Use coordinate pair to find u(2)
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].
Solving Exponential Equations and Inequalities Solve for x 169% = 13"
Answer:
x = 100/13
Step-by-step explanation:
x 169% = 13
x = 13/169%
x = 13/1.69 = 13/169/100
x = 13 × 100/169
x = 100=13
[tex]\\ \sf\longmapsto 169\%x=13[/tex]
[tex]\\ \sf\longmapsto 1.69x=13[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{13}{1.69}[/tex]
[tex]\\ \sf\longmapsto x=7.69[/tex]
Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0)
Answer:
B. y - 4 = - 1/2(x + 6)Step-by-step explanation:
Given points on the line:
(−6, 4) and (2, 0)Find the slope:
m = (0 - 4)/(2 - (-6)) = -4/ 8 = -1/2Point slope form using the first point:
y - 4 = - 1/2(x - (- 6)) ⇒ y - 4 = - 1/2(x + 6)Correct choice is B
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The required equation is :
[tex]\boxed{ \boxed{y - 4 = - \dfrac{1}{2} (x + 6)}}[/tex]
[tex] \large \boxed{ \mathfrak{Explanation}}[/tex]
Let's find the slope (m) ~

Which statement is true? 13/14=169/182 13/14<169/182 13/14>169/182
pls help me
Answer: 13/14 = 169/182
Step-by-step explanation:
If you do 13 x 182 = 2,366
And then do 14 x 169 = 2,366
Making both sides equal if you multiple the numerator by denominator using cross multiplication
The fraction number 13/14 is equal to the fraction number 169/182. Then the true statement is A.
What is Algebra?Algebra is the study of mathematical symbols, while logic is the manipulation of those icons.
The product is another name for it. If the same thing, n, is delivered to m different people, we merely multiply them.
The fraction number is given below.
⇒ 13/14 and 169/182
Multiply the fraction number 13/14 by 13 in numerator and denominator. Then the expression is written as,
⇒ (13 x 13)/(14 x 13)
⇒ 196 / 182
The fraction number 13/14 is equal to the fraction number 169/182. Then the true statement is A.

The diagram shows two parallel lines cut by a transversal.
If the measure of ∠3=(2y+20)∘ and the measure of ∠5=(210−4y)∘, what is the measure of ∠4 ?
Enter the correct answer in the box.
Answer:
∠4 = 110
Step-by-step explanation:
∠3 + ∠5 = 180 {Co-interior angles are supplementary}
2y + 20 + 210 - 4y = 180
2y - 4y + 20 + 210 = 180 {Combine like terms}
-2y + 230 = 180
Subtract 230 from both sides
-2y = 180 - 230
-2y = -50
Divide both sides by (-2)
y = -50/-2
y = 25
∠5 = 210 - 4y
= 210 - 4*25
= 210 - 100
∠5 = 110
∠4 = ∠5 {Alternate interior angles are equal}
∠ 4 = 110°
Answer:
Step-by-step explanation:
