Answer:

The value of the equation for x is $x=\frac{64}{3}$ .

Step-by-step explanation:

Consider the provided equation.

$\frac{1}{2}+\frac{1}{4}=16$

We need to solve the equation for x.

Add the like terms as shown:

$\frac{2x+x}{4}=16$

$\frac{3x}{4}=16$

Multiply both the sides by 4/3.

$\frac{3x}{4}\times \frac{4}{3}=16\times \frac{4}{3}$

$x=\frac{64}{3}$

Hence, the value of the equation for x is $x=\frac{64}{3}$ .

What quadratic equation could be solved to find any solutions to the system of equations?

Kipish [7]

Answer:

Step-by-step explanation:

x²+7x-11=-5x+6

x²+7x+5x-11-6=0

x²+12x-17=0

$x=\frac{-12\pm \sqrt{12^2-4*1*(-17)} }{2*1} \\=\frac{-12 \pm \sqrt{144+68} }{2} \\=\frac{-12 \pm \sqrt{212}}{2} \\=\frac{-12+2\sqrt{53}}{2}\\=-6 \pm \sqrt{53}$

A whole number n which when divided by 4 gives 3 as remainder. What will be the remainder when 2n is divided by 4?.

jeyben [28]

When 2n is divided by 4 the remainder will be 2

Division is a simple operation in which a number is divided.

Given,

A whole number n which when divided by 4 gives 3 as remainder

We know,

Dividend = (Divisor × quotient)+ Remainder

Here,

Dividend = n

Quotient = 4

Remainder =3

Consider the divisor as a

Then,

n = 4a+3

Multiply both side by 2

2n= 2(4a+3)

2n= 8a+6

Split the term 6 and take common outside

2n= 8a+4+2

2n= 4(2a+1)+2

So, when 2n is divided by 4

Divisor = 2a+1

Remainder = 2

Hence, when 2n is divided by 4 the remainder will be 2

A problem contains the points (0,0),(1,-2) and (-1,-4). What is the equation of this parabola in standard form?

Bas_tet [7]

Answer:

The general equation of the parabola y = -3 x² + x

Step-by-step explanation:

Step(i):-

Given points are (0,0) , (1, -2) and ( -1 , -4 )

Given the standard parabola

y = ax²+ b x + c ...(i)

Passing through the point (0,0)

c = 0

Passing through the point (1,-2)

-2 = a(1) +b(1)

a + b = -2 ...(ii)

Passing through the point (-1, -4)

- 4 = a - b

a - b = -4 ...(iii)

Step(ii):-

Adding (ii) and (iii) equations , we get

2 a = -6

a = - 3

substitute a = - 3 in equation (ii)

-3 + b =-2

b = -2 + 3 = 1

Final answer:-

The general equation of the parabola

y = ax²+ b x + c

y = -3 x² + x + 0

y = -3 x² + x
