The graph of which of the following equations contains the points (2,3) and (3,2)

Mathematics

Crazy boy [7]2 years ago

Answer:

y = 5 - x

Step-by-step explanation:

The graph of the equation that will contain the points (2, 3) and (3, 2) is the graph that has a slope value that is equivalent to the slope value of the line running through the two points.

Slope of the line running through (2, 3) and (3, 2):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 3}{3 - 2} = \frac{-1}{1} = -1.

Slope (m) = -1.

The equation, y = 5 - x , is given in the slope-intercept form, which means it has a slope value of -1. I.e. the term "-x" is equivalent to -1x. So therefore, the graph of the equation that contains the points (2, 3) and (3, 2) is y = 5 - x.

Write the equation in standard form for a circle that has a diameter with endpoints (8,0) and (-8,0)
riadik2000 [5.3K]

Answer:

x²+y² = 64

Step-by-step explanation:

The standard form of writing the equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius of the circle

Given the diameter of the circle with endpoints (8,0) and (-8, 0)

d = √(x2-x1)²+(y2-y1)²

d = √(-8-8)²+(0-0)²

d = √(-16)²

d = √256

d = 16

radius r = 16/2

r = 8

The centre of the circle will be the midpoint of the coordinates

M = (8-8/2, 0+0/2)

M = (0/2, 0/2)

M = (0,0)

Hence the centre is at (0,0)

Get the required equation

Recall that (x-a)²+(y-b)² = r²

Substitute the centre and the radius

(x-0)²+(y-0)² = 8²

x²+y² = 64

This gives the required equation

K, so when x=0, then y=-6
so it goes through the y axis (up and down line) at y=-6

now find the x intercepts, or where y=0
factoring we get P(x)=-1(x+2)(x+1)(x-1)(x-3)
so it goes through the y axis at x=-2, x=-1, x=1, and x=3
put those points
now, the function is 4th degree and the leading coefient is negative, so it starts from bottom left and ends at bottom right
so draw a graph starting from bottom left and going through those points and ending at bottom right
since they are all odd multiplicities, the graph goes through the points to the other side of x axis instead of bouncing off

see graph included (hand drawn)

if there are 200 questions and 4 marks for correct answers and -1 for incorrect answer and total marks is 250then what is the nu

The number of questions answered correctly = 90.

<h3>What is a system of linear equations?</h3>
  • A system of linear equations is a set of two or more linear equations.
  • Linear equations refer to the equations that involve two or more variables in the form of "ax + b".

Now,

Given:

  • Total number of questions = 200
  • Marks for correct answer = 4
  • Marks for incorrect answer = -1
  • Total marks = 250

To find : Number of correct answers = ?

Finding:

Now, assuming that the student attempted and answered all the questions,

  • Let the number of questions correctly answered be x and incorrectly answered be y.

Then,

  1. x + y = 200 (For number of questions) (eqn 1)
  2. and 4x - y = 250 (For the marks scored) (eqn 2)

Solving the system of linear equations:

For eqn 2, we get that y = 4x - 250

Substituting in eqn 1, we get:

=> x + 4x - 250 = 200

=> 5x = 250 + 200 = 450

=> x = 90

That is, the number of questions answered correctly = 90, the incorrect answers = 200 - 90 = 110.
