Solve the system of equations below by graphing both equations with a
pencil and paper. What is the solution?
y=2x-3
y=-2x + 5
A. (-2,-7)
B. (2,-3)
C. (-2,5)
D. (2,1)
2x-3 = -2x + 5
4x = 8
x = 2
y = 2*2 - 3 = 1
(2 ; 1)
you have to draw the 2 lines
the solution will be the intersection point of the 2 lines
Answer:
[D] (2,1)
Step-by-step explanation:
Given;
y=2x-3
y=-2x + 5
Solve;
y = 2x - 3 . . . [Equation 1]
y = -2x + 5 . . . [Equation 2]
[Equating 1 and 2]
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1
Solution = (2, 1)
Hence, Answer = [D] (2,1)

Identify which quadrant contains the terminal side of an angle in standard position with each given degree measure. 75° 120° –30° –200°.
Answer:
75° quadrant 1
120° quadrant 2
-30° quadrant 4
-200° quadrant 2
The measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Angles in standard position are measured in a counterclockwise direction from the positive x-axis.
An angle of 75° is less than 90° and lies between the positive x-axis and the positive y-axis, so it is in Quadrant I.
An angle of 120° is greater than 90° and less than 180°, so it is between the positive y-axis and the negative x-axis, which means it is in Quadrant II.
An angle of -30° is equivalent to a 330° angle (360° - 30°) and lies in Quadrant IV because it is less than 360° and greater than 270°.
An angle of -200° is equivalent to a 160° angle (360° - 200°) and lies in Quadrant III because it is greater than 90° and less than 180°.
Hence, the measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.

[tex]C = \frac{1}{4}n( \: a(1) \: + \: a(2) \: ) \\ [/tex]
Multiply sides by 4
[tex]4 \times C = 4 \times \frac{1}{4}n( \: a(1) + a(2) \: ) \\ [/tex]
[tex]4C = n( \: a(1) + a(2) \: )[/tex]
Divided sides by n
[tex] \frac{4C}{n} = \frac{n}{n}( \: a(1) + a(2) \: ) \\ [/tex]
[tex] \frac{4C}{n} = a(1) + a(2) \\ [/tex]
Subtract sides - a (2)
[tex] \frac{4C}{n} - a(2) = a(1) + a(2) - a(2) \\ [/tex]
[tex] \frac{4C}{n} - a(2) = a(1) \\ [/tex]

please help!! If y = sin x, then dy/dx =
Answer:
the answer is option B
Step-by-step explanation:
To find dy/dx the equation here is
first multipled by derivative of second + second multipled by derivative of first
y = x*sinx
dy/dx = x * derivative of sinx + sinx * derivative of x
derivative of x with respect to x is 1
derivative of sinx with respect to x is cosx
therefore
dy/dx = x * cosx + sinx * 1
= x * cosx + sinx
The perimeter of a square is 24 inches. Complete the equation and solve to find the length of each side, s.

A parabola opening up or down has vertex (4, -1) and passes through (-9, -181/12). Write its equation in vertex form
Answer:
y = -1/12(x -4)² -1
Step-by-step explanation:
The vertex form equation for a parabola is ...
y = a(x -h)² +k . . . . . . vertex (h, k); vertical scale factor 'a'
The vertex coordinates are given. To find the scale factor, we substitute the given point.
-181/12 = a(-9 -4)² -1 . . . . . substitute the given values into the equation
-181/12 = 169a -1 . . . . simplify a bit
-169/12 = 169a . . . . add 1
a = -1/12 . . . . . . . multiply by 1/169
The vertex form equation of the parabola is ...
y = -1/12(x -4)² -1

What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
Types of the polygon are as follows;
Convex polygon - In this polygon, all angles are less than 180 degrees. And it may be regular or irregular in shape. The diagonal does not intersect the sides of the polygon.Concave polygon - In this polygon, one angle is greater than 180 degrees. And it is generally irregular in shape. The diagonal intersects the sides of the polygon.The 6 sided polygon is called a hexagon and the polygon is an irregular concave hexagon.

A bag contains 6 red, 5 yellow, and 3 black marbles. You select one
marble at random. What is the probability that it is a red or black
marble?
Answer:
The probability that it is a red or black marble is 0.6429, or 64.29%
Step-by-step explanation:
Frequentist Probability
The probability of an outcome is defined as the frequency of the number of ways the outcome occurs relative to the number of ways that it could have occurred.
The equation to calculate the probability is:
[tex]\displaystyle P(A)=\frac{m}{n}[/tex]
Where m is the number of ways the event A can occur and n is the total number of ways it could have occurred.
The bag contains 6 red, 5 yellow, and 3 black marbles. If one of them is randomly selected, it can be of any color from a total of n=6+5+3=14
Event A consists of the marble being red or black. It can be taken from m=6+3=9 marbles.
The probability is:
[tex]\displaystyle P(A)=\frac{9}{14}=0.6429[/tex]
The probability that it is a red or black marble is 0.6429, or 64.29%
