Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
What is the difference between the median number of electoral votes per state and the modal number (mode) of electoral votes?

North Carolina | 15
Texas | 34
Utah | 5
======================
A. 50
B. 10
C. 16
D. 11
Answer:
B. 10
Step-by-step explanation:
The median is the middle number, so to find it, we must list the numbers from smallest to largest :
5, 5, 8, 11, 15, 21, 27, 34, 55
The median is 15
The mode is what number occurs most often, which is 5.
The difference will be found by subtracting 5 from 15:
15-5=10
Answer:
10
Step-by-step explanation: you have to find the median number and subtract by 5
5,5,8,11,15,21,27,5
also the median is middle number subtract by 5 because it want the difference number of electoral votes per state
15-5=10

Answer:
-The distance:
[tex]d = 1[/tex]
Step-by-step explanation:
-To find the distance between points [tex](-8,-2)[/tex] and [tex](-7,-2)[/tex], you the distance formula:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2}}[/tex]
-Use the two given points [tex](-8,-2)[/tex] and [tex](-7,-2)[/tex] for the distance formula:
[tex]d = \sqrt{(-7 + 8)^{2} + (-2 + 2)^{2}}[/tex]
-Then, solve the formula:
[tex]d = \sqrt{(-7 + 8)^{2} + (-2 + 2)^{2}}[/tex]
[tex]d = \sqrt{(1)^{2} + (0)^{2}}[/tex]
[tex]d = \sqrt{1 + 0}[/tex]
[tex]d = \sqrt{1}[/tex]
[tex]d = 1[/tex]
So, the answer for the distance would be [tex]d = 1[/tex] .

Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain your reasoning.Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain your reasoning.
We would prefer to use a graphing calculator because it will give a more exact solution, because it is easier to read, and because it is faster to do.
How to find a solution of a system of linear equations?
There are multiple ways, one of them is by graphing the lines and seeing where the lines intersect.
Now, there are two ways of doing this, graphing by hand and using a graphing calculator.
There are cases where graphing by hand is enough, but is more time-consuming than using a graphing calculator. But there are cases where the intersection happens at a point with irrational values, these cases is really hard to find the solution in a graph by hand (as it can have mistakes and you can't zoom in). While if you used a graphing calculator, you could zoom is as much as you want, so you would get a really good estimation for the solution.

randy and sandy are brother and sister. Randy is three less than twice Sandy's age. Together, their ages equal twent-four. How old is Sandy?
Answer:
Sandy is 9 years old.
Step-by-step explanation:
R+S=24
R=2S-3
R=Randy, S=Sandy
Plug the value of R into the first equation.
2S-3+S=24
Now, simplify.
3S-3=24
Now, solve the equation for S. First add three to both sides.
3S=24+3=27
3S=27
Now divide both sides by 3.
S=9
Based on the information given, the age of Sandy will be 9 years.
The equation that can be used to solve the question will be:
R + S = 24 .... i
R = 2S - 3 ..... ii
Put equation ii into i
R + S = 24
2S - 3 + S = 24
3S = 24 + 3
3S = 27
S = 27/3
S = 9
Therefore, the age of Sandy will be 9 years.

A piece of duct measures 48 inches. When pieces are fitted together, 1 12
inches is lost connecting each successive length of duct. On the job 7 and
12 pieces of ducting are used. What, in inches is the total length of the
finished duct?
Answer:
A piece of duct measures 48 inches.
In each connection, we lost 1 1/2 inches (i guess that it is what you wanted to write)
Then:
If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them, so the number of connections is equal to the number of ducts minus two.)
So here we have 7 times 48 inches for the pieces, minus 5 times 1 1/2 in (i will write 1 1/2 = 1 + 0.5 = 1.5 in, so the math is easier) for the connections, the length is:
L = 7*48in - 5*1.5in = 328.5 inches.
for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:
L = 12*48in - 10*1.5in = 561 in
Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.5in of the new connection:
L = 561in + 328.5in - 1.5in = 888in

Required
Find Equivalent
From law of indices
[tex](\frac{1}{a})^{-x} = \frac{1}{(\frac{1}{a})^{x}}[/tex]
So,
[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{5})^{3}}[/tex]
Expand denominator
[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{5})*(\frac{1}{5})*(\frac{1}{5})}}[/tex]
[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{125})}}[/tex]
Split expression on the right and side
[tex](\frac{1}{5})^{-3} = 1/{(\frac{1}{125})}}[/tex]
Convert divide (/) to multiplication (*)
[tex](\frac{1}{5})^{-3} = 1*{(\frac{125}{1})}}[/tex]
[tex](\frac{1}{5})^{-3} = 1*125[/tex]
[tex](\frac{1}{5})^{-3} = 125[/tex]

O y-6 = {(x - 2)
Oy- 6 = {(x - 2)
O y +6 = }(x + 2)
Oy+6 = (x + 2)
Answer:
y + 6 = 5/2(x + 2)
Step-by-step explanation:
The equation of the line passing through given points in point-slope form is y + 6 = (5/2)(x + 2). The correct answer is an option (C).
What is the slope of the line?The slope of a line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
Using the given points (-2, -6) and (6, 14), we can calculate the slope as:
slope = (14 - (-6)) / (6 - (-2))
= 20 / 8
= 5/2
Now, we can use the point-slope form of a line:
y - y₁= m(x - x₁)
where m is the slope and (x₁, y₁) is the point on the line. We can choose either of the given points to be the point on the line. Let's choose (-2, -6).
So, the equation of the line in point-slope form is:
y - (-6) = (5/2)(x - (-2))
Simplifying this equation gives us:
y + 6 = (5/2)(x + 2)
Therefore, the equation of the line passing through given points in point-slope form is:
y + 6 = (5/2)(x + 2)
