Answer number 8 please

Answer:

x = 9/5 = 1 4/5

Step-by-step explanation:

5x - 6 = 3

    +6   +6

(add positive 6 to the negative 6 = - 6 + 6 = 0, and to the answer = 3 = 3 + 6 = 9)

5x = 9

÷5   ÷5

x = 9/5 (improper fraction)

= 1 4/5 (mixed numeral)

Hello.

First, let's add 6 to both sides:

[tex]\tt{5x-6+6=3+6}[/tex]

[tex]\tt{5x=9}[/tex]

The next step is to divide both sides by 5:

[tex]\tt{x=\displaystyle\frac{9}{5}[/tex] (Improper fraction)

[tex]\tt{x=\displaystyle1\frac{4}{5}[/tex] (Mixed number)

I hope it helps.

Have a great day.

They paid sales tax on a customer which cost $196.00​ is 75 %.

We have given that,

At a store, 3 cents on every dollar spent is charged as sales tax.

A sales tax is a tax paid to a governing body for the sales of certain goods and services

0.3 multiplied by $196.00

0.3 *196=58.8

$58.8 as sales tax.

Adding that to the $196 dollars

Answer:

He needs to read 14 pages on Thursday to finish the book

Answer:

14 ft.

Step-by-step explanation:

First, we will assign variables to each value. If height is h, and base is b, then

1/2bh = 112 and h=b+2.

We will use substitution in this system of equations. first, we will isolate the b in bh/2=112. To do this we will multiply both sides by 2 to isolate the variables, so bh=224. Then, to isolate just one variable, in this case, b, we will divide 224 by h, getting us b=224/h.

Then, we will substitute b for this value in h+2=b, leaving us with h+2=224/h

Then isolate the variable. h will equal either -14 or 16. Because this is a geometric shape, the value of its sides cannot be negative, so it has a height of 16.

Then, plug this into the second equation. If the height is 2 ft more than the base, then the base will be 14 ft.

The solution of the considered system of equation is represented by: Option C: (1,3) and (4,0)

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)

For the considered case, the system of equations given to us is:

[tex]y = x^2 - 6x + 8\\y = -x + 4[/tex]

Plotting both's graph and finding the common points on both's graph, we get the common points as:

(1,3) and (4,0)

These points satisfy both the equations simultaneously.

Therefore, the solution of the considered system of equation is represented by: Option C: (1,3) and (4,0)

Step-by-step explanation:

Answer:

He should have divided by 4, not 6....

Step-by-step explanation:

Just did the lesson

Abdul have done error by dividing with 6 instead of 5, So Abdul should have divided by 5, not 6 is correct option.

The area of Rectangle is length times of width.

According to the information provided, the initial dimensions of the pool are a rectangle with length 24 feet and width 15 feet.

The corresponding dimensions in the drawing are a rectangle with length 4 feet and width 3.75 feet.

Therefore, the scale factor for the length is:

24/4 = 6

And the scale factor for the width is:

15 feet / 3.75 feet = 4

Abdul wants to fit the pool into a smaller space, so he needs to find the corresponding dimensions of the pool in the drawing that has a length of 20 feet.

To maintain the same scale, he needs to apply the same scale factor to the new length.

Thus, the new length in the drawing is:

20/6 = 3.33 feet

Similarly, he needs to apply the same scale factor to the new width to maintain the same scale.

Thus, the new width in the drawing is:

18.75/4 = 4.69 feet

Now, let's check Abdul's work:

24/6×6/20=4/3

Left side is not equal to right side.

Abdul should have divided by 5, not 6.

Hence, Abdul have done error by dividing with 6 instead of 5, So Abdul should have divided by 5, not 6 is correct option.

The step that Omar should proceed with is given by: Option D: Omar should factor out a negative from one of the groups so the binomials will be the same.

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomials.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

The polynomial that Omar is dealing with is:

[tex]3x^3 - 15x^2 -4x + 20[/tex]

We see that 3 times 5 = 15 and 4 times 5 = 20, so trying in that way:

[tex]3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) + 4(-x + 5)[/tex]

Taking out a negative factor from second term would make the binomials same, after which we can take that common out, as shown below:

[tex]3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) + 4(-x + 5) \\3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) -4(x-5) \\3x^3 - 15x^2 -4x + 20 = (x-5)(3x^2-4)[/tex]

It successfully got factored, thus not a polynomial.

Thus,the step that Omar should proceed with is given by: Option D: Omar should factor out a negative from one of the groups so the binomials will be the same.

Answer: 62

Step-by-step explanation:

We'll need the slope formula which is

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\[/tex]

We subtract the y values together, and divide that over the difference in the x values when subtracted in the same order.

Let's find the slope of line DE

[tex]D = (x_1,y_1) = (6,1) \text{ and } E = (x_2,y_2) = (2,3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{3 - 1}{2 - 6}\\\\m = \frac{2}{-4}\\\\m = -\frac{1}{2}\\\\[/tex]

The slope of line DE is -1/2.

Next, compute the slope of line EF

[tex]E = (x_1,y_1) = (2,3) \text{ and } F = (x_2,y_2) = (-1,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-3 - 3}{-1 - 2}\\\\m = \frac{-6}{-3}\\\\m = 2\\\\[/tex]

The slope of line EF is 2.

Lastly, compute the slope of line FD

[tex]F = (x_1,y_1) = (-1,-3) \text{ and } D = (x_2,y_2) = (6,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - (-3)}{6 - (-1)}\\\\m = \frac{1 + 3}{6 + 1}\\\\m = \frac{4}{7}\\\\[/tex]

The slope of line FD is 4/7.

--------------------------

To recap everything so far, we found the following:

The product of the first two slopes gets us (-1/2)*(2) = -1 showing that DE is perpendicular to EF.

Perpendicular slopes multiply to -1 as long as neither line is vertical nor horizontal.

Since DE is perpendicular to EF, this proves we have a 90 degree angle at point E.

Therefore triangle DEF is a right triangle.
