Use coordinate pair to find u(2)
Answers
Answer:
[tex]u(2) = 3[/tex].
Step-by-step explanation:
A function [tex]f: A \to B[/tex] is a set of ordered pairs ([tex]2[/tex]-tuples in the form [tex](a,\, b)[/tex]), such that for any [tex]a \in A[/tex], there is exactly one [tex]b \in B[/tex] such that [tex](a,\, b) \in f[/tex].
In other words, for any element [tex]a[/tex] in the domain of this function, there must be exactly one ordered pair with this [tex]a\![/tex] as the first element.
If [tex]f[/tex] meets these requirements, then for any [tex]a \in A[/tex] and [tex]b \in B[/tex], write [tex]f(a) = b[/tex] if and only if [tex](a,\, b) \in f[/tex].
In other words, write [tex]f(a) = b[/tex] ([tex]f[/tex] maps [tex]a[/tex] to [tex]b[/tex]) if and only if there is an ordered pair in [tex]f\![/tex] with [tex]a\![/tex] as the first element and [tex]b\![/tex] as the second element.
The [tex]u[/tex] in this question is indeed a set of ordered pairs and meet the requirements for being a function from [tex]\lbrace 1, 2, 3\rbrace[/tex] to [tex]\lbrace 2,\, 3,\, 4 \rbrace[/tex].
The question is asking for the value of [tex]u(2)[/tex]. Thus, it would be necessary to find an ordered pair in [tex]u[/tex] with [tex]2[/tex] as the first element.
The only ordered pair in [tex]u[/tex] with [tex]2[/tex] as the first element is [tex](2,\, 3)[/tex]. Thus, [tex]u\![/tex] maps [tex]2\![/tex] to [tex]3\![/tex], such that [tex]u(2) = 3[/tex].

(5x2-13x - 28) + (x – 4)
Answers
Factor the expression
(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5 and x = 4 are the two factors of the given polynomial.
What is a factor of a polynomial ?The factors of a polynomial are those values of x for which the given polynomial satisfies.
According to the given question we have to divide a polynomial (5x² - 13x -28) by (x - 4).
(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).
(5x² - 13x -28)/(x-4) = (x-4)(5x+7).
So, the obtained factor is (5x+7) = 0.
∴ 5x + 7 = 0
5x = -7
x = -7/5 is a factor of the given polynomial and by substituting these value in x.
(5x² - 13x -28)
5(-7/5)² - 13(-7/5) - 28 = 0
5(49/25) + 91/5 - 28 = 0
49/5 + 91/5 - 28 = 0
140/5 - 28 = 0.
28 - 28 = 0
0 = 0 ( hence satisfied that -7/5 is a factor of the given polynomial ).

Find the value of X. Show your work.
Answers
Answer:
x = 3
Step-by-step explanation:
The traingels are similar so we can conpare sides.
3 is to 18 as 2 is to 4x or
3/18 = 2/4x
1/6 = 1/2x
6 = 2x
3 = x
x = 3
Step-by-step explanation:
The triangle in the left is dilated 3 times bigger than the triangle in the right
that means that the left triangle is 3 times larger. In order to solve for x, you must compare one side from the left triangle to the other side of the right triangle.
so…
since the hypotenuse of the left triangle is 18, the hypotenuse of the right triangle is 3. 18 to 3 is 6 because 18 divided by 6 is 3.
And from 15 to 2 1/2 is 6 as well. (Use your calculator if you need to). so with all that information, x = 3 because…
4x > 2
and since the right triangle is 3 times larger…
4(3) > 2
12 > 2
and that means that 12 to 2 is 6
Therefore, the value of x is 3
