Problem 9) x = 1Problem 10) x = 3Problem 11) x = 12Problem 12) x = 12==============================================
Explanation:
For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.
------------------
In problem 9, we have the following steps
(79x-1) + (102) = 180
79x + 101 = 180
79x = 180-101
79x = 79
x = 79/79
x = 1
------------------
Problem 10 is the same idea
(85) + (30x+5) = 180
30x+90 = 180
30x = 180-90
30x = 90
x = 90/30
x = 3
------------------
Problem 11
(55)+(9x+17) = 180
9x+72 = 180
9x = 180-72
9x = 108
x = 108/9
x = 12
------------------
Problem 12
(3x+12)+(132) = 180
3x+144 = 180
3x = 180-144
3x = 36
x = 36/3
x = 12
Answer:
9. X = 1
10. X = 3
11. X = 12
12. X = 12
Step-by-step explanation:
9.
1) 79x - 1 + 102 = 180
2) 79x + 101 = 180
3) Subtract 101 from both sides
4) 79x = 79
5) x = 1
10.
1) 85 + 30x + 5 = 180
2) 30x + 90 = 180
3) Subtract 90 from both sides
4) 30x = 90
5) x = 3
11.
1) 55 + 9x + 17 = 180
2) 9x + 72 = 180
3) Subtract 72 from both sides
3) 9x = 108
4) X = 12
12.
1) 3x + 12 + 132 = 180
2) 3x + 144 = 180
3) Subtract 144 from both sides
4) 3x = 36
5) x = 12
All answers have been checked by plugging the X back into the equation.

Which is the graph of the linear inequality x – 2y > –6?
Answers
Answer:
uhhh d????
Step-by-step explanation:
Graph D represents the linear inequality x – 2y > –6.
The given inequality is x – 2y > –6.
We rearrange the inequality as y < (1/2)x + 3
Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).
To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).
The slope of the graph is 1/2.
However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.
Hence, graph D represents the linear inequality x – 2y > –6.

Answers
Answer:
point slope form is below. since you have the slope already, all you have to do is plug in the point for x1 and y1 and then the slope for m
y - y1 = m(x -x1)
y - 2 = -4 (x - 2) (this is the equation)

explain how it is possible that all proportional relationships are linear functions but not all linear functions are proportional relationships.
Answers
Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).

Kiran paid $54.00 for 3 tickets to go to a corn maze. At the same rate, what is the cost of 5 tickets to the maze? *
Answers
Answer:90
Step-by-step explanation:
Answer: $90
Step-by-step explanation:
You can set up a proportion.
$54 = 3 tickets
x = 5 tickets
To find x, multiply 54 and 5.
54 × 5 = 270
Then divide 270 by 3.
270 ÷ 3 = $90
Since we figured out x = $90, this means that it costs $90 for 5 tickets.

Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan rides at a constant speed of 8 miles per hour, and Nathan rides a constant speed of 10 miles per hour. How long does it take until Reagan and Nathan meet?
Answers
Answer:
They meet in 2.22 hours.
Step-by-step explanation:
We can find the time at which Reagan and Nathan meet by equaling the time as follows:
[tex] v_{R} = \frac{x_{R}}{t} [/tex]
[tex] x_{R} = v_{R}t [/tex] (1)
[tex] v_{N} = \frac{x_{N}}{t} [/tex]
[tex] x_{N} = v_{N}t [/tex] (2)
Where R is for Reagan and N for Nathan.
Knowing that:
[tex] x_{R} + x_{N} = 40 mi [/tex]
By adding equations (1) and (2) we have:
[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]
[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]
Therefore, they meet in 2.22 hours.

2) The given parameters are;
The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)
Therefore, we have;
The length of segment AB = 1
The length of segment BC = 2
The length of segment AD = 2
The length of segment DE = 4
Therefore, we have;
∠ABC = ∠ADE = 90°
∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°
Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate
