what is x -2(4x-3)=-12-14x

Answer:

first try taking the common

Step-by-step explanation:

x(3x+2)=0

3x=-2

x=-2/3

Answer:

x = - [tex]\frac{2}{3}[/tex] , x = 0

Step-by-step explanation:

Given

3x² + 2x = 0 ← factor out x from each term

x(3x + 2) = 0

Equate each factor to zero and solve for x

x = 0

3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]

Answer:

(a) 60.45 m2.

(b) 332.475 m^3.

Step-by-step explanation:

(a) area =  length * width

= 9750 * 6200

= 60450000 mm^2

There are 1000*1000 = 1,000,000 mm^2 in 1 m^2 so the area in m^2

= 60.45 m^2.

(b) The height in meters is 5500 / 1000 = 5.5 m

Volume = area of floor * height

= 60.45 * 5.5

= 332.475 m^3.

Answer:

[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]

Step-by-step explanation:

Given

[tex]Dividend = 125x^3 - 8[/tex]

[tex]Divisor = 5x - 2[/tex]

Required

Determine the quotient

See attachment for complete process.

First, divide 125x^3 by 5x

[tex]\frac{125x^3}{5x} =25x^2[/tex]

Write [tex]25x^2[/tex] at the top

Multiply [tex]5x - 2[/tex] by [tex]25x^2[/tex]

[tex]= 125x^3 - 50x^2[/tex]

Subtract from 125x^3 - 8

i.e.

[tex]125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8[/tex]

Step 2:

Divide 50x^2 by 5x

[tex]\frac{50x^2}{5x} = 10x[/tex]

Write [tex]10x[/tex] at the top

Multiply [tex]5x - 2[/tex] by [tex]10x[/tex]

[tex]= 50x^2 - 20x[/tex]

Subtract from 50x^2 - 8

i.e.

[tex]50x^2 - 8 - (50x^2 - 20x) = 20x - 8[/tex]

Step 3:

Divide 20x by 5x

[tex]\frac{20x}{5x} = 4[/tex]

Write [tex]4[/tex] at the top

Multiply [tex]5x - 2[/tex] by [tex]4[/tex]

[tex]= 20x - 8[/tex]

Subtract from 20x - 8

i.e.

[tex]20x - 8 - (20x - 8) = 0[/tex]

Hence:

[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]

☁️ Answer ☁️

10, x = 10

x/5=2

simplify the equation to the form

x/5=2

Simplifying:

+ 0.2x=2

move all terms containing x to the left and all other terms to the right.

+ 0.2x=+2

simplify left and right side of the equation.

+ 0.2x=+2

divide both sides of the equation by 0.2 to get x.

x=10

the correlation coefficient for Alfonso survey is 0.36.

The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.

For the given situation,

The table below shows the values of the data x, y and the correlation calculations.

The formula of correlation coefficient is

[tex]r=\frac{n(\Σ xy)-(\Σ x)(\Σ y)}{\sqrt{[n\Σ x^{2} -(\Σ x)^{2} }] [n\Σ y^{2}-(\Σ y)^{2} ]}[/tex]

From the table substitute all the values.

⇒ [tex]r=\frac{(11)(98-(37)(26))}{\sqrt{[11(153)-37^{2} ][(11)(92)-26^{2} ] }}[/tex]

⇒ [tex]r=\frac{1078-962}{\sqrt{(1683-1369)(1012-676)} }[/tex]

⇒ [tex]r=\frac{116}{\sqrt{(314)(336)} }[/tex]

⇒ [tex]r=\frac{116}{324.81}[/tex]

⇒ [tex]r=0.357[/tex] ≈ [tex]0.36[/tex]

Hence we can conclude that the correlation coefficient for Alfonso survey is 0.36.

Answer:

Center- (-13, -6)

Radius = 12 units

Step-by-step explanation:

The radius is gotten by first taking the distance between the point using the distance formula

D = √(-11+1)²+(-25+1)²

D = √(-10)²+(-24)²

D = √100 + 576

D = √676

D = 26

This gives the diameter of the circle

Radius = diameter/2

radius = 26/2

Radius = 12

The center of the circle is the midpoint of the coordinate

X = x1+x2/2 and Y = y1+y2/2

X = -1 - 25/2

X = -26/2

X = -13

Y = -1 - 11/2

Y = -12/2

Y  = -6

Hence the center is at (-13, -6)

4. 4

Step-by-step explanation:

3 . so  [tex]h^{2} = g^{?+3} h^{2}[/tex], we cancel the [tex]h^{2}[/tex] out and it leaves us with [tex]1=g^{?+3}[/tex]

Which means ?+3=0, and ?=-3

4. so [tex]k^{?} = k^{4}[/tex], ?=4

Answer:

x=3

Step-by-step explanation:

To solve for x, get x alone on one side of the equation.

First, add 3 to both sides.

3 = 1/3x^2

Multiply each side by 3

x^2 = 9

Take the square root of both sides

x = + or - 3

You want the positive solution, so x = 3

Answer:

The equation is;

4y = 7x + 2

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

m = (y2-y1)/(x2-x1)

(x1,y1) = (2,3)

(x2,y2) = (-2,-4)

m = (-4-3)/(-2-2) = -7/-4 = 7/4

So we have the equation as;

y = 7x/4 + b

To

get the value of b, we will substitute any of the points (let us use 2,3)

We simply substitute 2 for x and 3 for y

We have this as:

3= 7(2)/4 + b

3 = 7/2 + b

b = 3-7/2 = -1/2

So we have the equation as;

y = 7x/4 + 1/2

multiply through by 4

4y = 7x + 2

Step-by-step explanation:

Given that the sum of arithmetic sequence =

n/2[2a + (n-1)d]

Where;

n = 575

a = -4910

d = a i - a i-1  = 8

Substituting values;

575/2 [2(-4910) + (575 -1) 8]

575/2  [(-9820) + 4592]

=  - 1,503,050

Given:

Rate of simple interest = 5%

Time = 4 years

Total interest = $160

To find:

The amount borrowed by Austin from a credit union.

Solution:

The formula for simple interest is:

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Where, P is principal, r is the rate of interest and t is the number of years.

Putting [tex]I=160,r=5,t=4[/tex] in the above formula, we get

[tex]160=\dfrac{P\times 5\times 4}{100}[/tex]

[tex]160=\dfrac{20P}{100}[/tex]

[tex]160=\dfrac{P}{5}[/tex]

Multiply both sides by 5.

[tex]800=P[/tex]

Therefore, Austin borrowed $800 from a credit union for 4 years.
