Simplify the following : x^2y^-3 / x^5y^2
Answer:
Step-by-step explanation:
[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}[/tex]
Remember that exponents (or powers) of the same basis can be divided by subtracting the exponents. For example [tex]\frac{x^n}{x^m} =x^{n-m}[/tex]
Using this information, we can easily rearrange our equation to look like this:
[tex]\frac{x^2}{x^5} \frac{y^{-3}}{y^2}[/tex]
Now that the basis are the same, we can conveniently subtract the exponents to get the following result:
[tex]x^{-3}y^{-5}[/tex] or [tex]\frac{1}{x^3y^5}[/tex]. And that's the final answer.

Given the system of equations:
2x + 2y = 12
X-y= 2
What is x equal to?
8
4
2
1
-2
Answer:
x=4
y=2
Step-by-step explanation:
2x+2y=12
x−y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+2y=12,x−y=2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+2y=12,2x+2(−1)y=2×2
Simplify.
2x+2y=12,2x−2y=4
Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.
2x−2x+2y+2y=12−4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
2y+2y=12−4
Add 2y to 2y.
4y=12−4
Add 12 to −4.
4y=8
Divide both sides by 4.
y=2
Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2=2
Add 2 to both sides of the equation.
x=4
The system is now solved.
x=4,y=2
Correct choice is B) x=4.
answer is 4
because y=2 then you subsistute it in and then you find X
x-y=2 turns to x=y+2 then you subsistute that into x of the equation 2x+2y=12 which then is 2(y+2)+2y =12 and you should get y=2 then you grab the other equation x-2=2 and you should get x=4
(101)² solve it using identities
Answer:
10201
Step-by-step explanation:
=(101)²
=(100+1)²
={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]
=10000+200+1
=10201
Solution :-
Given,
(101)^2We need to solve it using identities.
>> (100 + 1)^2
As we know that,
>> (a + b)^2 = a^2 + b^2 + 2ab
Here,
a = 100 b = 1Using the identity we gets,
>> (100)^2 + (1)^2 + 2(100)*(1)
>> 10000 + 1 + 200
>> 10000 + 201
>> 10201

Answer:
Option A
37°
Step-by-step explanation:
4x+ 2 = 150° [Vertically Opposite Angles]
=> 4x = 150 - 2
=> 4x = 148
[tex] = > x = \frac{148}{4} [/tex]
=> x = 37° (Ans)
Answer:
(4x+2)°=150°[by vertical opposite angles]
4x=150-2
4x=148
x=148/4
x=37
triangle ABC is similar to triangle EHG , find the measure of angle EHG .
Answer:
[tex]\angle EHG = 80[/tex]
Step-by-step explanation:
Given
ABC ∼ EHG
See attachment
Required
Determine [tex]\angle EHG[/tex]
First, we calculate x in ABC
[tex]x + 2x + 60= 180[/tex]
[tex]3x + 60= 180[/tex]
[tex]3x = 120[/tex]
[tex]x = 40[/tex]
The corresponding angle to [tex]\angle EHG[/tex] is [tex]\angle ABC[/tex]
and
[tex]\angle ABC = 2x[/tex]
[tex]\angle ABC = 2 * 40[/tex]
[tex]\angle ABC = 80[/tex]
Hence:
[tex]\angle EHG = 80[/tex]
Kevin is doing an experiment where he flips a fair coin 20 times and analyzes the results. The coin has come up heads the first 19 trials. What is the conditional probability that the next flip will come up tails, given that the previous 19 flips were heads? Explain why your answer makes sense.
Answer:
it's still 50%
each flip is an independent probability. what happened the first 19 times is irrelevant, because it's still a 50-50 chance on any independent flip.

