Solve for x and y x+y=32 x−y=8

Mathematics
1 answer:
slega [8]3 years ago
7 0

Answer:

x = 20 y= 12

Step-by-step explanation:

x+y=32

x−y=8

Add the two equations together to eliminate y

x+y=32

x−y=8

----------------

2x  = 40

Divide each side by 2

2x/2 = 40/2

x = 20

We know x so we can find y

x+y = 32

20+y = 32

20+y-20 = 32-20

y= 12

Use the product of powers property to simplify the expression –2x3y4x2y3.
Maslowich

Option d: -2x^{5} y^{7} is the correct answer.

Explanation:

The expression is -2x^{3} y^{4} x^{2} y^{3}

We need to simplify the expression, using the product of powers.

The product of powers states that "when multiplying two powers with the same base the exponent values can be added up".

Thus, grouping the same base and adding the exponent values from the expression -2x^{3} y^{4} x^{2} y^{3}, we have,

-2x^{3+2} y^{4+3}

Adding the exponent, we get,

-2x^{5} y^{7}

Thus, the simplified expression is -2x^{5} y^{7}

Hence, Option d is the correct answer.

What is the value of arcsin(0) in degrees?<br><br> Enter your answer in the box.
melisa1 [442]

Answer:

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.

Step-by-step explanation:

To Find:

arcsin(0) in degrees =?

Solution:

' arcsin ' a mathematical function that is the inverse of the sine function.

Therefore, arcsin (x) is called the inverse sine function.

It is the angle whose sine is the number x.

So here we require angle in degree for which the Sine is '0'.

It is also written as

\sin^{-1}x

We Know that

\sin 0\°=0\\or\\\sin 180\°=0

Therefore,

\arcsin (0) = 0\°\\or\\\arcsin (0) = 180\°

Also integer multiples of 180° will have

\arcsin (0)=n\times 180\°

Where n = integer

Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
