Assuming that the shapes are similar. Find the values of x,y, and z
Answers
Assuming that both figures have the same shape, we can observe that one is bigger than the other, that means that there is a scale factor that must be found before calculating our values.
We can see that we have one side of both figures have the exact value, we will use these to find the scale factor
[tex]\begin{gathered} X\to\text{scale factor} \\ X=\frac{8}{12} \\ X=\frac{2}{3} \end{gathered}[/tex]Now we are going to multiply each of the sides of the big figure by the scale factor and we are going to match it with the corresponding side of the small figure.
To prove that the scale is correct, we try it with the known side:

Kylie wants to ride her bicycle 27.5 miles this week. She has already ridden 9 miles. If she rides for 5 more days, which equation or tape diagram could be used to represent the context if mm represents the average number of miles she would have to ride to meet her goal?
Answers
The equation to represent the context is 9 + 5m = 27.5
How to frame the equation?
Number of miles Kylie wants to ride in a week= 27.5
Number of miles already ridden = 9
Average number of miles to meet her goal = mm
Let average no. of miles in 5 days = 5m
Rewriting as equation,
9 + 5m = 27.5
How to find the average number of miles?
5m = 37.5 -9
5m = 18.5
m = 18.5
[tex]m =\frac{18.5}{5} \\\\m = 3.7 \text{ or } 3\frac{7}{10}[/tex]
Kylie should travel 3.7 miles per day and 18.5 miles in 5 days to meet her goal

The first step to solve this problem is to calculate the missing angle that has its vertex on P. The sum of the internal angles on every triangle is equal to 180 degrees, since we have the other two angles we can calculate the missing one as shown below:

Now we know all the measurements of all the angles and sides of this triangle. When a triangle is rotated its measurements don't change, this means that if a side is equal to 2 before the rotation it should also be equal to 2 after the rotation. With this in mind we can say that:
The length of the side P'Q' is 9 units and the measurement of the angle P' is 97 degrees.

The most appropriate choice for equation of line in slope intercept form will be given by
x -2y = 4 is the required linear function.
What is equation of line in slope intercept form?
Equation of line in slope intercept form is given by y = mx + c
Where, m is the slope of the line and c is the y intercept of the line
The distance from the origin to the point where the line cuts the x axis is called x intercept
The distance from the origin to the point where the line cuts the y axis is called y intercept
Slope of a line is the tangent of the angle which the line makes with the positive direction of x axis
If [tex]\theta[/tex] is the angle which the line makes with the positive direction of x axis, then slope of the line is given by [tex]tan \theta[/tex]
If the line passes through ([tex]x_1, y_1[/tex]) and ([tex]x_2, y_2[/tex])
slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here,
Increase in x value = 4 units
Increase in y value = 2 units
Slope = [tex]\frac{2}{4}[/tex]
Slope = [tex]\frac{1}{2}[/tex]
Let the equation of line be [tex]y = \frac{1}{2}x + c[/tex]
When x = 0, y = -2

SOLUTION:
Case: Augmented Matrix
Given:
In linear algebra, an augmented matrix is a matrix obtained by appending the columns of two given matrices, usually for the purpose of performing the same elementary row operations on each of the given matrices.
Given:
He burns 850 calories when he runs.
he burns 200 calories when he lifts weight
he exercised for a total of 6.5 hours
he burns 2,925 total calories
Method:
First, we make a linear equation:
Assumption: Let the number of hours he runs be r. The number of hours he lifts weights be w.
The equation therefore is:
Hours:
r + w = 6.5
Calories:
850x + 200y = 2925
Final answer:
Augmented Matrix
[tex]\begin{bmatrix}{1} & {1} & {|6.5} \\ {850} & {200} & {|2925} \\ {} & {} & {}\end{bmatrix}[/tex]Solve for r.0.5(r +2.75) = 3
Answers
The given equation is,
[tex]0.5\mleft(r+2.75\mright)=3[/tex]To solve the above equation for r, first divide both sides of the equation by 0.5.
[tex]\begin{gathered} \frac{0.5\mleft(r+2.75\mright)}{0.5}=\frac{3}{0.5} \\ r+2.75=6 \end{gathered}[/tex]Subtract 2.75 from both sides of the above equation.
[tex]\begin{gathered} r+2.75-2.75=6-2.75 \\ r=3.25 \end{gathered}[/tex]Therefore, the value of r is 3.25.

y= 10-4x identity the slope and y-intercept
Answers
Answer:
Step-by-step explanation:
First, graph the expression by making sure it goes through 10 on the y-axis and since it shows -4 that means for every 1 unit to the right the y coordinate moves 4 boxes down. (Your graph should look like a downwards slope)
Now, pick 2 points on your graph, ill pick (0, 10) and (1, 6)
Now, put these in point-slope form and you will get your slope
Point-Slope form
m=y2-y1/x2-x1
m= 10-6/0-1
m= 4/-1
m=-4
Also, you can just see that it's the slope by the graph by using rise over run.
write equation in standard form
y= - 9/11x- 4
Answers
The standard form of the linear equation y = -9/11x - 4 is 9x + 11y = -44.
What is the given equation in standard form?The standard form of a linear equation is expressed as;
Ax + By = C
Where A and B are the coefficient of x and y respectively, C is the constant term.
Given the equation in the question;
y = -9/11x - 4
First, get rid of the fraction by multiplying both sides by //
11( y ) = 11( -9/11x - 4 )
Apply distributive property
11y = -9x - 44
Now, move all terms containing variables to the left and side of the equation.
11y + 9x = -44
Reorder the equation in form of Ax + By = C
9x + 11y = -44
Therefore, the standard form of the equation is 9x + 11y = -44

540 people will be employed as medical assistants in the year 2013.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine the slope of the line :
m = (y₂ - y₁)/(x₂ -x₁ )
m = (560 - 359)/(10-0)
m = 20.1
This represents new assistants per year
So with your y-intercept of 359, your equation becomes
y = 20.1x + 359
Using this equation to estimate the number of people who will be employed as medical assistants in the year 2013.
Let y be the number of medical assistants (in thousands) employed in the country in the year x, where x = 0 represents 2004.
Substitute the value of x = 9 for the year 2013
y = 20.1(9) + 359
y = 180.90 + 359
y = 539.90 ≈ 540
Hence, 540 people will be employed as medical assistants in the year 2013.

F Total cost for two sweatshirts is $27.52.
(you can only choose up to three btw)
Answers
The correct statement are;
⇒ One sweatshirt before tax costs $19.20.
Option A is true.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
Cost of sweatshirts for a store owner = $16
Profit percent = 20%
Sales tax = 7.5%
Now,
Profit price for a sweatshirts = 20% of $16
= 20/100 × 16
= 320 / 100
= $3.20
And, The sales tax price = 7.5% of 16
= 7.5 / 100 × 16
= 120 / 100
= $1.20
So, The cost of one sweatshirt before tax costs = $16 + $3.20
= $19.20
And, Sales tax for one sweatshirt = $1.20
So, Cost of sales tax for two sweatshirt = 2 × 1.20
= $2.40
And, Total cost of a sweatshirt = $16 + $3.20 + $1.20
= $20.4
So, Total cost of two sweatshirt = 2 × $20.4
= $40.8
Thus, The correct statement are;
⇒ One sweatshirt before tax costs $19.20.

One diagonal in a kite divides the angle it traverses. It follows that
4x - 5 = 2x + 35
4x - 2x = 35 + 5
