bring the 7 over.

to do so you must subtract 7 from itself (canceling it out), then also subtract it from 8.

now you have -x=1.

divide -x by -x (or -1) which just gives you positive x.

do the same to the 1 on the other side, giving you

Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.

Step-by-step explanation:

Simplifying an expression involves breaking down the expression.

The true statement is: (a) Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.

The expression is given as:

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}}}[/tex]

Start by writing the numerator and the denominator, with a common denominator

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{\frac{5 -4a +12}{a - 3}}{\frac{2a - 6 + 1}{a - 3}}}[/tex]

Cancel out the denominators of both fractions (by dividing the numerators)

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{5 -4a +12}{2a - 6 + 1}}[/tex]

So, we have:

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{17 -4a }{2a - 5}}[/tex]

Hence, the correct option is (a).

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

The line parallel to y =
5/4x + 8 that passes through (−8, 0).

The equation of the line that passes through (−8, 0) is y = ???

Answers

Answer:

y = 5x/4 + 10

Step-by-step explanation:

If two lines are parallel, the slopes are equal

The equation of a straight line is y = mx + c

where m is slope and c is y-intercept

So in this case 5/4 is also the slope m of the second line

we can write the equation as;

y-y1 = m(x-x1)

y-0 = 5/4(x + 8)

y = 5x/4 + 10

Find the length of the shortest side ( rounded to 2DP) if the area of the rectangle is 28m^2

Answers

Answer:

4.39 to 2DP.

Step-by-step explanation:

x * (x - 2) =  28

x^2 - 2x = 28

Solving by completing the square:

(x - 1)^2 - 1 = 28

(x - 1)^2 = 29

x = +/-√29 + 1

x = 6.38516, -4.38516

x must be positive so it = 6.38516.

The shortest side = x - 2 = 4.385.

Write an equation of the line that passes through the points (-1,8) and (2,-4)

Answers

Answer:

y=mx+b

y=-4x +12 is your equation

m= yo

your slope

Step-by-step explanation:

Answer:

The equation of the line that passes through the points (-1,8) and (2,-4) is:

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

Step-by-step explanation:

Given the points

(-1,8)(2,-4)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:-4\right)[/tex]

[tex]m=\frac{-4-8}{2-\left(-1\right)}[/tex]

[tex]m=-4[/tex]

As the point-slope form of the line equation is

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

where m is the slope.

substituting the values m = -4 and the point (-1,8)

[tex]y-\(8\right=-4\left(x-\left(-1\right)\right)[/tex]

[tex]y-8 = -4(x+1)[/tex]

Add 8 to both sides

[tex]y-8+8=-4\left(x+1\right)+8[/tex]

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

Therefore, the equation of the line that passes through the points (-1,8) and (2,-4) is:

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

I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell?

Answers

You sold 15 cookies and 12 muffins.

c - cookies
m - muffins

c + m = 27

3c + 7m = 129

I don’t know how to explain how to do efficiently but I just plugged in numbers until it worked:

3(15) + 7(12) = 129

45 + 84 = 129

Answer:

You sold 15 cookies and 12 muffins

Step-by-step explanation:

So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7

You're also given that in total you made $129, and sold 27 items

Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.

3c + 7m = 129 (equation for amount of money made)c + m = 27 (equation for amount of items sold)

Now we can use the second equation to find m:

c + m = 27

m = 27 - c

Not we can substitute m into the first equation to find c:

3c + 7m = 129                  

3c + 7(27-c) = 129            [substitute m for (27-c)]

3c + 189 -7c = 129           [distribute 7 into (27-c)]

-4c + 189 = 129                [combine like terms]

-4c = -60                          [subtract 189 from both sides]

c = 15                               [divide both sides by -4]

Now we can substitute c into the second equation to find m:

c + m = 27

15 + m = 27

m = 12

Write the question, in slope-intercept form, for the line shown in the graph below:

Can some one pls help me in this math problem?

Answers

Answer:

The question, in the slope-intercept form will be:

[tex]y=1(x)+0[/tex]

Step-by-step explanation:

Taking the two points on the line to find the slope

(0, 0)

(4, 4)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)[/tex]

[tex]m=\frac{4-0}{4-0}[/tex]

[tex]m=1[/tex]

As the point-slope form is

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

where m is the slope

substituting the values m = 1 and the point (0, 0)

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

[tex]y-0=1(x-0)[/tex]

[tex]y=x[/tex]

As the slope-intercept form is

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

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

so writing the equation in slope-intercept form

[tex]y=x[/tex]

[tex]y=1(x)+0[/tex]

Therefore, the question, in the slope-intercept form will be:

[tex]y=1(x)+0[/tex]
