Can someone help me please

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.

Answer:

The ball will land after 5.14s.

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:

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

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]

Answer:

Step-by-step explanation:

The answer is 570 because if you multiply 38 times 15 = 570 so it is 570. Thank you for answering to hope this helps you if you need more help contact me!

Answer:

$5.70

Step-by-step explanation:

Since it is 15% to make it a decimal you would move the decimal 2 places to the left to make it 0.15 and then multiply like this 38(.15) which is 5.7. So, shipping and handling is $5.70.

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]

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)

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:

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

Answer:

type of music listened to on the radio

Answer:

18 units

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:

[tex]x + 10\\8 + 10\\18[/tex]

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,

We need to solve it using identities.

>> (100 + 1)^2

As we know that,

>> (a + b)^2 = a^2 + b^2 + 2ab

Here,

Using the identity we gets,

>> (100)^2 + (1)^2 + 2(100)*(1)

>> 10000 + 1 + 200

>> 10000 + 201

>> 10201
