What is the greatest common factor of 28x²y-7xy^5?

7xy would be the greatest common factor. You can divide both terms by 7xy. 7 goes into 28 4 times ad you can factor out both an x and a y from both terms. You would end up with: 7xy(4x-y^4).

The greatest common factor of this can be solved by looking at the individual parts and splitting it up.

First, we have 28 and 7. Well, thats an easy one. 7 goes into 28 4 times so we are now left with 4 and 1.

We can also write the rest of this like this 4(x*x*y) - 1(x*y*y*y*y*y)

Now, what values are in both equations. We have one x and one y that can be taken out of both.

We end up with 7xy(4x-7y^4)

What is the value of b in the equation (y)*

KonstantinChe [14]

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that $\frac{1}{x^{n}} = x^{-n}$

In this case, $\frac{1}{y^{24}} = y^{-24}$

Set that equal to $(y^{b})^{4}$ :

$(y^{b})^{4} = y^{-24}$

Apply the exponent rule that $(x^{m})^{n} = x^{mn}$ so now you get:

$y^{4b} = y^{-24}$

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6

To get the x and the y

Roman55 [17]

Answer:

x = 16

y = 20

Step-by-step explanation:

the left part of the triangle can be solved first as it already has one angle and 1 side, we use trigonometry for this.

since we have 2 sides and 1 angle, to find the third side length we use the pythagoras theorem. a² + b² = c²

; 9² + 12² = c²

; 225 = c²

;√225 = c

; 15 = c

since we have all the lengths of the triangle, we can find out the angle opposite to the side length '9',

; $\frac{Sin x}{9} = \frac{sin90}{15}$

; $\frac{Sin 90}{15}$ x 9 = Sinx

36.86 = x

now, we look at the triangle as a whole, the top angle being 90 degrees, we know that we have 36.86.

; 90 - 36.86 = 53.13

$\frac{y}{Sin 90} = \frac{12}{Sin 36.86}$

; $\frac{12}{sin 36.86}$ x Sin 90 = 20

y = 20

again, since we have 2 sides of a right angled triangle we use a² + b² = c²

we arrange this formula since we have the hypotenuse

; 20² - 12² = 256

; √256 = x

; 16 = x

Option D: 140° is the right answer

Step-by-step explanation:

In the given figure, a traversal is intersecting two parallel lines.

When two parallel lines are intersected by a traversal 8 angles are formed.

Corresponding angles:

Corresponding angles have same relative position when two parallel lines are intersected by a traversal So in the given figure the corresponding angles are:

m∠1 and m∠5

m∠2 and m∠6

When two parallel lines are intersected by a traversal, the corresponding angles are equal

So,

m∠1 = m∠5

m∠5 = 140°

Hence,

Option D: 140° is the right answer
