Step-by-step explanation:
how do you get the slope
Answer:
See below
Step-by-step explanation:
The way to find the slope is to find how many blocks/number it went up and to the side. The number of blocks it went up on the y-axis, in this case, is 3 and it went along the x-axis once. In order to actually find the slope, you need to put the y over the x. So, 3/1 is equal to three, so the slope of this line is 3
Answer:
y2-y1/x2-x1
Step-by-step explanation:
For instance, say you have points (3,2) and (4,6) on a line.
x1 = 3, y1 = 2, x2 = 4, y2 = 6
6 - 2/4 - 3
4/1
slope = 1
I'm confused on this problem 2/3x-1=5
Answer:
x=9
Step-by-step explanation:
2/3x-1=5
Add 1 to each side
2/3x-1+1= 5+1
2/3x = 6
Multiply each side by 3/2
2/3x*3/2 = 6*3/2
x = 9
Answer:
x=9
Step-by-step explanation:
You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

Answer:
AOB = -8x + 68
Step-by-step explanation:
AOC = 40°
BOC = 8x - 28
Angle Addition Theorem:
AOB + BOC = AOC
AOB + (8x - 28) = 40
AOB + (8x - 28) + 28 = 40 + 28
AOB + 8x - 8x = 68 - 8x
AOB = -8x + 68
AOB + BOC = AOC
(-8x + 68) + (8x - 28) = 40
-8x + 8x + 68 - 28 =40
0x + 40 = 40
40 = 40
In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?
Answer:
An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.
They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.
An echo is an unpleasant sound heard after a produced sound got reflected from a plain surface. It is majorly eliminated in a cinema theater by:
the use of sound absorbing materials in the construction of the wallsabsorption of sound waves by the body and cloths of viewers
Echo is a sound produced due to the reflection of a produced sound by a plain surface. Its continuous occurrence leads to reverberation. It causes distortion of produced sound which makes it unpleasant to hearing. Thus the need for a mechanism which would reduce it to a bearable level.
To reduce or eliminate echo, the walls of the cinema theater had been constructed with sound absorbing materials which may include special pads. These would have been incorporated into the walls, and would absorb most unwanted sounds produced in the theater.
Also the cloths worn by viewers absorbs some of the unwanted sound, thus assisting to indirectly reduce echo.

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites
Answer:
h = 59 hours
Step-by-step explanation:
Total earnings = fixed charge + variable charge
Fixed charge = $65
Variable charge = $15h
Where, h = number of hours
Total earnings = $950
Total earnings = fixed charge + variable charge
950 = 65 + 15h
Subtract 65 from both sides
950 - 65 = 65 + 15h - 65
885 = 15h
Divide both sides by 15
h = 885 / 15
= 59
h = 59 hours

Answer:
x=9
Step-by-step explanation:
First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.
You then come up with 13.5=1.5x
Divide both of them by 1.5 and then you get x=9
Answer:
X=9
Step-by-step explanation:
Okay first Hello! :)
so, B is the mid point of the segment midpoint means the half way
so, if AB= 5x+18 is the half to get the whole you would need to times it by 2
you get 10x+36
so now you equal them together
10x+36= 13x +9
Always move your smaller x, and now you got
3x+9=36
move your 9 over and switch the sign you get
3x=27
divide by three and you get
X=9

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey’s work?
Kailey is correct: 89.12 times 10 Superscript 5 equals 8,912,000.
Kailey is not correct: the exponent of ten should be negative.
Kailey is correct: it is written as a decimal number multiplied by a power of ten.
Kailey is not correct: 89.12 times 10 Superscript 5 is not written in scientific notation.
Answer:
kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation
Step-by-step explanation:
8.912 times 10 superscript 5 is written is scientific notation
The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.
How to determine the true statement?From the question, Kailey's expression can be represented as:
8,912,000 = 89.12 * 10^5 in scientific notation
To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9
The number of zero is 6.
So, the scientific notation of the number is
8,912,000 = 8.912 * 10^6
This means that Kailey's expression is not correct
Hence, the true statement is (d)

Evaluate 3ab for a=2 and b=3
Answer:
18
Step-by-step explanation:
For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.
a = 2; b = 3
3ab
Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.
3ab = 3 * a * b
With this in mind, let's plug in the values of a and b into the expression.
3ab
= 3 (2) (3)
= 3 (6)
= 18
Hence, 3ab evaluated when a=2 and b=3 is 18.

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG
