V=(-6, -5)
Step-by-step explanation:
rotating counter clockwise 90 degrees has a simple formula: (-y, x) simply take your ordered pair and rearrange it to match this formula.
ex. (3, 4) would become (-4, 3)
(-y, x) the negative symbol in front of the y means to switch the sign from either positive or negative to its opposite. since there is no symbol in front of the x you keep that numbers sign the same.

Consider the plot created from the residuals of a line of best fit for a set of data.
Does the residual plot show that the line of best fit is appropriate for the data?
Yes, the points have no pattern.
No, the points are evenly distributed about the x-axis.
No, the points are in a linear pattern.
Yes, the points are in a curved pattern.
Answer:
No, the points are in a linear pattern.
Step-by-step explanation:
Residual plot is a graph that shows the residuals on the vertices. The y-axis has residual values and x-axis has independent variables. The horizontal axis shows the independent variables to determine the best fit for a set. The graph given is in a linear pattern. The random pattern shows that linear model is good fit.

Find the slope intercept form and the point slope the line perpendicular to 4x-7y=2 going through (-6,1)
Answer:
Slope-intercept form: [tex]y=-\frac{7}{4}x-\frac{19}{2}[/tex]
Point-slope-form: [tex]y-1=-\frac{7}{4}(x+6)[/tex]
Step-by-step explanation:
Hi there!
We want to find the equation of the line perpendicular to the line 4x-7y=2 that goes through (-6, 1) in slope-intercept form, as well as the point-slope form
Slope-intercept form is defined as y=mx+b, where m is the slope and b is the y intercept
Point-slope form is defined as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
Meanwhile, perpendicular lines have slopes that are negative and reciprocal. When they are multiplied together, the result is -1
So let's find the slope of the line 4x-7y=2
The equation of the line is in standard form, which is ax+by=c, where a, b, and c are integer coefficients a is non-negative, and a and b aren't 0
So let's find the slope of the line 4x-7y=2
One way to do that is to convert the equation of the line from standard form to slope-intercept form
Our goal is to isolate y onto one side
Subtract 4x from both sides
-7y=-4x+2
Divide both sides by -7
y=[tex]\frac{4}{7}x-\frac{2}{7}[/tex]
So the slope of the line 4x-7y=2 is [tex]\frac{4}{7}[/tex]
Now, we need to find the slope of the line perpendicular to it
Use this formula: [tex]m_1*m_2=-1[/tex]
[tex]m_1[/tex] in this case is [tex]\frac{4}{7}[/tex]
[tex]\frac{4}{7}m_2=-1[/tex]
Multiply both sides by [tex]\frac{7}{4}[/tex]
m=[tex]-\frac{7}{4}[/tex]
Let's see the equation of the perpendicular line so far in slope-intercept form:
y=[tex]\frac{-7}{4}x[/tex]+b
We need to find b now
The equation of the line passes through (-6,1), so we can use it to solve for b.
Substitute -6 as x and 1 as y
[tex]1=-\frac{7}{4}*-6+b[/tex]
Now multiply
1=[tex]\frac{42}{4}+b[/tex]
Subtract 42/4 from both sides to isolate b
-19/2=b
Substitute -19/2 as b into the equation
The equation in slope-intercept form y=[tex]\frac{-7}{4}x-\frac{19}{2}[/tex]
Now, here's the equation in point-slope form
Recall that the slope is [tex]\frac{-7}{4}[/tex] , our point is (-6, 1), and point-slope form is [tex]y-y_1=m(x-x_1)[/tex]
Let's label the value of everything to avoid any confusion
[tex]m=-\frac{7}{4} \\x_1=-6\\y_1=1[/tex]
Now substitute those values into the equation
[tex]y-1=-\frac{7}{4}(x--6)[/tex]
We can simplify the x--6 to x+6
[tex]y-1=-\frac{7}{4}(x+6)[/tex]
Hope this helps!