y=6x-11
-2x-3y=-7
find the solution plz
if you solve using subsitution, the point form would be (2,1) and the equation form = 2, y=1
Answer:
x = -2
y = -23
(x, y) --> ( -2, -23)
Step-by-step explanation:
y = 6x - 11
-2x - 3y = -7
***What you need to do is substitute the "y" with what has been given to us which is "6x - 11"***
-2x - 3(6x - 11) = -7
Now what you need to do, is use the distributive property (multiply what is in the parenthesis "6x - 11" by what is outside of it "3").
-3 × 6x and -3 × -11
-18x and 33
Now we have......
-2x - 18x + 33 = -7
Now we can combine like terms (put the numbers that are the same together - variables with variables, and whole numbers with whole numbers)
-2x - 18x = -20x (2 negatives added together gives u a result of a bigger negative number)
-20x + 33 = -7
Now we need to subtract 33 on both sides
-20x + 33 - 33 = -7 - 33
-20x = -40
Now we need to divide by -20 on both sides to isolate the variable
-20x ÷ -20 = -40 ÷ 20
x = -2
Now that we have what "x" is, we can use that to find what "y" is....
y = 6x - 11
Substitute the "x" with the answer we got "-2".
y = 6(-2) - 11
y = -12 - 11
y = -23
x = -2
y = -23
Now we can check our work
y = 6x - 11
All we need to do is substitute the "x" and "y" with the answer we got above.
y = 6x - 11
-23 = 6(-2) - 11
-23 = -12 - 11
-23 = -23
CORRECT
So now that we checked our work, and saw that it was correct, I can hereby say that x is -2 and y is -23
x = -2
y = -23
(x, y) --> ( -2, -23)
Hope this helped!!!

Answer:
a) OP:RT = 10:3
b) OQ = 15 cm
c) m<P = [tex]60^{o}[/tex]
d) m<Q = [tex]94^{o}[/tex]
Step-by-step explanation:
Given that: ΔOPQ is similar to ΔRTS
Then;
a) OP:RT = 12:3.6
= [tex]\frac{120}{36}[/tex]
= [tex]\frac{10}{3}[/tex]
= 10:3
The ratio of OP to RT is 10:3.
b) The measure of length OQ = [tex]\frac{10}{3}[/tex] x 4.5
= 15 cm
c) m<P ≅ m<T
So that,
m<P = [tex]60^{o}[/tex]
d) m<Q ≅ m<S
But,
26 + 60 + m<S = 180 (sum of angles in a triangle)
86 + m<S = 180
m<S = 180 - (86)
= [tex]94^{o}[/tex]
Thus,
m<Q = [tex]94^{o}[/tex]
PLS HELP ME FAST FREE 16 POINTS Rectangle PQRS is graphed on a coordinate plane with vertices P(–2, 1), Q(–2, 4), R(–4, 4), and S(–4, 1), as shown below.
Rectangle PQRS is reflected over the y–axis and then translated 2 units to the left. What are the coordinates of P'?
O(1, 0)
O(0, 1)
O(4, 1)
O(–4, –1)
Answer:
Pretty sure it's B!
Step-by-step explanation:
Over the Y axis- (2,1)
To the left two times= (0,1)
Hope this helped!
Answer:
(0,1)
Step-by-step explanation:
Since the problem is only asking about P', let's ignore the rest of the rectangle. P's coordinates are to be reflected across the y-axis, putting P' at (2,1). Move P' left by two units and your 'x' is 0, your 'y' is the same. So, (0,1)

Step-by-step explanation:
A picture of what it would look like is at the bottom.
You know that the legs are equal because it's isosceles, so AB = AC. This means:
[tex]4x - 14 = x + 10\\3x - 14 = 10\\3x = 24\\x = 8[/tex]
using the rules of solving an equation.
The length of one leg is:

1. Rafael stands 55 feet from the tower and uses a clinometer to measure the angle of elevation to the
viewing platform as 37º. How far up the tower is the viewing platform?
Answer:
41.4feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Given the following
Distance of Rafael from the tower = 55feet = Adjacent
Angle of elevation = 37degrees
Required
Height of the tower = Opposite
Since Tan theta = opp/adj
Tan 37 = x/55
x = 55tan37
x = 55(0.7536)
x = 41.4
Hence the tower is 41.4feet up the viewing platform

Answer:
The slope is -3.75 or -15/4.
Step-by-step explanation:
The formula for slope is the change in y over the change in x.
To do this, you subtract 7-3 to get you 4 on the bottom of the fraction and -7-8 which is -15.
So pretty much, you get -15/4. :)
