Put the following equation of a line into slope-intercept form, simplifying all
fractions.
2x - 3y = 18
Answer:
y = (2/3)x - 6Step-by-step explanation:
Slope-intercept form is:
y = mx + bConvert the given equation as following:
2x - 3y = 18 Isolate the term with y3y = 2x - 18 Divide all terms by 3y = (2/3)x - 6Solve the inequality and draw the solution |r|-3>2
We want to solve the following inequality
[tex]|r|\text{ -3 >2}[/tex]To solve this inequality, we first add 3 on both sides, so we get
[tex]|r|>2+3=5[/tex]So we have the inequality
[tex]|r|>5[/tex]Recall that the absolute value represents the distance from a number to 0. So this means that the number r is greater than 5 or it is less than -5. So we have the following two inequalities
[tex]r>5[/tex][tex]r<\text{ -5}[/tex]This could be drawn on the number line as follows. Greater than (>) means that the number 5 is on the left, and the less than (<) means that the number -5 is on the right side. So we get the following
Write the equation of the circle given the following information
Given;
There are given that points are:
[tex](1,13)\text{ and \lparen-3,-9\rparen}[/tex]Explanation:
From the standard form of the circle:
[tex](x-a)^2+(y-b)^2=r^2[/tex]Where
a and b represent the center.
Now,
To establish the equation, we require to know it is center and radius.
Since we are given the endpoints of the diameter
Then,
The center will be at the midpoint and the radius will be the distance from the center to either of the two given points.
Then,
From the formula of midpoint to calculate the midpoint:
[tex](x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]Then,
From the given two points:
[tex]\begin{gathered} (x,y)=(\frac{1-3}{2},\frac{13-9}{2}) \\ (x,y)=(-\frac{2}{2},\frac{4}{2}) \\ (x,y)=(-1,2) \end{gathered}[/tex]The midpoint is ( -1, 2).
Now,
We need to find the value of the radius.
So,
To calculate the radius, we need to use the distance formula:
Then,
From the formula of distance, here we will use the points: (-1, 2) and (1, 13)
[tex]\begin{gathered} r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ r=\sqrt{\left(1+1\right)^2+\left(13-2\right)^2} \\ r=\sqrt{4+121} \\ r=\sqrt{125} \end{gathered}[/tex]Now,
We have the value of radius and the point of center.
Then,
Put the value of radius and point of the center into the standard form of the circle:
So,
From the standard form of the circle:
[tex]\begin{gathered} (x-a)^{2}+(y-b)^{2}=r^{2} \\ (x-\left(-1\right))^2+(y-2)^2=\lparen\sqrt{125}^)^2 \\ (x+1)^2+(y-2)^2=125 \end{gathered}[/tex]Final answer:
Hence, the equation of the circle is shown below;
[tex](x+1)^{2}+(y-2)^{2}=125[/tex]What is the value of x?

1. Find the LCM of the two denominators: x-1 and x -3
This is (x-1)(x-3)
2. Multiply each numerator by the same amount needed to multiply itscorresponding denominator to turn it into the LCM (x−1)(x−3)
[tex]\mathrm{For}\:\dfrac{x-3}{x-1}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:x-3[/tex]
[tex]\dfrac{x-3}{x-1} = \dfrac{\left(x-3\right)\left(x-3\right)}{\left(x-1\right)\left(x-3\right)} = \dfrac{\left(x-3\right)^2}{\left(x-1\right)\left(x-3\right)}[/tex]
[tex]\mathrm{For}\:\dfrac{6}{x-3}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:x-1[/tex]
[tex]\dfrac{6}{x-3} = \dfrac{6\left(x-1\right)}{\left(x-3\right)\left(x-1\right)} = \dfrac{6\left(x-1\right)}{\left(x-1\right)\left(x-3\right)}[/tex]
[tex]2. \mathrm{Simplify\:}\left(x-3\right)^2+6\left(x-1\right)[/tex]
[tex]\left(x-3\right)^2 = x^2 - 6x + 9\\\\\\3. \; \text{Expand }6\left(x-1\right)\;6\left(x-1\right) = 6x-6\\\\[/tex]
4. Since the denominators are the same in both terms, we can add the numerators and use the common denominator as the denominator for the result
Adding numerators derived from steps 2 and 3 above we getAnswer:
While adding two Fractions first we find the LCM of Denominators,
The LCM of x-1 and x-3 is (x-1)(x-3)
now, we perform the calculation as ,

