Answer:
No, No, Yes, Yes
Step-by-step explanation:
We can simply substitute the pairs as x and y in the equation:
(5, 0)
7*5 + 5*0 = 35 + 0 = 35
[tex]35 \ne 9[/tex]
(-4, -3)
7*(-4) + 5*(-3) = -28 - 15 = -43
[tex]-43 \ne 9[/tex]
(2, -1)
7*2 + 5*(-1) = 14 - 5 = 9
[tex]9 =9[/tex]
(-3, 6)
7*(-3) + 5*6 = -21 + 30 = 9
[tex]9 = 9[/tex]

Solve the following system of equations using substitution.
1)y = 3x - 5
2)5x - 4y = -3
Answers
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
[tex]5x - 4y = -3[/tex]
[tex]5x - 4(3x-5) = -3[/tex]
[tex]5x -12x+20=-3[/tex]
[tex]-20[/tex] [tex]-20[/tex]
_______________
[tex]5x-12x=-23[/tex]
[tex]-7x=-23[/tex]
___ ____
[tex]-7[/tex] [tex]-7[/tex]
[tex]x=3.29[/tex] (rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
[tex]y = 3x-5[/tex]
[tex]y = 3(3.29)-5[/tex]
[tex]y = 9.87-5[/tex]
[tex]y = 4.87[/tex]
So, your final answer would be (3.29, 4.87).

Answers
Answer:
1 or -0.5±1.9365i
Step-by-step explanation:
We know that [tex]x^{3} - y^{3} = (x-y) ^{3} +3xy(x-y)[/tex]
So plug in x=a and y=1/a, (a-1/a)^3+3*a*1/a*(a-1/a)=4
Let a-1/a=k, k^3+3k=4, k=1 or a complex conjugate -0.5±1.9365i
That's the answer.

One of the limitations of using the range is that it is a _____________ measure of variability. It is ______________ susceptible to ______________. It is used mostly with ______________ or ordinal data.
Answers
Answer:
One of the limitations of using the range is that it is a simple but poor measure of variability. It is very susceptible to poor representation of data spread. It is used mostly with ordered data or ordinal data.
Step-by-step explanation:
The measure of the range of a set of given data can be established once the difference between the highest and lowest values is known.
The range is simple to use but only considers the smallest and largest data elements in the set without considering the middle values and other values that could influence results if the data spread is to be considered.
Ordinal data aren't numerical data. Examples include Time of day such as morning, noon, night.

A line contains the points (-6, -4) and (0, 4). What is the equation of this line in slope-intercept form? A. B. C. y = x – 4 D. y = x + 4
Answers
Answer:
y = 4/3 x + 4
Step-by-step explanation:
The general form of the equation of a line is given as
y = mx + c where m is the slope and c is the intercept on the y axis
where the slope m = (y2 - y1)/(x2 - x1)
Hence given the points (-6, -4) and (0, 4)
m = (4 --4) / (0 --6)
= (4+4)/(0+6)
= 8/6
= 4/3
For a line with given points (x1, y1), the equation is given as
y-y1 = m(x-x1)
Hence the equation of this line in slope-intercept form
y - -4 = 4/3(x --6)
y + 4 = 4/3(x + 6)
3y + 12 = 4x + 24
3y = 4x + 24 - 12
3y = 4x + 12
y = 4/3 x + 4
For a line with given points (x2, y2), the equation is given as
y-y2 = m(x-x2)
Hence the equation of this line in slope-intercept form
y-4 = 4/3(x - 0)
multiply through by 3
3y - 12 = 4x
3y = 4x + 12
y = 4/3 x + 4

Your mom deposits $3500 into an account that pays 4.75% annual interest compounded continuously. How many years will it take for the amount of money in the account to reach $15,000? Just enter a numerical answer for the number of years rounded to the hundredth place.
Answers
Answer:
About 31 years
Step-by-step explanation:
Given data
Principal= $3500
Rate= 4.75%
Final amount= $15,000
Time=??
The expression for time on compound interest is
Calculate time, solve for t
t = ln(A/P) / r
substitute
Calculate time, solve for t
t = ln(15000/3500) / 0.0475
t= ln(4.2857)/ 0.0475
t= 1.4552/0.0475
t= 30.63 years
Hence it will take about 31 years

two vertical poles of heights 12 inches and 22 inches are separated by a horizontal distance of 24 inches. what will be the distance between the tops of these poles?
Answers
Answer: 26 in.

Heights of Poles are [tex]12\ in., 22\ in.[/tex]
distance between them is [tex]x=24\ in.[/tex]
the difference in heights of the pole is [tex]y=22-12=10\ in.[/tex]
From the figure, using Pythagoras theorem, distance L is given by
[tex]\Rightarrow L^2=y^2+x^2\\\Rightarrow L^2=10^2+24^2\\\Rightarrow L^2=100+576=676\\\Rightarrow L=\sqrt{676}=26\ in.[/tex]

Answer:

Step-by-step explanation:
Answer:
5.1 x 102 in scientific notation
Step-by-step explanation:
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease. Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10bStep 1
step1: To find a, take the number and move a decimal place to the right one position.
Original Number: 510
New Number: 5.10
step 2: Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 1 0
Decimal Count: 1 2
Step 3: Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.1 (Please notice any zeroes on the end have been removed)
b = 2
Now the whole thing:
5.1 x 102
Step 4:
Check your work:
102 = 100 x 5.1 = 510

its an inequality eqution, i already know he can spend 30 or less on the boook
Answers
answer:
30 > 4x + 2 and 6 books
step-by-step explanation:
read the question and set up the inequalitylet x = number of books he can afford30 > 4x + 2
30 would be on one side since that's the most he can spend4x because each book is $4+ 2 because there is a charge of $230 > 4x + 2
28 > 4x
7 > x
he can afford 6 booksit cannot be 7 because if he does buy 7 books, it would cost more than $30(financial math) Elementary and Secondary Education is paid mostly from:
