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]

In Exercises 9-12, tell whether the lines through the given points are parallel, perpendicular, or neither. Justify your answer 12. Line 1: (10, 5), (-8, 9) Line 2: (2, -4), (11, -6)
Answer:
They're parallel.
Step-by-step explanation:
The reason they're parallel is because they both have the same slope.
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].

Use long division to divide and use the result to factor the dividend completely.
(5x2-13x - 28) + (x – 4)
(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 ).

How can you find the unit rate?
Answer:
Understand unit rate. The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.
Look at the data. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.
Rewrite the data as a division problem.

Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0)

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

if tanA/2=4/3, find The value of sinA, cosA
given :- tanA=4/3
we already know that tanA=P/B
From Pythagorean theorem we get..
H²=P²+B²
H²=4²+3²
H²=16+9
H²=25
H²=5²
H=5
SinA=P/H
CosA=B/H
from that
SinA= 4/5
CosA=3/5

A: 39 1/5 km
C:4/5km
B:1 1/5km
D 4/35km
Eli chose A as the correct answer. How did he get that answer?
Answer:
Jeremy swims 4/5 of a kilometer each day.
Step-by-step explanation:
Since 5 3/5 can be turned into 28/5, then divided by 7/1, you will get 4/5. So Jeremy swims 4/5 of a kilometer each day.
Eli got his answer by multipying 5 3/5 by 7 which was an incorrect process.
