A) [tex]-\frac{7}{4}[/tex]
Step-by-step explanation:
For this question, we can use the rise over run method, which means y over x.
So count how many it takes for the point on top to get to the bottom by x and y.
It takes 7 spaces down (y) and 4 spaces to the right (x)
So do rise over run and we get
[tex]\frac{7}{4}[/tex]
Meaning that B and C are incorrect. Now what about A and D?
Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.
[tex]-\frac{7}{4}[/tex]
A. is correct.

2 2/7 cm
5 1/6 cm
Answers
Answer:
11 17/21 cm²
Step-by-step explanation:
Given
Length = 2 2/7cm
Width = 5 1/6cm
Area of the rectangle = Length * width
Area of the rectangle = 2 2/7 * 5 1/6
Area of the rectangle = 16/7 * 31/6
Area of the rectangle = (16*31)/(7*6)
Area of the rectangle = 496/42
Area of the rectangle = 11 34/42
Area of the rectangle = 11 17/21
Hence the Area of the rectangle is 11 17/21 cm²
A line with a slope of 3 passes through the point (2, 4). What is the y-intercept of the line?
Answers
Answer:
y-intercept = -2
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1})[/tex]
y - 4 = 3(x - 2) Now change the equation to slope-intercept form
y - 4 = 3x -6
y = 3x - 2 So m = 3 b = y-intercept = -2
3x-3y= 4
-3x+3y= 3
how do i solve this equation using the elimination method?
Answers
Step-by-step explanation:
3x-3y=4
3y= 3x -4
y= x-4/3
-3x+3y=3
3y= 3x+3
y= x +1
.....
Since they have the same slope and different y-intercepts , then there are no solutions for these equations because they're parallel.

Answer:
the second one
Step-by-step explanation:
in order for it to be a function the x values CANNOT repeat.
in answer a the x value -6 repeats so that cannot be a function
in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \
b is the only one that does have repeating x values therefore it is the second one

Answers
9514 1404 393
Answer:
-8.21°
Step-by-step explanation:
The horizontal and vertical components of the forces are ...
(120; 30°) = (103.923, 60}
(200; -30°) = (173.205, -100}
Then the resultant is ...
(103.923 +173.205, 60-100) = (277.128, -40)
and the resultant direction is
arctan(-40/277.128) = -8.21°

Additional comment
The semicolon in (A; β) signifies the ordered pair is polar coordinates (magnitude; angle). The comma in (x, y) signifies the ordered pair is rectangular (Cartesian) coordinates. This notation is borrowed from the GeoGebra app, a geometry graphing/calculating program. It avoids some confusion. Personally, I prefer the notation A∠β to signify a magnitude and direction in polar coordinates.

Evaluate and simplify the following complex fraction.
Answers
=========================================================
Explanation:
The fraction 6/(-7) is the same as -6/7
We have the two fraction -6/7 and 3/11 being divided
The denominators are 7 and 11 respectively.
The LCM of those two numbers is 77 since 7*11 = 77
If we multiply each of those fractions (-6/7 and 3/11) by 77, then we'll clear out those inner denominators to simplify this complex fraction into a nicer one.
77*(-6/7) = -66
77*(3/11) = 21
This means the original complex fraction becomes -66/21
We can further simplify this by dividing each part by the GCF 3
-66/3 = -22
21/3 = 7
Therefore, the final answer is -22/7
