Y^2 isolate 19x^2+4y^2=25

Mathematics
1 answer:
qaws [65]4 years ago
6 0

Answer:

Simplifying

x2 + -4y2 = 25

Solving

x2 + -4y2 = 25

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y2' to each side of the equation.

x2 + -4y2 + 4y2 = 25 + 4y2

Combine like terms: -4y2 + 4y2 = 0

x2 + 0 = 25 + 4y2

x2 = 25 + 4y2

Simplifying

x2 = 25 + 4y2

Reorder the terms:

-25 + x2 + -4y2 = 25 + 4y2 + -25 + -4y2

Reorder the terms:

-25 + x2 + -4y2 = 25 + -25 + 4y2 + -4y2

Combine like terms: 25 + -25 = 0

-25 + x2 + -4y2 = 0 + 4y2 + -4y2

-25 + x2 + -4y2 = 4y2 + -4y2

Combine like terms: 4y2 + -4y2 = 0

-25 + x2 + -4y2 = 0

The solution to this equation could not be determined.

If you purchase a DVD player that cost $625 how much sales tax will you pay to the nearest cent if the rate is 7.375%
sergey [27]
We can get the tax pay by multiplying the total cost times the tax rate, and take into account that 7.375% = 7375/100000 that huge denominator comes from adding 100 more zeroes as the decimal places in the tax amount has, so we do have:
(7.375%)(625)
= (<span>7375/100000)(625)
= 46.09
therefore, the 7.375% out of $625 is $46.09</span>

PLEASE HELP! <br> Which of the following functions are the inverse of p(x)= √5x+7 ?
Rasek [7]

Answer: B

Step-by-step explanation:

You are given the function

p(x) = √5x+7

Let p(x) = y then,

Y = √5x+7

To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,

X = √5y+7

Square both sides

X^2 = 5y + 7

Make y the subject of formula

5y = x^2 - 7

Y = ( x^2 - 7 ) / 5

the correct answer is B
