Answer:
The first answer choice= y = 50x
Step-by-step explanation:
Because you find a point on the graph that is exactly on a point and divide the y by the x and you get the constant. THen in the answer choices only y = 50x is a larger number than 25 which in this case is the constant!

1. What is the space inside an object called? What type of objects have volume?
2. Compare the slopes of parallel lines and perpendicular lines.
3. Explain the difference between a secant and a tangent.
Answer:
1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.
2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees
3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)
Step-by-step explanation:

Answer:
77°
Step-by-step explanation:
60°+128°+95°=283°
The sum of all angles = 360°
360°-286°=77°
Edit : Typo
Answer:
x = 77 degrees
Step-by-step explanation:
All angles of a trapezoid will add up to equal 360 degrees.
In other words: 60 + 128 + 95 + x = trapezoid
60 + 128 + 95 = 283 degrees.
360 - 283 = 77
x = 77 degrees
Check your work:
60 + 128 + 95 + 77 = 360
188 + 95 + 77 = 360
283 + 77 = 360
360 = 360

Graph the line . djdjej
Answer:
Step-by-step explanation:
The slope is 2 and the point (0,8) is on the graph. This means we have to plug this equation to y-y1=m(x-x1) where m is the slope. We know the slope and the we have the points (0,8) so we can completely fill in this equation. y-8=2(x-0) is equal to y-8=2x. You want to isolate y so you have to add 8 to both sides. y=2x+8. The graph y=2x+8 will look like this.

B is the answer to your question. have a nice day/evening
Three boys spent the afternoon playing a video game and then compared their best scores. Al says, "My best today is 1800 points more than yours, Bob." Carlo says, "I was having a good day. My 7200 points is 2/3 as much as your two scores combined, Al and Bob." How many points did each boy get in his best game that afternoon?
Answer:
Bob = 4500
Al = 6300
carlo = 7200
Step-by-step explanation:
the following equations can be derived from the question
A = B + 1800 equation 1 or A - B = 1800
C = 7200 = 2/3 (A + B) equation 2
where A = Al's score
B = Bob's score
C = Carlo's score
Make A + B the subject of the formula in equation 2
A + B = 10,800 equation 3
subtract equation 1 from 3
2B = 9000
B = 4500
Substitute for B in equation 1
A = 4500 + 1800 = 6300

Find the values of x and y that make these triangles congruent by the HL Theorem.
Answer:
x = 3 ; y=2
Step-by-step explanation:
to simplify the work we can build a system of two equations
2x+3 = 3y+3
x = y+1
we can now substitute the value of x in the first equation
2(y+1)+3 = 3y+3
2y + 2 + 3 = 3y+3
2y + 5 = 3y+3
y = 2
now we can subisitute the value of y in the first equation
x = 2 + 1 = 3

Find the area of a circle with radius 8yd.
Use the value 3.14 and do not round your answer.
Be sure to include the correct unit.
Answer:
Area of a circle = 200.96 yd²
Step-by-step explanation:
Area of a circle = πr²
Radius, r = 8 yd
π = 3.14
Area of a circle = πr²
= 3.14 * (8 yd)²
= 3.14 * 64
= 200.96 yd²
Area of a circle = 200.96 yd²

Step-by-step explanation:
Review the graph of function h(x).
What is lim h(x), if it exists?
Answer:
0
Step-by-step explanation:
because you have to look at what both sides of the graph is doing as it approaches 2.
from the left, we can see the the graph is going down All the way to 0 at x=2.
and from the right side, the graph is going up to 0 at x=2.
therefore the graph is approaching 0.
The limit of h(x) as x tends to 2 is equal to 0.
How to get the limit of h(x) when x tend to 2?
Remember that a limit is not the same as an evaluation, the limit studies the behavior of the function near the value, not in x = 2.
While we can see that h(2) = 3 (we have a jump there). We can see that around x = 2 the function tends to zero.
From that, we conclude that:
[tex]\lim_{x \to \ 2} h(x) = 0.[/tex]
Then the correct option is the first one.

There are 8 red marbles, 5 blue marbles, 11 green marbles, 1 yellow marble in a jar. Suppose one marble is selected at random. P(red, green or yellow)
Given:
Number of red marbles = 8
Number of blue marbles = 5
Number of green marbles = 11
Number of yellow marbles = 1
One marble is selected at random.
To find:
The P(red, green or yellow).
Solution:
Number of red, green or yellow marbles = 8 + 11 + 1
= 20
Total number of marbles = 8 + 5 + 11 + 1
= 25
The probability of getting a red, green or yellow marble is:
[tex]P(\text{red, green or yellow})=\dfrac{\text{number of red, green or yellow marbles}}{\text{Total number of marbles}}[/tex]
