The line segments connecting the points (x1, y1), (x2, y1), and (x2, y2) form a triangle. Is the triangle a right triangle?
Answer:
Indeed, the given triangle is a right triangle.
Step-by-step explanation:
A triangle is formed by the following three points: [tex]A(x,y) = (x_{1}, y_{1})[/tex], [tex]B(x,y) = (x_{2}, y_{1})[/tex] and [tex]C(x,y) = (x_{2}, y_{2})[/tex]. Then, we construct the following vectors:
[tex]\overrightarrow {BA} = (x_{2}-x_{1}, y_{1}-y_{1})[/tex]
[tex]\overrightarrow{BA} = (x_{2}-x_{1}, 0)[/tex] (1)
[tex]\overrightarrow{BC} = (x_{2}-x_{2}, y_{2} - y_{1})[/tex]
[tex]\overrightarrow{BC} = (0, y_{2}-y_{1})[/tex] (2)
If triangle ABC is a right triangle, then [tex]\overrightarrow{BA}\,\bullet\,\overrightarrow{BC} = 0[/tex]. By (1) and (2) we have this expression:
[tex](x_{2} - x_{1})\cdot (0) + (0)\cdot (y_{2} - y_{1}) = 0[/tex]
Therefore, the given triangle is a right triangle.

Jazmine has 4 and 2/3 fluid ounces of coffee creamer. She uses 1/6 fluid ounce of creamer in each cup of coffee. How many cups of coffee can jazmine make with her creamer?
Simplify your answer.
Answer:
28 cups of coffee
Step-by-step explanation:
We can start by converting so that the two numbers have the same denominator. 4 2/3 as an improper fraction is 14/3. Then, you would multiply the top and bottom by 2 which is 6. So, your new fraction is 28/6, which is equal to 4 2/3. Divide by 28/6 by 1/6 to get 28.

Answer:
1st Option;
j = 4.5
k = 2
Step-by-step explanation:
Let's solve for "j" first:
=> We know that by the definition of midpoint segment theorem we can say;
3j = 5j - 9
0 = 5j - 3j - 9
0 = 2j - 9
0 + 9 = 2j
9 = 2j
9/2 = j
4.5 = j
=> Now that we have j-value we use the same method to solve for k-value;
6k = k + 10
6k - k = 10
5k = 10
k = 10/5
k = 2
Therefore;
j = 4.5
k = 2
So the first option would be correct!
Hope this helps!

Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.

Erica rented a scooter for $12 per hour plus a $25 gas fee. She spent a total of $73 to rent the scooter. Which equation represents the number of hours, h, Erica rented the scooter?
A
25h+12=73
B
12h+25=73
C
12h−25=73
D
25h−12=73
The equation that represents the number of hours, h, Erica rented the scooter is 25h + 12 = 73.
Consider variable h represents the number of hours Erica rented the scooter.
The term 25h represents the cost of the gas fee, which is $25 multiplied by the number of hours.
The term 12 represents the cost per hour of renting the scooter.
The equation states that the sum of the gas fee and the rental fee per hour equals the total cost of $73.
Therefore, the correct equation is:
25h + 12 = 73, which represents the number of hours Erica rented the scooter.

If y varies inversely as x
and x = 4 when y = 15, find y when x=6
Answer:
y = 10
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition x = 4 when y = 15 , then
15 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
60 = k
y = [tex]\frac{60}{x}[/tex] ← equation of variation
When x = 6 , then
y = [tex]\frac{60}{6}[/tex] = 10

What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
