Answer:

[tex]x = \frac{12}{7}\ books[/tex]

Step-by-step explanation:

Given

[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]

Required

Number of books in 1 week

Represent the number of books in 1 week with x.

So, we have:

[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]

[tex]x = 1\ week[/tex]

Cross Multiply

[tex]x * 1\frac{3}{4} = 3 * 1[/tex]

[tex]x * 1\frac{3}{4} = 3[/tex]

Convert fraction to improper fraction

[tex]x * \frac{7}{4} = 3[/tex]

Multiply through by [tex]\frac{4}{7}[/tex]

[tex]x * \frac{7}{4}*\frac{4}{7} = 3 * \frac{4}{7}[/tex]

[tex]x = 3 * \frac{4}{7}[/tex]

[tex]x = \frac{12}{7}\ books[/tex]

Hence: 12/7 books were read in a week

Answer:

The equation of the line passing through the given point that is perpendicular to the  given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]

Step-by-step explanation:

Write the equation of the line passing through the given point that is perpendicular to the  given line.

y = - 4x + 7: (4,2)

The equation of required line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept

Finding slope:

When two lines are perpendicular their slopes are opposite reciprocal of each other. [tex]m_1=-\frac{1}{m_2}[/tex]

So, slope of given line = -4 ( Comparing with [tex]y=mx+b[/tex] m = -4)

Now, slope of required line will be: m =1/4 (Opposite reciprocal)

Finding y-intercept

y-intercept can be found using m = 1/4 and point (4,2)

[tex]y=mx+b\\2=\frac{1}{4}(4)+b\\2=b[/tex]

So, we get b = 2

Now, Equation of line

Equation of line having slope m = 1/4 and y-intercept b = 2 is:

[tex]y=mx+b\\y=\frac{1}{4}x+2[/tex]

So, the equation of the line passing through the given point that is perpendicular to the  given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]

Answer:

The equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the line

3x - 4y = 7

writing in the slope-intercept form

4y = 3x - 7

dividing both sides by 4

4y/4 = 3/4x - 7/4

y = 3/4x - 7/4

Now, comparing with the slope-intercept form of the line equation

y = 3/4x - 7/4

The slope of the line m = 3/4

We know that parallel lines have the same slopes.

Therefore, the slope of the parallel line is: 3/4

now we have,

The point (-4, -2)

The slope m of parallel line = 3/4

Given the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting (-4, -2) and m = 3/4 in the point-slope form of line equation

[tex]\:y-\left(-2\right)=\frac{3}{4}\left(x-\left(-4\right)\right)[/tex]

[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]

Thus, the equation in the point-slope form of the line equation is:

[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]

Simplifying the equation

[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]

Subtract 3 from both sides

[tex]y+2-2=\frac{3}{4}\left(x+4\right)-2[/tex]

[tex]y=\frac{3}{4}x+1[/tex]

Multiplying the equation by 4

[tex]4y = 3x + 4[/tex]

[tex]3x - 4y = -4[/tex]

Therefore, the equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:

The equations that represent the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) are: y + 2 = 3/4x + 3 and y = 3/4x + 1

If two lines are parallel, the slope (m), in their equation in slope-intercept form (y = mx + b) would be the same.

Rewrite the equation, 3x - 4y = 7 in slope-intercept form

-4y = -3x + 7

y = -3y/-4 + 7/-4

y = 3/4y - 7/4

The slope (m) is 3/4, therefore, the slope of the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) would be: m = 3/4.

Substitute (a, b) = (-4, -2) and m = 3/4 into y - b = m(x - a)

y -(-2) = 3/4(x - (-4))

y + 2 = 3/4(x + 4)

y + 2 = 3/4x + 3

y = 3/4x + 3 - 2

y = 3/4x + 1

The equations that represent the line are:

y + 2 = 3/4x + 3 and y = 3/4x + 1

Answer:

It will take 20 hours for Mrs. Reed to catch up with Mr. Reed

Step-by-step explanation:

Given that:

Mr. Reed leaves 5 hours early.

Speed of Mr. Reed = 40 mph

Distance covered in 5 hours = 40 * 5 = 200 miles

Let,

h be the number of hours and D be the total distance.

D = 40h + 200

Speed of Mrs. Reed = 50 mph

D = 50h

For catching up, both distances will be same

D = D

50h = 40h + 200

50h - 40h = 200

10h = 200

Dividing both sides by 10

[tex]\frac{10h}{10}=\frac{200}{10}\\h=20[/tex]

Therefore,

It will take 20 hours for Mrs. Reed to catch up with Mr. Reed

Answer:

Amount of Chris' commission = $6800

Step-by-step explanation:

Given that:

Value of the house sold by Chris = $85,000

Percent of Chris' commission = 8%

Amount of Chris' commission = 8% of 85000

Amount of commission = [tex]\frac{8}{100}*85000[/tex]

Commission = 0.08 * 85000

Commission = $6800

Hence,

Amount of Chris' commission = $6800

Answer:

[tex]\displaystyle y=\frac{1}{3}x-6[/tex]

Step-by-step explanation:

Dilation of a Line

Given a line that passes through points A(-3,-4) and B(-6,-5). We'll apply a dilation with a scale factor of 2 centered at the origin by multiplying each coordinate by 2. The points map to:

A'(-6,-8) and B'(-12,-10)

Now we find the equation of the line passing through A' and B'.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Substituting:

[tex]\displaystyle y+8=\frac{-10+8}{-12+6}(x+6)[/tex]

[tex]\displaystyle y+8=\frac{-2}{-6}(x+6)[/tex]

[tex]\displaystyle y+8=\frac{1}{3}(x+6)[/tex]

Operating:

[tex]\displaystyle y=\frac{1}{3}x+\frac{1}{3}*6-8[/tex]

[tex]\displaystyle y=\frac{1}{3}x+2-8[/tex]

[tex]\boxed{\displaystyle y=\frac{1}{3}x-6}[/tex]

Written in interval notation, it is ...

  [-1, 1] . . . . using square brackets to indicate the end values are included

__

Curly brackets { } are used to delimit a set. That is {-1, 1} means the y-values consist only of -1 or 1 and nothing else. Obviously, that is not the case here.

Answer:

a(y-1)/1+y

Step-by-step explanation:

Given the expression y = a + p/a-p

yo are to make P the subject of the formula:

Step 1:  Cross multiply

y = a + p/a-p

y(a-p) = a+p

Step 2: open the bracket

ya - yp = a+ p

Step 3: Collect the like terms

ya - a  = p+ yp

ya - a= p(1+y)

a(y-1) = p(1+y)

Step 4: Divide both sides by 1+y

a(y-1)/1+y = p(1+y)/1+y

a(y-1)/1+y = p

p =a(y-1)/1+y

Hence the required solution is p = a(y-1)/1+y
