How do i solve this equation 5x-3y=12 for y

I am Lyosha [343]

We have such equation
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y= $\frac{-5x+12}{3}$ /*(-1) multiply both sides by -1
y=- $\frac{-5x+12}{3}$
y= $\frac{5x-12}{3}$ - its the answer

Answer:

$86.81

Step-by-step explanation:

Using the given formula, we want to compute A for ...

P = 4750

r = 0.2279

n = 365 . . . . . assuming "exact" interest

t = 1 or 30

For 1 day late:

A = 4750(1 +0.2279/365)^(365·(1/365)) = 4752.97

For 30 days late:

A = 4750(1 +0.2279/365)^(365·(30/365)) = 4839.78

The difference in these payment amounts is ...

$4839.78 -4752.97 = $86.81

You would save $86.81 in interest charges by paying only 1 day late.

<em>Comment on the question</em>

It would be a poor choice of credit card to use one that compounds interest daily. Most do so on a monthly basis.

If a=2b^3 and b= -1/2c ^-2,express a in terms of c.

Answer:

Part 1) $a=-\frac{1}{4c^6}$

Part 2) $a=-\frac{1}{4c^{-6}}$

Step-by-step explanation:

Part 1) we have

$a=2b^{3}$ ----> equation A

$b=-\frac{1}{2}c^{-2}$ ----> equation B

substitute equation B in equation A

$a=2(-\frac{1}{2}c^{-2})^{3}$

Applying property of exponents

$(x^{m})^{n}=x^{m*n}$

$x^{-m} =\frac{1}{x^{m}}$

$a=2(-\frac{1}{2}c^{-2})^{3}=2(-\frac{1}{2})^3(c^{-2})^{3}=2(-\frac{1}{8})(c^{-6})=-\frac{1}{4c^6}$

therefore

$a=-\frac{1}{4c^6}$

Part 2) we have

$a=2b^{3}$ ----> equation A

$b=-\frac{1}{2c^{-2}}=-\frac{c^{2}}{2}$ ----> equation B

substitute equation B in equation A

$a=2(-\frac{c^{2}}{2})^{3}$

Applying property of exponents

$(x^{m})^{n}=x^{m*n}$

$x^{-m} =\frac{1}{x^{m}}$

$a=2(-\frac{c^{2}}{2})^{3}=2(-\frac{c^{6}}{8})$

simplify

$a=-\frac{c^{6}}{4}$

therefore

$a=-\frac{1}{4c^{-6}}$
