Step-by-step explanation:
Choose the graph that solves this system of equations.
y = 2x – 6
y = –4x + 3
Two lines that intersect at the origin. One line has a positive slope and the other has a negative slope. Two lines that intersect at about 2 comma negative one half. One line has a positive slope and the other has a negative slope. There is also a single dot at the origin. Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope. Two lines that both have a positive slope. They do not intersect on the part of the graph shown, but there is a single dot at the origin.
Answer: Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope.
Step-by-step explanation:
Given equations of line:
y = 2x – 6 ...(i)
y = –4x + 3 ...(ii)
On comparing with y=mx+c (slope-intercept form), where m= slope ,= y-intercept.
(i) has positive slope (2) and (ii) has negative slope(-4).
Eliminate (ii) from (i), we get
0 = 6x-9
⇒ 6x=9
⇒ [tex]x=\dfrac32[/tex]
Put value of x in (i), we get
[tex]y=2(\dfrac32)-6\\\\\Rightarrow\ y=3-6=-3[/tex]
Point of intersection = (three halves, negative 3)

What is the formula for the sum of the interior angle measures of a polygon?
Answer:
(n-2)x 180 degrees
Step-by-step explanation:
Evaluate and simplify the following complex fraction.
=========================================================
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

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
Two pools are being filled with water. To start, the first pool contains 1900 liters of water and the second pool contains 1529 liters of water. Water is being added to the first pool at a rate of 21.5 liters per minute. Water is being added to the second pool at a rate of 34.75 liters per minute.
After how many minutes will the two pools have the same amount of water?
How much water will be in each pool when they have the same amount?
Answer:
after 36 minutes the two pools will have the same amount of water.
2110 liters of water would be in each pool when they have the same amount.

D {(3,5), (1,9), (-5, -6), (4,9)}
Answer:
C
Step-by-step explanation:
Because 0 repeats
The answer is C, because the 0 repeats itself in C and in a function, X does NOT repeat. And in this case, X is 0, which repeats.
Martha compro un perfume cuyo precio de lista es de $400. Al llegar ala caja pago $300,¿cuál fue el porcentaje de descuento?
Answer:
Es de 75% de descuento
Step-by-step explanation:
400 = 100
200 =50
100 = 25
200+100=300
50+25=75
300 = 75
solve the inequality -2z - 3 < 5
-2z - 3 < 5 inequality is solved to z>-4.
What is Inequality?Relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is -2z - 3 < 5
Minus two times of z minus three less than five.
-2z - 3 < 5
We need to solve this inequality, which means we need to solve of variable z.
Add 3 on both sides of inequality
-2z<8
Divide both sides by 2
-z<4
Multiply the given inequality by minus
z>-4
Hence, -2z - 3 < 5 inequality is solved to z>-4.

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.

A line with a slope of 3 passes through the point (2, 4). What is the y-intercept of the line?
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

Work out the area of the rectangle using a calculator and
giving your answer as a mixed number.
2 2/7 cm
5 1/6 cm
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
Two forces, one of 120 pounds and the other of 200 pounds, act on the same

the direction of the resultant of these two forces.

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°

The polar coordinates (A; β) can be translated to rectangular coordinates by ...
(A; β) = (A·cos(β), A·sin(β))
__
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.
