Step-by-step explanation:
(3x-2/x)^10
(r+1)th term = 10Cr (3x)^10-r (-2/x)^r
= 10Cr (3)^10-r (-2)^r (x)^10-2r
Let 10-2r = 12
- 2r = 2
r= - 1
The coefficient of x^12
= 10C-1 (3)^11 (-2)^-1
= 10C11 (3)^12 (-1/2)
= (1/11) (3)^12 (-1/2)
= - 1/22 × (3)^12

What is the area, in square meters, of the shape below? Express your answer as a fraction in simplest form.
Step-by-step explanation:
A = 1/2 × at
a = 5/3 meter
t = 1/2 meter
A = 1/2 × 5/3 × 1/2
A = (1 × 5 × 1)/(2 × 3 × 2)
A = 5/12 m²
Write an equation for a line parallel to 4x – 2y = 4 that passes through the point (3,22)
Answer:
y = 2x + 16
Step-by-step explanation:
4x - 2y = 4
-2y = -4x + 4
y = -4/-2x + 4/-2
y = 2x - 2
Slope: 2
Point: (3,22)
y-intercept: 22 - (2)(3) = 22 - 6 = 16
Answer:
y=2x+16 or 2x-y=-16
Step-by-step explanation:
Hi there!
We are given the equation 4x-2y=4, and we want to write an equation for the line parallel to it, that also passes through (3, 22)
First, let's find the slope of the line, as parallel lines have the same slope.
In order to find the slope, we can convert the equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).
Start by subtracting 4x from both sides:
-2y=-4x+4
Divide both sides by -2
y=2x-2
2 is in the place where x is, so the slope of the line is 2
It's also the slope of the line parallel to it.
Writing the equation in slope-intercept form, this is the equation so far:
y=2x+b
Now let's find b
Since the equation passes through the point (3,22), we can use it to help solve for b
Substitute 22 as y and 3 as x:
22=2(3)+b
Multiply
22=6+b
Subtract 6 from both sides
16=b
Substitute 16 as b in the equation.
y=2x+16
We can stop right here, but we can also re-convert it into standard form
To do that, subtract 2x from both sides:
-2x+y=16
There's a rule that the coefficient in front of x CANNOT be negative; in order to change the sign, multiply both sides of the equation by -1
2x-y=-16
Hope this helps!

what is 2x+3=r+2 ???
Answer:
R.4
thank you good luck
Answer:
What variable are you trying to solve? Imma just guess you are trying to solve for x since its on the left side so...
2x+3=r+2
Subtract three from both sides
2x=r-1
Divide 2 from both sides
x=r-1/2 OR
x=1/2r+-1/2

Answer:
Green line
Step-by-step explanation:
This is the only line that has coordinates (1,2) and the slope is positive.
Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.
Step-by-step explanation: hope this helps.

The artist R. Locklen Jones selects 3 paintings from a collection of 6 to display in a row. How many different arrangements of the display are possible
Using the combination formula, it is found that 20 different arrangements of the display are possible.
The order in which the paintings are displayed is not important, hence, the combination formula is used to solve this question.
Combination formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, 3 paintings are chosen from a set of 6, hence:
[tex]C_{6,3} = \frac{6!}{3!3!} = 20[/tex]
20 different arrangements of the display are possible.

If the price of a yo-yo in a shop increased by 20% and is now $3.60, what was the original price?
Answer:
$3.00
Step-by-step explanation:
$3.00 x .2 = 0.60. added to original
The original price of the yo-yo in a shop is $3.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
It is given that the price of a yo-yo in a shop increased by 20% and is now $3.60.
The original price will be calculated as let the original price is x dollars. Then from the question, the expression will be formed as below:-
1.20x = 3.60
x = 3.60 / 1.20
Divide 3.60 by 1.20 to get the value of x.
x = $3
It means that the 20 percent is equal to the amount of $0.6.
Therefore, the original price of the yo-yo in a shop is $3.

Answer:
.39
Step-by-step explanation:
just did the math
Correct Answer is 0.13
Probability:
The probability formula is the number of favourable outcomes to the total number of all the possible outcomes.
The probability of an Event = (Number of favourable outcomes) / (Total number of possible outcomes)
P(A) = n(E) / n(S)
Here, (Given)
n(E) = The participant prefers football and the event is foam finger = 39
n(S) = Total number of outcomes = 300
P(A) = probability the participant prefers football and the event foam finger.
P(A) = 39 / 300
P(A) = 0.13
