Y - 3x = 4

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
5 0

Answer:

y = 3x+4

y = -2x-1  

Step-by-step explanation:

slope intercept form

y= mx+b  where m is the slope and b is the y intercept

to get in this form we solve for y


y -3x =4

add 3x to each side

y-3x+3x = 3x+4

y = 3x+4   where 3 is the slope and 4 is the y intercept


2x+1 = -y

flip the sides

-y = 2x+1

multiply  by -1

-1* -y = -1 * 2x + -1 *1

y = -2x-1    the slope is -2 and the y intercept is -1

Find the amount to be paid at the end of 3years in each case. a) principal =1,200 at12% p.a​
Viktor [21]

Answer:

$1632

Step-by-step explanation:

Given data

Principal= $1200

Rate= 12%

Time= 3 years

The simple interest expression is given as

A= P(1+rt)

substitute

A=1200(1+0.12*3)

A=1200(1+0.36)

A=1200*1.36

A=$1632

Hence the amount is $1632

Why is it mathematically legal to multiply 2 √ 2 by √ 2 √ 2 in order to rationalize the denominator?
Gala2k [10]
Well if you're referring to rationalizing \bf \cfrac{2}{\sqrt{2}}, which simply means, getting rid of the pesky radical at the bottom

well, it boils down to, hmm say... a quantity or even a polynomial, multiplied times 1, is itself, 2*1=2, 3*1 = 3, ducks*1 = ducks, spaghetti * 1 = spaghetti

or whatever * 1 = whatever
and the value of the multiplicand, doesn't change in anyway, is the same thing before and after the multiplication by 1

now....1 can also be a fraction  \bf \cfrac{2}{2}=1\qquad \cfrac{3}{3}=1\qquad \cfrac{1,000,000}{1,000,000}=1&#10;\\\\\\&#10;\cfrac{ducks}{ducks}=1\qquad \cfrac{spaghetti}{spaghetti}=1\qquad \cfrac{cheese}{cheese}=1&#10;\\\\\\&#10;\cfrac{\textit{the quick fox jumped}}{\textit{the quick fox jumped}}=1\qquad \cfrac{whatever}{whatever}=1

so.. when you're doing \bf \cfrac{2}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\iff \cfrac{2}{\sqrt{2}}\cdot1

and the value multiplicand doesn't change in any way

now, try this in your calculator  \bf \cfrac{2}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\implies \cfrac{2\sqrt{2}}{\sqrt{2^2}}\implies \cfrac{2\sqrt{2}}{2}\implies \sqrt{2}\\\\&#10;-----------------------------\\\\&#10;\textit{check how much is }\cfrac{2}{\sqrt{2}}\textit{ in your calculator}&#10;\\\\\\&#10;\textit{then check how much is }\sqrt{2}\textit{ in it}
