If the product of x^2a-1/y^3b+4 and x^7b-4/y^10-a is x^24/y^19 find the value of a and b
lidiya [134]

Answer:

a = 4; b = 3

Step-by-step explanation:

For the question to make any sense, we need to add parentheses.

... x^(2a-1)/y^(3b+4) × x^(7b-4)/y^(10-a) = x^24/y^19

Equating exponents, we have ...

... (2a-1) + (7b-4) = 24 . . . . exponent of x in the product

... (3b+4) + (10 -a) = 19 . . . exponent of y in the product

Simplifying these two equations, we get

... 2a +7b = 29

... a -3b = -5

By Cramer's rule, ...

... a = (7·(-5) -(-3·29)/(7·1 -(-3·2)) = 52/13 = 4

... b = (29·1 -(-5·2))/13 = 39/13 = 3

_____

<em>More about Cramer's Rule</em>

If you have the linear equations ...

  • ax +by = c
  • dx +ey = f

The solutions for the variables x and y can be found directly from the equation coefficients as ...

... x = (bf -ec)/(bd -ea)

... y = (cd -fa)/(bd -ea) . . . . same denominator as for the first equation

Once you recognize the pattern in the products, the formula is not difficult to remember.

___

This is actually the Vedic math version of Cramer's rule. It differs from the usual presentation of Cramer's rule in that both numerator and denominator are negated. This makes the pattern of products easier to remember and gives exactly the same result.

EFGH is a rhombus. Given EG = 16 and FH = 12, what is the length of one side of the rhombus?
Tom [10]

<u>Answer</u>

= 10


<u>Explanation</u>

EG is one of the diagonals of the rhombus and the other diagonal is FH.

EG = 16 and FH = 12

The diagonals of a rhombus meet at 90°

From this information we can form a right triangle with legs (16/2)=8 and (12/2)=6

The hypotenuse of this triangle is the side of the rhombus.

Using the pythagorean theorem;

L² = 6²+8²

Where L is the length of the rhombus.

L² = 6²+8²

L = √36+64

= √100

= 10

Find the slope of the line represented by the table of values
Leya [2.2K]

Answer:

-5/3

Step-by-step explanation:

To solve for slope we use the slope formula which is y2-y1/x2-x1.

For this problem I chose the points: (-5,10) and (-2,5)

-5 is x1, 10 is y1, -2 is x2 and 5 is y2

We now plug in the points into the slope formula:

5-10/-2-(-5)= -5/3

April, Sean, Jessica, and Nathan are all going out to dinner using a $50 gift card from Nathan's mom. April's sandwich is $10.67
morpeh [17]

Answer: 18.83

Step-by-step explanation:

Alright here we go

50- 10.67 will equal 39.33

we use the same card for everyone so subtract their totals

39.33-11.42= 27.91

27.91-9.08= 18.83

Nathans steak dinner would cost 18.83

Hope this helped
