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: 7/8 is bigger and 1/3 is smaller

Step-by-step explanation:

0.875 is the decimal version of 7/8 and 0.333333333... is the decimal verision  of 1/3.  The difference is that 7/8's is bigger.  If you want to compare fraction-wise you have to make them have the same denominator by doing that you have to mulitpy 7/8's by 3 which is 21/24 and you have to do the same thing to 1/3 so you have to mulitpy 1/3 by 8 to get 24 which makes 1/3 into 8/24.  So now you got 8/24 and 21/24.  Which one is bigger?  Yep, 21/24.  Please give me brainliest.  I do well explaining it.  

The difference of the given fractions is 13/24.

Subtracting fractions include the subtraction of two or more fractions with the same or different denominators. Like fractions can be subtracted directly but for unlike fractions we need to make the denominators same first and then subtract them.

Given that, 7/8-1/3.

LCM of the denominators 8 and 3 is 24.

Now, make the denominators same for both the fractions, that is

7/8 = 21/24 and 1/3 = 8/24

Thus, 7/8-1/3=21/24-8/24

= 13/24

Therefore, the difference of the fractions is 13/24.

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]

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]

[tex]x = -\frac{12}{5}[/tex]

Step-by-step explanation:

To solve the equation, isolate x. Whatever you do to isolate x one on side, you must do to the other.  

1) Multiply both sides by 9 to get rid of the fractions.  

[tex]\frac{21-4x}{9} +\frac{8x+15}{3} = 2 \\21-4x + 3(8x + 15) =18 \\[/tex]

2) Distribute the 3 to 8x and 15. Then, combine like terms.

[tex]21-4x + 24x + 45 = 18 \\66 + 20x = 18[/tex]

3) Move the 66 to the other side, subtracting 18 by 66, then divide each side by 20 to finally isolate x.

[tex]20x = -48\\x = -\frac{48}{20} \\x =- \frac{12}{5}[/tex]

Thus, [tex]x = -\frac{12}{5}[/tex].

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
