Answer:
Step-by-step explanation:
If AB ⊥ CD, then [tex]m_{AB}[/tex] [tex]m_{CD}[/tex] = - 1
P( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~
y = - 2x + 6 and P(3, 3) , m = - 2
Slope of ⊥ line is [tex]\frac{1}{2}[/tex]
y - 3 = [tex]\frac{1}{2}[/tex] ( x - 3 )
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] or y = 0.5x + 1.5
Which systems have infinite solutions? Check all that apply. y = 0.5x + 2.75 and 2y = x + 2.75 y = 0.5x + 2.75 and y – 0.5x = 2.75 y = 0.5x + 2.75 and 0.5x + y = 2.75 y = 0.5x + 2.75 and y = 0.5(x + 5.5) y = 0.5x + 2.75 and y = –2(–0.25x )+ 2.75
Answer:
Three solutions
Step-by-step explanation:
Infinite solutions means each and every point satisfies both the equations which means there would be a graph that overlaps the original graph.
So compare the equations with the equation
y = 0.5x + 2.75
each and every equation in this form has infinitely many solutions like
y = 0.5x + 2.75 and y - 0.5x = 2.75 these both equations are same. So they have infinitely many solutions as they overlap each other. Furthermore
y = 0.5x + 2.75 and y = 0.5(x + 5.5)
y = 0.5x + 2.75 and y = –2(–0.25x )+ 2.75
all these 4 equations are the same which is y = 0.5x + 2.75 so three systems have infinite solutions we can confirm this by using the desmos online graphing calculator just insert these equations into it and you will see all these equations are the same just like for example
y = 2x and 2y = 4x

Step-by-step explanation:
Sarah needs to find a plumbing company to fix the plumbing in her house. Pat’s Plumbing Company charges a flat rate of $650 to inspect the house plus $25.75 per hour of labor to fix the problem. Her friend Kristin tells her that AAA Plumbing will charge a fee on $675 to inspect the house and an hourly fee of $24.50 for labor. Kristin knows that AAA Plumbing will cost no more than Pat’s Plumbing Company. Which inequality correctly shows the relationship between the total cost of the two plumbing companies?
Answer:
An inequality correctly shows the relationship between the total cost of the two plumbing companies is [tex]675+24.5x \leq 650+25.75x[/tex]
Step-by-step explanation:
Pat’s Plumbing Company
Cost of inspecting house = $650
Cost of labor per hour = $25.75
Cost of labor in x hours = 25.75x
Total cost = 650+25.75x
AAA Plumbing
Cost of inspecting house = $675
Cost of labor per hour = $24.50
Cost of labor in x hours = 24.5x
Total cost = 675+24.5x
We are given that AAA Plumbing will cost no more than Pat’s Plumbing Company
[tex]675+24.5x \leq 650+25.75x[/tex]
Hence An inequality correctly shows the relationship between the total cost of the two plumbing companies is [tex]675+24.5x \leq 650+25.75x[/tex]

3) The length of JM is 9x + 6 units, the length of JK is
5x and the length of KM is 3x +12 units. Find the
Length of JM
J
K
L
M
8
Answer:
[tex] JM = 60 units [/tex]
Step-by-step explanation:
Given:
[tex] JM = 9x + 6 [/tex]
[tex] JK = 5x [/tex]
[tex] KM = 3x + 12 [/tex]
[tex] JK + KM = JM [/tex] (segment addition postulate)
[tex] (5x) + (3x + 12) = (9x + 6) [/tex] (substitution)
Solve for x
[tex] 5x + 3x + 12 = 9x + 6 [/tex]
Collect like terms
[tex] 5x + 3x - 9x = -12 + 6 [/tex]
[tex] -x = -6 [/tex]
Divide both sides by -1
[tex] x = 6 [/tex]
[tex] JM = 9x + 6 [/tex]
Plug in the value of x
[tex] JM = 9(6) + 6 [/tex]
[tex] JM = 54 + 6 [/tex]
[tex] JM = 60 units [/tex]

Sun-Li has 10 blue marbles, 3 red marbles, and 17 white marbles. Write each ratio in ALL three forms.
a.) blue marbles to red marbles =
b.) red marbles to white marbles =
c.) red marbles to total number of marbles =
Answer:
a.) 10:3
b.) 3:17
c.) 3:30
Step-by-step explanation:
There is 10 blue marbles, 3 red marbles, and 17 white marbles.
in total there is 30 marbles because 10+3=13 and 13+17=30.
the ratio of blue marbles to red marbles is 10:3 because there is 10 blue marbles to three red marbles.
the ratio of red marbles to white marbles is 3:17 because there is three red marbles to 17 white marbles.
the ratio of red marbles to total number of marbles is 3:30 because there is three red marbles to 30 marbles in total

Step-by-step explanation:
"Increasing" means the graph goes up to the right. This graph is increasing for values of x greater than 1. (x=1 is a minimum. The graph is decreasing toward the minimum on the left of that value, and increasing from the minimum on the right of that value.)

Total sales is $55,000.
The commission is 3.5%.
Determine the commission .
Answer:
The commission is 1925
Step-by-step explanation:
This is because you are taking 3.5% of $55,000. After doing the percent you are left with $1925 which is the commission.
Hope I helped, Have a great day! :-)
The commission of the total sales of $55000 will be $1925.
What is the percentage?A specific number in every hundred is what is meant by the percentage. The percentage symbol percent is used to denote a fraction with 100 as the denominator.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
The percentage is also called the indicating hundredths. Thus, 3% is two-hundredth, which means 3%=3/100=0.03.
Principle amount = $55000
Commision rate = 3.5%
3.5% of 55000 = (3.5 × 55000)/100
3.5% of 55000 = $1925
Hence the 3.5% commission of the amount of $55000 will be $1925.

Michael received $275 more from relatives than friends. He received $4275 dollars in all, how much money did he receive from relatives and how much money did he receive from friends?
Answer:
4000 thousand from relatives and 275 from friends
Answer:
Michael received $2275 ftom relatives and $2000 from friends
Step-by-step explanation:
Let r represent the amount of money from relatives
Let f represent the amount of money from friends
f+r=4275
f+275=r
Use substitution, f+(f+275)=4275
2f+275=4275
2f=4000
f=2000
Substitute 2000 in for f
2000+275=r
2275=r
