Given:
The set of ordered pair (-4,2), (3,6), (4,3), (?,?).
To find:
The ordered pairs that could not be included in this set if its a function.
Solution:
We know that, a relation or a set of ordered pairs is a function if there exist a unique output (y-value) for each input (x-value).
If (-4,-3) point is included in the given set of ordered pair, then we have [tex]y=-3,2[/tex] for [tex]x=-4[/tex].
Since there are more than one output value at [tex]x=-4[/tex], therefore the given set of ordered pairs will not be a functions after including the point (-4,-3).
If points (1,2), (3,6) and (-3,6) are included in the given set of ordered pair, then there exist a unique output for each input.
So, the given set of ordered pairs will be a functions after including the points (1,2), (3,6) and (-3,6).
Therefore, the correct option is A.

Assuming that no denominator equals zero, which expression is equivalent to (n^2-7n+12)/(n-3)(n+4)
Answer:
D
Step-by-step explanation:
took the test
The expression is equivalent to (n² - 7n + 12) is (n-4)/ (n+4).
The correct option is D.
What is Expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
Expression: (Math Operator, Number/Variable, Math Operator)
We have,
(n² - 7n + 12) / (n-3)(n+4)
So, Factorizing (n² - 7n + 12)
= (n² -3n - 4n +12)
= n(n-3)- 4(n-3)
= (n-3)(n-4)
Then, (n² - 7n + 12) / (n-3)(n+4)
= (n-3)(n-4)/ (n-3)(n+4)
= (n-4)/ (n+4)

Please help me with this
Answer:
90,45,45
Step-by-step explanation:
it a system of equations
say that x y and z are each angles of the triangle
that means that they add up to 180 so x+y+z=180
the question says that two of the angles in the triangle are equal so we can just say that x=y
and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z
x+y+z=180
x+y=z
x=y
we start with the first two equations:
since x+y=z then we can substitute z in for x+y in the first equation
z+z=180
2z=180
z=90
and since x=y then
x+x=z
2x=90
x=45
y=45
z=90
hope that helps :)

If I have an 86% overall grade in a class and score 40% on a test, what will my grade come out as?
Answer:
It really depends on how much percent of your overall grade tests count as. But, usually they count for about 60% of your grade (depending on what grade you are in). You have about 65% at the lowest and a 75% at the highest. But, I'm just going by what my school does, I don't know how your school grades tests.

Equivalent fractions 1/3
Answer:
2/6; 3/9
Step-by-step explanation:
Multiply both the numerator and the denominator by the exact same number to find equivalent fractions
For example, I will randomly choose to multiply both by 2
Example 1:
1 × 2 / 3 × 2
2/6
Now, I'll do 3
Example 2:
1 × 3 / 3 × 3
3/9
You can check your work by dividing both the numerator and the denominator by the original fraction (1/3) to see if you get the number 1
Example 1:
2/6 ÷ 1/3
Copy dot flip
2/6 × 3/1
2 × 3 / 6 × 1

What is the slope of the line whose equation is 2x – 4y = 9?
a) 1
2
c) 2
d) 3
solotion
Answer:
m = 1/2
Step-by-step explanation:
The given equation of line is :
2x – 4y = 9 ..(1)
We need to find the slope of the line. The general equation of a line is given by :
y = mx + c ..(2)
Where
m is the slope of line
Equation (1) can be rearranged as follow :
-4y = 9-2x
4y = -9+2x
or
4y = 2x-9
Divide both sides by 4.
[tex]\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})[/tex] ..(3)
Now comparing equation (2) and (3) we get :
[tex]m=\dfrac{1}{2}[/tex]
So, the slope of the line is 1/2.

A. (7,-1.5)
(10,-4).
B. (-2,6)
Find the coordinates of Naya's house.
C. (0,0)
Answer:
[tex](-2,6)[/tex]
Step-by-step explanation:
Given
[tex]Elena = (10,-4)[/tex]
[tex]Midpoint = (4,1)[/tex]
Required
Determine the coordinates of Naya's
Midpoint is calculated as:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
In this case:
[tex](x_1,y_1) = (10,-4)[/tex]
[tex](x,y) = (4,1)[/tex]
So, we have:
[tex](4,1) = \frac{1}{2}(10+x_2,-4+y_2)[/tex]
Multiply through by 2
[tex]2 * (4,1) = \frac{1}{2}(10+x_2,-4+y_2) * 2[/tex]
[tex](8,2) = (10+x_2,-4+y_2)[/tex]
By comparison:
[tex]8 = 10 + x_2[/tex]
[tex]2 = -4 + y_2[/tex]
So:
[tex]8 = 10 + x_2[/tex]
[tex]x_2 = 8 - 10[/tex]
[tex]x_2 = -2[/tex]
[tex]2 = -4 + y_2[/tex]
[tex]y_2 =2+4[/tex]
[tex]y_2 =6[/tex]
So, the coordinate is: [tex](-2,6)[/tex]
