Four times the sum of half a number and 6 is 48. How do you put this in an equation? Please help.

Answer:

Step-by-step explanation:

The center of dilation is at the point of intersection of the lines through an image point and the corresponding pre-image point.

Here, A and A' are both on the line x=5. C and C' are both on the line y=2, so the center of dilation is (x, y) = (5, 2).

__

The point A' is half as far from (5, 2) as the point A is, so the scale factor of the dilation is 1/2. (A' is 3 units down; A is 6 units down from the center of dilation.)

Answer:

x = 17

Step-by-step explanation:

To solve this equation, we can illustrate the algebraic concepts being employed and solve for the variable.

3(x - 4) = 2x + 5 Distribute the 3 into the parentheses.

3x - 12 = 2x + 5 Subtract 2x from both sides of the equation to combine like terms.

x - 12 = 5 Add 12 to both sides of the equation.

x = 17

Answer:

[tex] \displaystyle \rm \longmapsto \:3(x - 4) = 2x + 5[/tex]

[tex] \displaystyle \rm \longmapsto \:3x - 12 = 2x + 5[/tex]

[tex] \displaystyle \rm \longmapsto 3x - 2x - 12 = 2x - 2x + 5[/tex]

[tex]\displaystyle \rm \longmapsto x - 12 = 5[/tex]

[tex]\displaystyle \rm \longmapsto x - 12 + 12 = 5 + 12[/tex]

[tex]\displaystyle \rm \longmapsto x = 15[/tex]

Please let me know if you have any question

Answer:

No, but (13,52) is

Step-by-step explanation:

To find this you need to understand what (13,51) means.

13 = x coordinate

51 = y coordinate

If you plug 13 into the equation given (P = 4s) you get 52. Therefore, (13,51) is not a solution but instead (13,52) is.

This means each of the four sides has a length of 13 units.

I hope this helps!

Answer:

P = 52

Step-by-step explanation:

51 = 13(4)     13x4=52

51 does not equal 52 there fore those values are immensely incorrect.  However you may state  52 as the perimeter therefore allowing 52 1to equal 13(4).

New solution 52 =13(4)

Answer:

Interest earned in two years is approximately $1,837

Step-by-step explanation:

A= P( 1+r/n)^nt

Where,

A= principal + interest

P= principal= $10,000

r= interest rate = 8.5%

t= Time = 2years

n = periods = 4

A= P( 1+r/n)^nt

= 10,000(1+0.085/4)^4*2

= 10,000( 1 + 0.0213)^8

= 10,000(1.0213)^8

= 10,000(1.1837)

=11,837

A= $11,837

The interest earned in two years is

A = p + I

A - P = I

$11,837 - $10,000 = I

$1,837 = I

I= $1,837

Interest earned in two years is approximately $1,837

Answer: v = 793.77 mph

Step-by-step explanation: Linear speed of a circular movement is calculated by using the formula:

v = ω.r

where

ω is angular velocity

r is radius of the path

Angular velocity is the rate of change of the angular position of an object with respect of time, i.e., is how fast an object changes its angular position with time:

[tex]\omega = \frac{d \theta}{dt}[/tex]

[tex]\omega = \frac{2\pi}{time}[/tex]

The Earth takes 24 hours to complete a rotation, then angular velocity:

[tex]\omega = \frac{2\pi}{24}[/tex]

[tex]\omega =[/tex] 0.262 rad/h

At a location 40° north, radius is 3033.5 miles, so:

v = 0.262*3033.5

v = 793.77

At latitude of 40°north, linear speed is 793.77mph.

Answer:

10

Step-by-step explanation:

Since T is the midpoint of PQ, we know that PT = TQ, therefore:

3x + 1 = 5x - 5

-2x = -6

x = 3

Since PT = 3x + 1, the answer is PT = 3 * 3 + 1 = 10.

Answer:

The answer should be:

[tex]=\frac{8x^3-18x}{3x+2}[/tex]

The closest answer is A, so I'll go with that.