the Marked price of a computer is rupees 30000 if it is sold after 20 percent discount and then 30% bat is levied on it find the price of the computer including vat.
if u don't know don't answer otherwise I will report u
Answer:
31200
Step-by-step explanation:
First, the starting price is 30000. We then must find the value after a 20% discount is applied. To do this, we can first convert 20% into a decimal value. That can be obtained by multiplying the percent by 1/100, so 20% * 1/100 = 0.2 . Therefore, the discount is 30000 * 0.2 = 6000 . Discounts work by subtracting the discount from the market price to get the final value, so we have
30000 - 6000 = 24000 as the value before tax.
Then, we can include the VAT, which is 30% of our new price. 30% as a decimal is 30 * 1/100 = 0.3, so we can find the tax of our product as 0.3 * 24000 = 7200. Taxes work by adding the taxed value on top of the price, so we can add 7200 to the value before tax to get 31200 as the final price including VAT

Answer:
a = 20; b = 10sqrt(3)
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
b = 10 * sqrt(3)
b = 10sqrt(3)
a = 2(10)
a = 20
Answer: a = 20; b = 10sqrt(3)
Answer:
a=20,[tex]b=10\sqrt{3}[/tex]
Step-by-step explanation:
SOH-CAH-TOA
Tan = O/A
Tan(60)= b/10
[tex]b=10\sqrt{3}[/tex]
Cos = A/H
cos(60) = 10/a

The x and y intercepts of a line are when [tex]y=0[/tex] and [tex]x=0[/tex] respectively.
c and d are the x and y intercepts because they represent C/A and B/A in the standard linear equationThe x and the y intercepts are related to c and d because they represent the values of the equation when y and x equals 0 respectively.The given equation is:
[tex]\frac xc + \frac yd = 1[/tex]
(1) Why c and d are the intercepts
We have:
[tex]\frac xc + \frac yd = 1[/tex]
Multiply through by cd
[tex]cd \times \frac xc + cd \times \frac yd = cd \times1[/tex]
[tex]dx + cy = cd[/tex]
A linear equation is represented as:
[tex]Ax + By = C[/tex]
Where:
[tex]\frac CA \to[/tex] x intercept
[tex]\frac BA \to[/tex] y intercept
So, by comparing [tex]Ax + By = C[/tex] to [tex]dx + cy = cd[/tex]
[tex]\frac CA \to d \to[/tex] The x-intercept
[tex]\frac CB \to c \to[/tex] The y-intercept
(b) How the intercepts are related to c and d?
In (a) above, we have:
[tex]\frac CA \to d \to[/tex] The x-intercept
[tex]\frac CB \to c \to[/tex] The y-intercept
When [tex]x = 0[/tex]
We have:
[tex]dx + cy = cd[/tex]
[tex]d \times 0 + cy = cd[/tex]
[tex]cy = cd[/tex]
Divide by c
[tex]y = d[/tex] ---- the y-intercept
When [tex]y = 0[/tex]
We have:
[tex]dx + cy = cd[/tex]
[tex]dx + c \times 0 = cd[/tex]
[tex]dx = cd[/tex]

or, x=11
you went to the restaurant and you paid $28 for food. you decide to tip the waiter 15% and pay tax 10%. what was the final bill after tip and tax?
==================================================
Work Shown:
15% of 28 = 0.15*28 = 4.20 is paid as a tip
10% of 28 = 0.10*28 = 2.80 is paid as tax
28+4.20+2.80 = 35 dollars is the final bill after both tip and tax are included.
-2(8 - 1)= complete the following statement
We simplify the expression by subtracting 1 from 8, resulting in 7. We then multiply 7 by -2 to obtain the final answer of -14.
To simplify the given expression, -2(8 - 1), we can start by evaluating the expression inside the parentheses,
8 - 1 = 7
Now, we substitute this value back into the original expression:
-2(7)
Multiplying -2 by 7, we get:
-2 * 7 = -14
Therefore, -2(8 - 1) simplifies to -14.
In this case, we simplified the expression inside the parentheses first and then applied the multiplication operation. It's important to remember that when there is a negative sign in front of parentheses, it distributes to each term inside the parentheses. So, -2 multiplied by 8 gives -16, and -2 multiplied by -1 gives +2. The sum of -16 and +2 is -14.
In summary, when we evaluate the expression -2(8 - 1), the result is -14. This means that if we follow the order of operations (parentheses first, then multiplication), we simplify the expression by subtracting 1 from 8, resulting in 7. We then multiply 7 by -2 to obtain the final answer of -14.
