(2,9)(3,4)(-2,5) is this a function
Answer:
Not a function
Step-by-step explanation:
when plotted the points do not form a line
Answer:
no its not a function
Explanation:
A function is a relation (a set of ordered pairs) with the additional property that: no two pairs have the same first element and different second elements.
The definition is often stated as: A relation in which every x value is associated with exactly one y value. "Exactly one means one but two or more:
{(1,2);(2,3);(3,4);(2,5)} includes the points (2,3) and (2,5). Therefore these set of pairs are not a function.
NEED HELP !! give the following information about the linear function on the graph shown.
Answer:
x-intercept = 6
y-intercept = -4
Slope: m = ⅔
f(3) = -2
Step-by-step explanation:
✔️The x-intercept is the value of x when y = 0. It is the point at which the line of the function intercepts the x-axis. Thus,
x-intercept = 6
✔️The y-intercept is -4. At this point, x = 0. The line intercepts the y-axis at y = -4. Thus,
y-intercept = -4
✔️Slope can be calculated using two points, (0, -4) and (6, 0).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-4)}{6 - 0} = \frac{4}{6} = \frac{2}{3} [/tex]
Slope: m = ⅔
✔️f(3) means, what is the value of y when x = 3.
From the graph, when x = 3, y = -2.
Therefore,
f(3) = -2
A city council consiste of 8 democrats and 6 republicans. If a committee of 4 people is selected,find the probability of selecting 2 democrats and 2 republicans
Answer:
Step-by-step explanation:
8C2 * 6C2
============
14C4
8C2 = 8*7/1 * 2 = 28
6C2 = 6*5 / 1*2 = 15
14C4 = 14*13 *12 * 11 / (1 * 2 * 3 * 4) = 1001
28 * 15 / 1001 = .4195
f (x) = –2x+1
If
f (x) = 11

you have to write an equation
Answer:
c=100g+50
Step-by-step explanation:
c is the total cost
there is a 50 dollar fee and 100 dollars per guest
so for every guest, the cost is increased by 100
since there are g number of gusts, the price for the guests will be 100g dollars
since there is also a 50 dollar fee, 50 dollars has to be added to the 100g
therefore c=100g+50

5. What is the solution to the system of equations?
Answer:
4. The solution to the system of equations is: (2,-1)
5. The solution to the system of equations is: (3,5)
Step-by-step explanation:
4. What is the solution to the system of equations?
[tex]2x+3y=1\\-3x+4y=-10[/tex]
Let:
[tex]2x+3y=1--eq(1)\\-3x+4y=-10--eq(2)[/tex]
Multiply eq(1) by 3 and eq(2) by 2 and add both equations
[tex]6x+9y=3\\-6x+8y=-20\\---------\\0x+17y=-17\\y=\frac{-17}{17}\\y=-1[/tex]
So, value of y=-1
Now finding the value of x bu putting value of y in eq(1)
[tex]2x+3y=1\\2x+3(-1)=1\\2x=1+3\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, value of x=2
The solution to the system of equations is: (2,-1)
5. What is the solution to the system of equations?
[tex]y=2x-1\\6x-y=13[/tex]
Let:
[tex]-2x+y=-1--eq(1)\\6x-y=13--eq(2)\\------\\4x=12\\x=\frac{12}{4}\\x=3[/tex]
So, value of x=3
Putting value of x in equation 1 to find value of y
[tex]y=2x-1\\y=2(3)-1\\y=6-1\\y=5[/tex]
So, value of y=5
The solution to the system of equations is: (3,5)
Which inequalities have no solution? Check all of the boxes that apply. 1. x > x 2. –3x –3x 3. –4 + x > –2 + x 4. x – 2 < x + 3
Answer:
1, 3
Step-by-step explanation:
1. x > x
Technically, one number cannot be more than itself. It can only equal to itself.
3. –4 + x > –2 + x
If you minus x from both sides of the equation, it becomes:
-4 > -2
This is not true no matter what x is, thus it has no solution.
4. x – 2 < x + 3
If you add 2 on both sides, it becomes:
x < x + 5
This inequality is possible and has infinitely many solutions.
Note: I will update this answer and address Question 2 once the inequality sign is given :)

Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ([tex]\sqrt{x}[/tex] this symbol). When you do that, you should get what x is! Let me know if you still need help!
A triangle has sides which are consecutive odd integers and an
angle of 120°. What is the perimeter of the triangle?
Answer:
Perimeter = 15
Step-by-step explanation:
We are told that the length of each of the 3 sides of the triangle are consecutive odd integers.
Thus means that we can write the 3 terms as;
(x - 2), x, (x + 2)
Thus, perimeter is;
P = (x - 2) + x + (x + 2)
P = 3x
If an angle is 120°, it means that the corresponding side that is directly opposite the angle is the largest side of the triangle.
Thus, this side is (x + 2)
Using cosine rule, we have;
(x + 2)² = x² + (x - 2)² - 2(x(x - 2))cos 120
Expanding, we have;
x² + 4x + 4 = x² + x² - 4x + 4 - (2x² + 4x)(-½)
This reduces to;
4x = x² - 4x + x² - 2x
2x² = 10x
2x = 10
x = 10/2
x = 5
Thus, other sides are;
(x - 2) = 5 - 2 = 3
And (x + 2) = 5 + 2 = 7
So,perimeter is;
P = 3x = 3 × 5 = 15
write an equivalent system of equations to the following of equations: 2x+2y=-6 and x-4y=2
Answer:
A system of equivalent equations is:
x + y = -3
2x - 8y = 2
Step-by-step explanation:
Given
2x + 2y = -6
x - 4y = 2
Required
Write a system of equivalent equations
A system of equivalent equations implies that:
When the new set of equation is solved, the solution is equivalent to the original equation.
To do this, we have to carry out the same operation on both sides of the given equation.
Take for instance
2x + 2y = -6
Multiply both sides by ½
½(2x + 2y) = -6 * ½
x + y = -3
x + y = -3 is equivalent to 2x + 2y = -6
Multiply both sides of x - 4y = 2 by 2
2(x - 4y) = 2 * 2
2x - 8y = 4
2x - 8y = 4 is equivalent to x - 4y = 2
Hence, a system of equivalent equations is:
x + y = -3
2x - 8y = 2
Note that there are more equivalent equations.
The results you get depend on the operation performed on the given equation.
