Answer:
d. 18x^3-27x^2y
Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
Answer:
(d.) [tex]18x^3-27x^2y[/tex]
Step-by-step explanation:
When given the following equation,
[tex](3x)^2(2x-3y)[/tex]
Systematically perform the operations. Use the order of operations, the order of operations states the following,
1. Parenthesis
2. Exponents/ radicals
3. Multiplication/ Division
4. Addition/ Subtraction
Remember, when performing an exponential operation, one multiplies the base by itself the number of times the exponent indicates. In the given equation, perform the exponent by multiplying the base (3x) by itself twice.
[tex](3x)^2(2x-3y)\\\\(3x)(3x)(2x-3y)\\\\(9x^2)(2x-3y)[/tex]
Now distribute, multiply every term inside the parenthesis by the term outside of it
[tex](9x^2)(2x-3y)\\\\(9x^2)(2x) + (9x^2)(-3y)\\[/tex]
Simplify,
[tex]18x^3-27x^2y[/tex]
Therefore the solution is (d.) [tex]18x^3-27x^2y[/tex]

What is the rate of change of the linear function that has a graph that passes through (9,2) and (3,-1)?
Answers
=================================================
Explanation:
Your teacher wants you to find the slope
m = slope
m = (y2-y1)/(x2-x1)
m = (-1-2)/(3-9)
m = -3/(-6)
m = 1/2
----------------
Extra info:
We can think of the slope as
slope = rise/run
and furthermore,
rise = change in y = y2-y1run = change in x = x2-x1Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.

Ms. Masi is going to be paid $11.25 per day to look after Ms. Simms’ dog. She wants to save all of her earnings, but she owes her brother $72. After the first day of dogsitting, Ms. Masi uses her earnings to pay part of her debt to her brother. After the second day, she uses her earnings to pay more of her debt. Ms. Masi plans to save every dollar of her dog sitting money as soon as she has paid her brother in full.
How many days will it take for Ms. Masi to pay her brother in full? Explain.
Answers
Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 (d = # of days)
Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.
Hope this Helps! :)

books he checked out. How many books did Brian check out? *
Answers
Answer:
Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25
Total number of books borrowed= 16

Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answers
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.
[tex]\frac{1}{5} *\frac{5}{6} =\frac{5}{30} =\frac{1}{6}[/tex]

use the matrix tool to solve the system of equations enter the answer as an ordered pair. 8x+5y=9 -x+y=7
Answers
Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13
Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month. Use the drop-down menu below to write an inequality representing gg, the number of gigabytes she can use while staying within her budget.
Answers
Answer:
< 5 gigabytes
Step-by-step explanation:
Let the number of gigabytes be represented as: g
Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.
Under $60 = less than (<) $60
Hence, our inequality equation is given as:
$35 + $5 × g < 60
35 + 5g < 60
Collect like terms
5g < 60 - 35
5g < 25
g < 25/5
g < 5 gigabytes
Therefore, the number of gigabytes she can use while staying within her budget less than 5 gigabytes
Answer:
g<5
