The simplest form in parenthesis is option C which is negative five sixths times x plus eight  (- 5x/6 + 8)

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

WE have Given equation as; parenthesis negative two thirds times x minus 6 end quantity minus quantity negative 14 plus one sixth times x end parenthesis,

( -2/3 * x - 6 )  -  ( -14 + 1/6 * x)

Now solving the equation will gives;

= ( -2/3 * x - 6 ) - ( -14 + 1/6 * x )

= ( -2x/3 - 6 ) - ( -14 + x/6 )

= -2x/3 - 6 + 14 - x/6

Now collecting like terms;

= -2x/3 - x/6 - 6 + 14

= - 5x/6 + 8

Therefore the correct answer is option C; negative five sixths times x plus eight (- 5x/6 + 8)

If the function of height in time is h(t)=-4.9[tex]t^{2}[/tex]+106t+206,then the rocket will splash down into the ocean after 23.43 seconds and the rocket will get its peak after 10.82 seconds at a height of 779.26524 meters above the sea level.

Given that the function of height in time is h(t)=-4.9[tex]t^{2}[/tex]+106t+206.

We are required to find the time after which the rocket will splash down into the ocean and the time after which the ocean will get its peak and the height of the rocket.

The rocket will splash down when the height of the rocket is 0.

-4.9[tex]t^{2}[/tex]+106t+206=0

4.9[tex]t^{2}[/tex]-106t-206=0

t={106±[tex]\sqrt{(106)^{2} -4*4.9*(-206)}[/tex]}/2*4.9

t=(106±[tex]\sqrt{15273.6}[/tex])/9.8

We have to ignore the negative sign because the time is always shown in positive signs.

t=(106+123.59)/9.8

t=229.59/9.8

t=23.43 seconds

Rocket will be at its peak when the slope of the equation is 0.

[tex]h^{I}[/tex](t)=-9.8t+106

-9.8t+106=0

-9.8t=-106

t=-106/-9.8

t=10.82 seconds

To find the height we need to use t=10.82 in the equation.

h(10.82)=[tex]-4.9*(10.82)^{2} +106*10.82+206[/tex]

=-573.65476+1353.92

=779.26524 meters.

Hence if the function of height in time is h(t)=-4.9[tex]t^{2}[/tex]+106t+206,then the rocket will splash down into the ocean after 23.43 seconds and the rocket will get its peak after 10.82 seconds at a height of 779.26524 meters above the sea level.

Point K coordinate from the given number line is; -1²/₃

Partitioning of a line segment means dividing the line segment in the given ratio. The two numbers in the ratio must add up together to equal the total number of partitions of the line segment. For example: If a line segment AB is divided into a ratio of 2:3, it shows that the line segment can be divided into 5 equal sections. Hence, there are 5 parts in total, in which 2 parts will be before the desired point and 3 parts will be after the desired point.

We are given a line segment A F divided into different parts of points B, C, D and E.

Now, we want to find the point K such that it divides Line segment A F in the ratio 4:5.

Now, from the number line, line A F measures 12 units. Thus;

Point K = (4/5) * 12 = 5¹/₃ from point A

Thus, point K coordinate = -7 + 5¹/₃

Point K coordinate = -1²/₃

The required value of HE is 55 units.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal.

Now it is given that Points​ E, D, and H are the midpoints of the sides of ΔTUV.

UV = 110​,

TV = 140​, and

HD = 110

Since the triangles are similar there exists correspondance in the angles, so in order to solve this you just have to clear the function:

HD/HE = TV/(TV/2)

Put the values we get,

110/HE = 140 / 70

⇒ HE = 110*70/140

⇒ HE = 55 units

Answer:

174

Step-by-step explanation:

Since we don't know how many toys Carly has, we'll use a variable (x). The equation would then be:

x+3x=232

We can then combine like terms, and the new equation would be:

4x=232

Now, we have to get x by itself. To do this, divide both sides by 4, and you get:

x=58

But, remember, x is how many Carly has. Amy has three times that, so:

58*3=174

Amy has 174 toys.

Hope this helps!

Check the picture below.

there were total 201 republicans and 232 democrats .

There is only one or two variables in a linear equation. Nothing can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All the dots fall on the same line when the values that, when added together, make a linear equation true are determined and plotted on a coordinate grid.

let no. of republicans be x

then, no. of democrats is x + 30

total no. of  members given are = 433

  so if we make the equation

           x + x + 30 = 433

          2x = 403

            x = 201 members of republican

        democrats = 201 + 30 = 232

A(x) = $25 + $0.09*x

And plan B just charges $0.11 for each minute, then here we have the linear equation:

B(x) = $0.11*x

The costs are the same when:

A(x) = B(x)

$25 + $0.09*x = $0.11*x

Now we can solve this for x.

$25 = $0.11*x - $0.09*x = $0.02*x
