Answer:
A
Step-by-step explanation:
The answer is the first one. We've used that in previous questions.
B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.
C is wrong. the third angle's x term has to be plus.
D has the same problem.

Step-by-step explanation:
The diagram below shows a map of the routes taken by Georgia Air-Taxi airline. On this diagram lengths and directions are irrelevant, all that matters is the connections between airports. Choose the adjacency matrix, name it A, that matches the scenario.
Answer: B
Step-by-step explanation: Adjacency Matrix is a square matrix representing a simple graph with 0 or 1 according to the condition given.
In this diagram, 0 corresponds to no connection between airports and 1 corresponds to connections between airports.
In other words, analysing the image, we see that:
1) Albany just have connection with Atlanta, so in the position of line Albany with column At, it must be a 1. The other columns, there are 0.
The Line for Albany in the matrix will be: [0 1 0 0 0 0]
2) Atlanta has connections with Albany, Dalton, Macon and Augusta. So corresponding position (line and column) must be 1. The only two airports Atlanta doesn't have connection with its own and Waycross, so at the corresponding column and line, it is written 0.
The line for Atlanta in the matrix is [1 0 1 1 1 0]
3) Augusta: connections with Atlanta, Macon, Waycross. At those positions, it will be written 1. At positions related to itself, Albany and Dalton is 0.
The line in the matrix will be [0 1 0 0 1 1]
4) Dalton: connection with Atlanta only. That position will be 1 while the others will be 0.
The line is [0 1 0 0 0 0]
5) Macon: connections with Atlanta, Augusta and Waycon: those positions will have 1 and the other 0.
The line is [0 1 1 0 0 1]
6) Waycross: connections with Macon and Augusta. Those positions will be 1 and the others 0.
The line is [0 0 1 0 1 0]
In conclusion, the adjacency matrix matching the scenario is
[tex]A=\left[\begin{array}{cccccc}0&1&0&0&0&0\\1&0&1&1&1&0\\0&1&0&0&1&1\\0&1&0&0&0&0\\0&1&1&0&0&1\\0&0&1&0&1&0\end{array}\right][/tex]

What are the slope and y-intercept of the line?
A. The slope is approximately 3 and the y-intercept is 2.
B. The slope is approximately 1.33 and the y-intercept is 2.
C. The slope is approximately 2 and the y-intercept is 3.
D.The slope is approximately 2 and the y-intercept is 1.33.
Answer:
B.The slope is approximately 1.33 and the y-intercept is 2.
Step-by-step explanation:
On the graph we are going based off where the line starts and in this case it starts on the y line and that shows our y-intercept is 2. The line also doesn't have a rate of change that is directly being put onto an intersecting point like (2,2) which would make it a decimal 1.33.
Answer:
B. The slope is approximately 1.33 and the y-intercept is 2.
Step-by-step explanation:
We can eliminate answers C and D because the y-intercept is 2.
The slop is approximately 1.33 because if we go over 1 unit, we must go up approximately 1.33 units to follow the line.

Ethan works at an electronics store as a salesperson. Ethan earns a 5% commission on the total dollar amount of all phone sales he makes, and earns a 4% commission on all computer sales. Ethan had twice as much in computer sales as he had in phone sales and earned a total of $117 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Ethan made and the dollar amount of computer sales he made. Define the variables that you use to write the system.
Answer:
0.05x+0.04y=117
y=2x
where:
x is the amount of all phone sales
y is the amount of all computer sales
Step-by-step explanation:
From the information given, the first equation would indicate that the comission of all phone sales plus the comission from all computer sales would be equal to 117, which is:
0.05x+0.04y=117, where:
x is the amount of all phone sales
y is the amount of all computer sales
Also, the statement indicates that Ethan had twice as much in computer sales as he had in phone sales, which would be:
y=2x
Now, you can replace y=2x in the first equation and solve for x:
0.05x+0.04(2x)=117
0.05x+0.08x=117
0.13x=117
x=117/0.13
x=900
Finally, you can replace the value of x in y=2x to find the value of y:
y=2(900)
y=1800

Answer:
The answer is c.29
Step-by-step explanation:
I used Google xD
Answer:
Largest number = 29
Step-by-step explanation:
Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)
x +1 + x + 2 + x + 3 = 84 {Combine like terms}
x + x +x + 1 + 2 + 3 = 84
3x + 6 = 84
3x = 84 - 6
3x = 78
x = 78/3
x = 26
Largest number = x + 3 = 26 + 3
=29

If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________
i think the answer will be 6.
Answer:
x = -7
HI = -18
ID = -36
Step-by-step explanation:
I'm guessing that H is the midpoint, so that would mean DH = HI.
So plug in.
4x + 10 = 2x - 4 (subtract 2x on both sides)
2x + 10 = -4 (subtract 10 on both sides)
2x = -14 (divide by 2 on both sides)
x = -7
PLUG IN TO GET ID because DH + HI = ID
4(-7) + 10 + 2(-7) - 4 (simplify)
-28 + 10 -14 - 4 (collect like terms)
-46 + 10 = -36
ID = -36
HI = 2(-7) -4 (simplify)
HI = -14 -4
HI = -18
Hope this helps!!
Use the order of operations to evaluate: −7.6 − 2[9 + (−6.8)] First, simplify the parentheses: [9 + (−6.8)] = 2.2. Now the expression is: −7.6 − 2(2.2). Since there are no exponents in this problem, the next step is ✔ (- 2)2.2 . Simplify the previous step and you get ✔ -7.6 – 4.4 . The final answer is
Answer:
-12.0
Step-by-step explanation:
From the above question, we are given:
−7.6 − 2[9 + (−6.8)]
We apple the PEDMAS rule
P = Parentheses, Hence:
Step 1
The first step is to simplify the parentheses
[9 + (−6.8)] = 2.2.
Step 2
We now have:
−7.6 − 2(2.2).
Step 3
We simplify Parentheses again
(- 2)2.2 = -4.4
Step 4
We simplify
-7.6 - 4.4
= -12.0
The final answer is 12.0
have a nice day, good luck
