The two 3s can reduce the result further. sqrt (2 * 3 * 3)
square root 18 = 3*sqrt(2)
There are two sides with this length. Their total is 3sqrt(2) + 3sqrt(2) = 6√2

Find the inequality represented by the graph.
Answer:
y > 4x - 2Step-by-step explanation:
First, let's find the equation of the line.
Use points (0, -2) and (1, 2) on the graph.
The y-intercept is (0, -2), find the slope:
m = (y2 - y1)/(x2 - x1) = (2 - (-2))/(1 - 0) = 4/1 = 4The line is:
y = 4x - 2Now, we see the line is dotted and the space to the left side is shaded.
Dotted line means the inequality doesn't include the points on the line, therefore the sign would be > or <.
Since the left side of the line includes greater values of the function, it should have > sign.
So the inequality is:
y > 4x - 2Help me pleaseeee I would be happy

Which of the following transformations always preserve the orientation of a figure?
1- Translations
2- Rotations
3- Reflections
4- None of them
Answer:
Translation
Step-by-step explanation:
Translation is when something moves or slide. Orientation refers to the way it is facing or turned.
The required given statement is Reflections is transformations always preserve the orientation of a figure.
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
The given statement is which transformations always preserve the orientation of a figure.
According to given question we have
Reflection is a type of transformation in which the given image is flipped across a line of reflection to create the transformed image. In this transformation, dimensions of the figure is always preserved.
In a translation, the preimage and image have the same orientation. In a rotation, the orientation of the preimage is changed. Both are rigid transformations.
Therefore, the required given statement is Reflections is transformations always preserve the orientation of a figure.

Answer:
The the linear equation in point-slope form is
[tex]y-3 = -2 (x-4)[/tex]
Step-by-step explanation:
Given
slope = m = -2point (4, 3)We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here:
m is the slope(x₁, y₁) is the pointsubstituting the values m = -2 and the point (4, 3) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-3 = -2 (x-4)[/tex]
Thus, the the linear equation in point-slope form is
[tex]y-3 = -2 (x-4)[/tex]
Note: This equation could be further simplified to write it in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so writing the equation in the slope-intercept form
[tex]y-3 = -2 (x-4)[/tex]
[tex]y-3 = -2x+8[/tex]
[tex]y=-2x+8+3[/tex]
[tex]y=-2x+11[/tex]
Thus, the equation is the slope-intercept form is
[tex]y=-2x+11[/tex]What is cot(< a)?

cot (∠A) = adjacent / opposite
= 3/4
Thus, the value of cot (∠A) = 3/4

Write the slope -intercept form of the given line.include your work in your answer.Type your answer in the box provided or
The equations of four lines are given. Identify which lines are parallel.
Line 1:
y=-7x + 6
Line 2:
x +1/5y=-6
Line 3:
y=-5x -8
Line 4:
y+7=-1/7(x+4)
Answer:
Line 2 and 3 are parallel
Step-by-step explanation:
Recall that the general equation of a line in slope-intercept form is given by:
y = mx + b
where m is the gradient (slope).
two different equations that have the same value of m is said to have the same gradient and hence are parallel.
We simply have to rearrange each given equation so that it takes the form
y = mx + b and then compare all 4 to see which values of m are the same.
Line 1 : y = -7x + 6
Line 2: x +(1/5)y=-6 ===> rearrange to get y = -5x - 30
Line 3: y= -5x -8
Line 4: y+7=(-1/7)(x+4) ===> rearrange to get y = (-1/7)x - (53/7)
comparing the above, it is clear that line 2 and line 3 have m- values of m = -5, hence these lines are parallel.

Samir's SE tax for 2020 is $7,771 [$55,000 x 0.9235 x 0.153 = $7,771]. Samir may reduce his estimated tax payments by how much?
Answer:
Step-by-step explanation:
Since he is his own boss, he is basically a self employed taxpayer and should be to deduct the employer portion of self employment taxes that he/she pays during the year.
In a case like this, the total self employment taxes are $7,771 x 50% = $7,771 * 0.5 = $3,885.50. This money also now, is corresponding to employer taxes (the other 50% are not deductible since they correspond to employee taxes).
Self employment taxes composes but not limited to Medicare and Social Security taxes (FICA taxes basically).
(X-6)^2 multiply and expand
Answer:
x² - 12x + 36
Step-by-step explanation:
Given
(x - 6)² = (x - 6)(x - 6)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 6) - 6(x - 6) ← distribute both parenthesis
= x² - 6x - 6x + 36 ← collect like terms
= x² - 12x + 36

Answer:
D. 5
Step-by-step explanation:
From the information given:
The derivatives of functions and functions have a different average rate. The average rate expanded over an interval of two distinct point (a f(a)) and (b f(b)) is represented by the equation:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
where; the two points are:
(-1 , f( -1) ) & ( 1, f(1) )
For f(1); we have:
f(1) = 1 +3(1)³ - 5(1)² + 2(1) - 2
f(1) = 1 + 3 - 5 + 2 -2
f(1) = - 1
For f( -1); we have:
(-1)⁴ + 3(-1)³ - 5(-1)²+2(-1)-2
= 1 - 3 - 5 -2 - 2
= -11
∴
[tex]=\dfrac{-1-(-11)}{1 - (-1)}[/tex]
[tex]=\dfrac{-1+11}{1 +1}[/tex]
[tex]=\dfrac{10}{2}[/tex]

Easton is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Easton scored a total of 21 points and made twice as many two point shots as three point shots. Write a system of equations that could be used to determine the number of two point shots Easton made and the number of three point shots he made. Define the variables that you use to write the system
Answer:
2+3y=21
x=2y
Step-by-step explanation:
Each two point shot scores 2 points, so xx two point shots would score 2x points. Each three point shot scores 3 points, so y three point shots would score 3y points. Therefore, the total number of points scored 2x+3yy equals 21
Since Easton scored twice as many two point shots as three point shots, he made more two point shots, so if we multiply 2 by the number of three point shots made, we will get the number of two point shots made, meaning x equals 2y
