formula for median will be

$M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)$

Putting the values

$M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)$

The 10th value in dataset is 26 and 11th is also 26 so

$M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26$

Hence,

The correct answer is: Option D: 26 vehicles
