The required domain is [tex]\{-3,5,7\}[/tex].
Given:
A set of ordered pairs is:
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
To find:
The domain of the given set of ordered pairs.
Solution:
Domain is the set of input values.
In the set of ordered pairs [tex](x,y)[/tex], then the set of all the [tex]x[/tex]-values is domain and the set of all the [tex]y[/tex]-values is range.
We have,
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
In the above set of ordered pairs, the x-values are [tex]-3,5,7[/tex].
[tex]Domain=\{-3,5,7\}[/tex]
Therefore, the domain of the given set of ordered pairs is [tex]\{-3,5,7\}[/tex].

Prove: [tex]\frac{a}{b}[/tex] = \frac{c}{d}[/tex], then[tex]\frac{a+b}{b} = \frac{c+d}{d}[/tex]. show work pls :)
Step-by-step explanation:
[tex]\dfrac{a}{b} = \dfrac{c}{d}[/tex]
Add 1 to both sides of the equation:
[tex]\dfrac{a}{b} + 1 = \dfrac{c}{d} + 1[/tex]
Note that
[tex]\dfrac{a}{b} + 1 = \dfrac{a + b}{b}[/tex]
Likewise,
[tex]\dfrac{c}{d} + 1 = \dfrac{c + d}{d}[/tex]
Therefore,
[tex]\dfrac{a + b}{b} = \dfrac{c + d}{d}[/tex]

A line perpendicular to the above line would have a slope of
Please Help!!
Answer:
Explanation :
The slope of the line with the equation -8x - 5y= -10 is -8/5 so the line parallel to it will have a slope of -8/5 because parallel limes have the same slope.
The line perpendicular to it will have a slope of 5/8. This is because the slopes of perpendicular lines add up to -1.

Find the equation of the line perpendicular line displayed below that passes through the point (-3,2). Explain your process. Express your answer in point-slope form
9514 1404 393
Answer:
y -2 = 1/4(x +3)
Step-by-step explanation:
Process: find the negative reciprocal of the slope of the line shown and put the appropriate values into the point-slope equation.
__
The slope of the given line can be found as the ratio of rise to run between the marked points.
m = rise/run = -8/2 = -4 . . . . counting grid squares
The desired line has a slope that is the opposite reciprocal of this:
m' = -1/m = -1/-4 = 1/4
The point-slope equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Then the desired line with slope 1/4 through point (-3, 2) has equation ...
y -2 = 1/4(x +3)

Using the Principle of Mathematical Induction, prove that . n ^2 − n is even for n ≥ 1
Base case: if n = 1, then
1² - 1 = 0
which is even.
Induction hypothesis: assume the statement is true for n = k, namely that k ² - k is even. This means that k ² - k = 2m for some integer m.
Induction step: show that the assumption implies (k + 1)² - (k + 1) is also even. We have
(k + 1)² - (k + 1) = k ² + 2k + 1 - k - 1
… = (k ² - k) + 2k
… = 2m + 2k
… = 2 (m + k)
which is clearly even. QED
