Answer:
Step-by-step explanation:
7x -1 +6x -1 = 180, group like terms
7x+6x -1 -1 = 180, combine like terms
13x -2 = 180, add 2 to both sides
13x -2+2 = 180+2 , solve the additions
13x = 182, divide both sides by 13
13x/13 = 182/13, solve the divisions
x = 14

Original: $99.99
New: _________
Tax: 8.75
%Discount: 40%
Answer:
$68.74
Step-by-step explanation:
Original: $99.99
New: x
Tax: $8.75
Discount : 40%
Discounts are applied before tax.
40% of 99.99 = 0.40(99.99) = 39.996
99.99 - 39.996 = 59.994
Apply tax:
59.994 + 8.75 = 68.744 ≈ 68.74
-Chetan K
Answer: 68.74
Step-by-step explanation:

59.994 + 8.75= 68.744
Round
68.74
what’s the value of x
Answer:18
Step-by-step explanation:
a straight line is equal to 180
you already have part of the angle (162)
so then you subtract the two angles
180-162=18
Which type of data would be best displayed in a box plot?
Answer:C
Step-by-step explanation: option C, The number of votes received by each of four candidate can be best displayed in a box plot.
Explanation:
We need to find which type of data can be displayed in a box plot from the given options.
The box plot can used to show the shape of a distribution, the lower value , higher value , the central value, and its variability.
The graph shows how the values of the data are spread out .It is the distribution of numerical data. Box plot can be used to compare multiple groups .
So, the answer can be option C

State the domain in proper interval notation.
Answer:
-5 < x < -2
Step-by-step explanation:
domain is all the x values
interval notation can look something like this ? < x < ?
for this case -5 is the far edge of the domain and -2 is on the other side
so it would be -5 < x < -2

Kareem wanted to write an equation for his friend that has many solutions. Help him write an equation.
Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions
Step-by-step explanation: (x+2) = 0 only has one solution.
(x+2)*(x-4) = 0 has two solutions, -2 and 4
(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc
If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.
Rewrite the following equation in slope-intercept form. Y + 4=1/3(x-6)
Answer:
[tex]y=\dfrac{1}{3}x-6[/tex]
Step-by-step explanation:
Slope intercept form: y = mx + b
[tex]y + 4 = \dfrac{1}{3}(x -6)\\\\y + 4 = \dfrac{1}{3}x - \dfrac{1}{3}*6\\\\y + 4 =\dfrac{1}{3}x - 2\\\\y = \dfrac{1}{3}x - 2 - 4\\\\y =\dfrac{1}{3}x - 6[/tex]

Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
And then here is the answer
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places

Given the points (0, -1) and (6, 1), we need the following information to solve for the equation of the line:
We need the slope and the y-intercept.
Let (x1, y1) = (0, -1)
(x2, y2) = (6, 1)
Substitute these values into the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-1)}{6 - 0} = \frac{1 + 1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
Therefore, the slope (m) = 1/3.
Next, we need the y-intercept, (b), which is the point on the graph where it crosses the y-axis. It is also the value of the y-coordinate when its corresponding x-coordinate = 0.
Looking at one of the given points, (0, -1), this represents the y-intercept. Therefore, the y-intercept (b) = -1.
Now that we have our slope, m = 1/3, and y-intercept, b = -1, we can write our linear equation in slope-intercept form as:
y = 1/3x - 1

The FastForward Company balance sheet shows cash $5,000, accounts receivable $7,000, office equipment $3,000, and accounts payable $4,000. What is the amount of equity?
$15,000
$12,000
$19,000
The correct answer is option C) $12,000.
What is the amount of equity?
The equity of a company, or shareholders' equity, is the net difference between a company's total assets and its total liabilities. A company's equity is used in fundamental analysis to determine its net worth.
Given:
FastForward Company balance sheet shows cash = $5,000Accounts receivable = $7,000Office equipment = $3,000Accounts payable = $4,000.Total equity = 5000 + 7000 + 4000 - 3000
= $12000
What is an equity example?
Equity is the ownership of any asset after any liabilities associated with the asset are cleared. For example, if you own a car worth $25,000, but you owe $10,000 on that vehicle, the car represents $15,000 equity. It is the value or interest of the most junior class of investors in assets.

Question 9. The Angles (3 + 5x) and (x + 15) are forming linear pair, so
3 + 5x + x + 15 = 1806x + 18 = 1806x = 162x = 27°Question 10. Angle 58° + Angle (2x + 4) = 90, so
58 + 2x + 4 = 9062 +2x = 902x = 28x = 14°Question 11. 5x = 70°
x = 70 ÷ 5x = 14°Question 12. Angle 106° and Angle (2x +4) forms linear pair, so
106 + 2x + 4 = 180110 + 2x = 1802x = 70x = 35°Answer:
9. [tex]x=27[/tex]
10. [tex]x=14[/tex]
11. [tex]x=14[/tex]
12. [tex]x=35[/tex]
Step-by-step explanation:
9. [tex]3+5x+x+15=6x+18[/tex]
==>> [tex]6x+18=180[/tex]; subtract 18 from 180 giving you 162, and finally 162 divided by 6 equals 27.
10. [tex]90+58 = 148\\180 - 148 = 32\\2(14)+4=32[/tex]
11. 70 and 5x are congruent so, [tex]180-70=110; 110/5 = 35[/tex]

Find the unknown sizes of angles in the following figure (please explain it):
Answer:
x = 56
MKL = 56
KML= 63
MLK = 61
Step-by-step explanation:
We know that the sum of the interior angles of a triangle = 180 degrees.
So, x+ (x+7)+ ( x+5) = 180
3x+ 12= 180
3x= 180-12 = 168
168/3 = x
therefore, x= 56 degrees.
So MKL = 56
KML= 56+ 7 = 63
MLK = 56+5 = 61