The total cost of the chocolate cookies is $300
The markup cost on cookies is $135
The total selling price of cookies is $435
The percentage of defective cookies is 15%.
The number of sellable cookies after removing the defective cookie is 170
The price of each cookie is $2.56
What is the total cost?The total cost of the chocolate cookies is the product of the cost per cookie and the number of cookies produced.
Total cost = cost per cookie x total cookies produced
$1.50 x 200 = $300
The markup cost on cookies can be determined by multiplying the percentage markup by the total cost of cookies
Markup = percentage markup x total cost of cookies
45% x $300
0.45 x $300 = $135
The total selling price of cookies is the sum of the markup on cost and the total cost of producing the cookies
Total selling price = $135 + $300 = $435
Number of sellable cookies after removing the defective cookies = (1 - percentage of defective cookies) x number of cookies produced
200 x (1 - 0.15)
200 x 0.85 = 170
Price of each cookie = total cost after markup / total number of sellable cookies
435 / 170 = $2.56

Which set of ordered pairs (x,y) could represent a linear function?A. {(-7,3), (-2,1), (3,-1), (8,-3)}B. {(-2,8), (-1,4), (1,0), (3,-4)}C. {(-3,-6), (0,-5), (3,-3) (6,-2)}D. {(0,-8), (3,-5), (5,-2), (8,1)}
Answer:
A. {(-7,3), (-2,1), (3,-1), (8,-3)}
Explanation:
A linear function has a constant slope.
To determine the set of ordered pairs (x,y) that could represent a linear function, we find the slope for two pairs of points.
[tex]\text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}[/tex]Option A
Using points (-7,3) and (-2,1).
[tex]\text{Slope}=\frac{3-1}{-7-(-2)}=\frac{2}{-7+2}=-\frac{2}{5}[/tex]Using points (-7,3) and (3,-1).
[tex]\text{Slope}=\frac{3-(-1)}{-7-3}=\frac{4}{-10}=-\frac{2}{5}[/tex]We see that the slopes are the same.
Therefore, the set of ordered pairs in Option A represent a linear function.
4. During a long weekend, Devon paid a total of x dollars for a rental car so he could visit his family. He rented the care for 4 days at a rate of $36 per day. There was an additional charge of $0.20 per mile after the first 200 miles.
a. Write an expression to represent the amount Devon paid for additional mileage.
b. Write an expression to represent the number of miles over 200 miles that Devon drove.
c. How many miles overall did Devon drive overall if he paid $174 for the car rental? Show work.
Answer:
A)
c = 0.20m + 144
Where c is total cost and m is miles driven.
B)
c = (200 + 0.20m) + 144
C)
174 = 0.20m + 36x4
174 = 0.20m + 144
30 = 0.20m
30/0.20 = m
m = 150+200
m = 350miles

A is the amount after t years.
P is the principal.
r is the annual interest rate.
Therefore the equation is:

The most appropriate choice for Similar and congruent triangles will be given by
Third Option dilation is correct.
What are Similar and congruent triangles?
Two triangles are similar if their angles are equal but their sides are proportional
The different axioms of similarity are SAS, SSS, AA
Two triangles are congruent if their sides and angles are both equal
The different axioms of congruency are ASA, SAS, AAS, RHS, SSS
Here, A stands for angle, S stands for side R stands for right angle, H stands for hypotenuse.
Here,
Two Similar triangle means corrosponding sides are proportional and two congruent triangle means corrosponding sides and angles and angles are same
The triangle after rotation and reflection do not change any length of side or angle. So the triangles will be same after reflection or rotation. So congruency will not be disturbed here.
Now, in case of dilation, length of each side will change but in same proportion.
So dilation can make two similar triangles but not congruent triangles
So third option is correct.

chords AB and CD intersect as shown nelow find the length of CD
We are asked to determine the length of CD, to do that we will use the following relationship:
[tex]\begin{gathered} CD=21+x+1 \\ CD=22+x \end{gathered}[/tex]Therefore, we need to determine the value of "x". To do that we will use the intersecting chords theorem, that is:
[tex](21)(x+1)=(9)(3x-9)[/tex]Now we solve for "x" first by applying the distributive law:
[tex]21x+21=27x-81[/tex]Now we will subtract 21 to both sides:
[tex]\begin{gathered} 21x=27x-81-21 \\ 21x=27x-102 \end{gathered}[/tex]Now we will subtract 27x to both sides:
[tex]\begin{gathered} 21x-27x=-102 \\ -6x=-102 \end{gathered}[/tex]Dividing both sides by -6:
[tex]x=-\frac{102}{-6}=17[/tex]Now we replace the value of "x" in the expression for segment CD:
[tex]\begin{gathered} CD=22+17 \\ CD=39 \end{gathered}[/tex]Therefore, the length of CD is 39.
