Step-by-step explanation:

y - 4x = 3

Writing in slope intercept form that is y = mx + c

y = 4x + 3

Hope it will help :)

12 – 2x= -2(y – x)<br> -2x = -2(y – x) – 12<br> x= (y - x) + 6

Vilka [71]

Answer:

x=o and y= -6

Step-by-step explanation:

12-2x = - 2(y-x)

or,12-2x = -2y + 2x

or, 12 = - 2y + 4x

or, 12/2= 2x - y

or, 2x - y = 6

• 2x -6= y.....eqn_1

-2x=-2y+2x -12

or,4x +2y= -12

or,4x + 2(2x-6)= -12

or, 4x+4x-12=-12

or, 8x= 0

• x= o

putting the value of x in eqn...3

o=(y-0)+6

or, o= y + 6

•y = -6

Mr. Chan places $4000 in a bank as a fixed deposit for 2 years. The bank offers an interest compounded yearly. At the end of 2 y

serious [3.7K]

Answer:

Step-by-step explanation:

Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.

Each years the bank added a certain amount of interest.

At the end of the 2 years he gained 243 dollars and 60 cents just from interest.

How to solve:

Simply take away the 4 in the amount of money

Leaving: $243.60

( 2 years )

Now divide 243.60 by 1/2

which is 121.8

Mr.Chan got 121.8 worth of interest a year

$10.5 a month

$2.3 a week

6 cents a day

All in 2 years.

Solve the equation by using the quadratic formula.<br> 3 x squared minus 1 = 7 x

Paladinen [302]

Answer:

b. $\frac{7+\sqrt{61} }{6} ,\frac{7-\sqrt{61} }{6}$

Step-by-step explanation:

$3x^{2} -1=7x$

Quadratic equations are suppose to be written as: $ax^2+bx+c=0$

so the new quadratic equation for this problem will be: $3x^{2} -1-7x=0$

Now rearrange the terms: $3x^{2} -7x-1=0$

Then use the Quadratic Formula to Solve for the Quadratic Equation

Quadratic Formula = $x=\frac{-b±}{} \frac{\sqrt{b^2-4ac} }{2a}$

Note: Ignore the A in the quadratic formula

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

$3x^{2} -7x-1=0$

a = 3

b = -7

c = -1

$x=-(-7)±\frac{\sqrt{(-7)^2-4(3)(-1)} }{2(3)}$

Evaluate The Exponent

$x=\frac{7±\sqrt{(49)-4(3)(-1)} }{2(3)}$

Multiply The Numbers

$x=\frac{7±\sqrt{49+12} }{2(3)}$

Add The Numbers

$x=\frac{7±\sqrt{61} }{2(3)}$

Multiply The Numbers

$x=\frac{7±\sqrt{61} }{6}$
