Two parallel lines are crossed by a traversal. What is the value of h?
h=60
h=80
h=100
h=120
Answers
Answer:
h=60
Step-by-step explanation:
The angle that is 120 degrees and the angle that is h degrees are called same side interior angles
Same side interior angles are supplementary, meaning that they add to 180 degrees
To find h we can use Measures addition postulate to find the unknown value h
h+120=180
h=60

Answers
Answer:
Hope I'm not too late for this...
(look below)
Step-by-step explanation:
For the first part:
1. b = -1, m = 2
The y-intercept (b) is the value of y when x = 0. In this case, we can see that when x = 0, y = -1 so the y-intercept is -1.
The slope was found using the equation slope (m) = (y2-y1) / (x2-x1) and two points. (Note, you can choose any two points, I just chose the first two.)
(5,9) (-2,-5)
slope = (y2-y1) / (x2-x1)
slope = (-5-9) / (-2-5)
slope = -14/-7
slope = 2
I used the same steps as shown above:
2. b = 2, m = -3
For the second part:
1. y = 2x - 1
2.y = -3x + 2
I basically plugged in the values for m and b into the equation, y = mx + b.
Graphs:
The way to graph a line is to plot at least two points and draw a line through them. You can graph it using either the equation or the table. I used the table since it is much easier to find the points that I need.
Below I have included references to what the graph should look like if you need to check your work.
The one in blue is for the equation y = 2x - 1. This should help you get a visual of what the correct graph looks like.
The one in green is for the equation y = -3x + 2.
I hope this helped!

Mr. Ash owns a tree, which is 42 feet tall. He estimates that this tree is 75% as tall now as it will be when fully grown. How tall will the tree be when it is fully grown?
Answers
Answer:
73.5 feet
Step-by-step explanation:
The length of a tree =42 feet
Mr. Ash estimates that this tree is 75% as tall now as it will be when fully grown.
We need to find the length of the tree when it is fully grown. It means we need to find the 75% of 42 and adding 42 to it as follows :
[tex]T=75\%\times 42+42\\\\=\dfrac{75}{100}\times 42+42\\\\=73.5\ ft[/tex]
So, the tree will be 73.5 feet tall when it is fully grown.

Two containers P and Q are filled with different amounts of water. Each container has a small hole. The graph shows the amount of water, V milliliters, left in each container after x minutes.
Explain what the y-intercept means in this scenario.
Answers
Answer:
Step-by-step explanation:
Equation of the line for container O and container P will be in the form of,
y = mx + b
Here m = slope of the line = Change in amount of water per minute
b = y-intercept
From the graph attached,
y-intercept 'b' represents the initial amount of water in the container.
For container O, initial amount of water in the container is 1000 mL.
Similarly, initial amount in the container is 900 mL.
Which equation represents a line that is perpendicular to y=x?
A.
y=2x
B.
y=−x+6
C.
y=−2x
D.
y=x+1
Answers
Answer:
B
Step-by-step explanation:
The general equation of a straight line can be represented as;
y = mx + b
where m is slope
If two lines are perpendicular, the product of their slopes will be -1
So since the slope of the first line is 1, then the slope of the second line will be -1
Out of all the options, only have its slope as -1 and this y = -x + 6 and this is our answer
pls help Solve for m. -7+4m+10=15-2m
Answers
Answer:
m=2
Step-by-step explanation:
Answer:
[tex]m=2[/tex]
Step-by-step explanation:
[tex]-7+4m+10=15-2m[/tex]
Isolate the variable m. Combine like terms (-7+10):
[tex]3+4m=15-2m[/tex]
Subtract 3 from both sides (inverse operations):
[tex]3-3+4m=15-3-2m\\\\4m=12-2m[/tex]
Add 2m to both sides (inverse operations):
[tex]4m+2m=12-2m+2m\\\\6m=12[/tex]
Divide both sides by 6 to isolate m (inverse operations):
[tex]\frac{6m}{6} =\frac{12}{6} \\\\m=2[/tex]
Since this cannot be further simplified, m is equal to 2.