Step-by-step explanation:

So we have the rational expression:

[tex]\frac{4x^3-9x}{2x-7}\div\frac{3x^2+2x^2}{4x^2-14x}[/tex]

First, remove the division sign. To do so, turn the division into multiplication and flip the second term:

[tex]\frac{4x^3-9x}{2x-7}\cdot \frac{4x^2-14x}{3x^2+2x}[/tex]

Now, simplify. From the first term, in the numerator, factor out a x. On the second term, factor out a 2x in the numerator and a x in the denominator:

[tex]\frac{x(4x^2-9)}{2x-7}\cdot\frac{2x(2x-7)}{x(3x+2)}[/tex]

Multiply straight across:

[tex]\frac{x(4x^2-9)(2x)(2x-7)}{(2x-7)(x)(3x+2)}[/tex]

Cancel out the (2x-7):

[tex]\frac{x(4x^2-9)(2x)}{x(3x+2)}[/tex]

Cancel out the x:

[tex]\frac{(2x)(4x^2-9)}{(3x+2)}[/tex]

At this point, we can factor the (4x^2-9) term, but we won't be able to cancel it out. Thus, this is the simplest it can get.

To get the answer, expand the numerator:

[tex]=\frac{8x^3-18x}{3x+2}[/tex]

Thus, the answer is...

A?

Answer:

The right solution is option a : [tex]\frac{8x^2 - 18}{3x+2}[/tex]

Step-by-step explanation:

We have to simplify the following rational expression,

[tex]\frac{4x^3-9x}{2x-7}[/tex] ÷ [tex]\frac{3x^3+2x^2}{4x^2-14x}[/tex]

Take into account the rule (a / b) / (c / d) = ad / bc. This simplifies the expression a bit further --- (1)

[tex]\left(4x^3-9x\right)\left(4x^2-14x\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]

Let's now factor each individual expression as demonstrated below. Afterwards we can substitute back into the expression above --- (2)

Goal - Factor : (4x³ - 9x)(4x² - 14x),

4x³ - 9x ⇒ x(4x² - 9)

4x² - 14x ⇒ 2x(2x - 7)

[tex]x\left(4x^2-9\right)\cdot \:2x\left(2x-7\right) = 2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex]

That leaves us with the following expression,

[tex]2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]

As you can see the " 2x - 7 " cancel out, and the " x² " cancel as well, leaving us with a further simplified expression,

[tex]2\left(4x^2-9\right)[/tex] ÷ [tex]3x+2[/tex]

Which can also be rewritten as [tex]8x^2 - 18[/tex] ÷ [tex]3x + 2[/tex] = [tex]\frac{8x^2 - 18}{3x+2}[/tex], in other words the first option.

Answer: 33

Step-by-step explanation: You add the two numbers underneath and on top is the answer

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{8 + 8i}}}}}[/tex]

Option D is the correct option.

Step-by-step explanation:

[tex] \sf{(3 + i) + (5 + 7i)}[/tex]

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.

That means, the expression remains the same.

Just remove the unnecessary parentheses

⇒[tex] \sf{3 + i + 5 + 7i}[/tex]

Collect like terms and simplify

⇒[tex] \sf{3 + 5 + i + 7i}[/tex]

⇒[tex] \sf{8 + 8i}[/tex]

Hope I helped!

The value of number after rounded to the nearest hundredth is, 5.42

In rounding a number into the nearest hundredth,

We look at the tenths place digit, If tenths place digit is 0, 1, 2, 3 or 4,

Then the number rounded to previous hundredth,

While, if the tenths place digit is 5, 6, 7, 8 or 9,

Then the number is rounded to next hundredth,

Here, the given number is,

⇒ 5.424

Here, Tenths place digit = 2,

Hence, it would be rounded to previous hundred,

Answer:

7

Step-by-step explanation:

The value of x in the equation -3-(-8)-(-2) = x is 7.

The correct option is 07.

When resolving expressions containing several operations, the procedure to follow is denoted by the acronym PEMDAS. "Parenthesis," "exponents," "multiplication," "division," "addition," and "subtraction" are all represented by the letters P through E.

Given information:

The given equation is described as -3-(-8)-(-2) = x.

To solve the equation as per the PEMDAS rule:

First, we need to simplify the terms within the parentheses: -(-8) is the same as +8, and -(-2) is the same as +2. Therefore, the equation becomes:

-3 + 8 + 2 = x

Next, we can simplify the addition and subtraction from left to right:

-3 + 8 = 5

5 + 2 = 7

Therefore, the value of x is 7.

Answer:

The length of the arc is [tex]\frac{5\pi}{3}[/tex] centimeters.

Step-by-step explanation:

The length of an arc ([tex]\Delta s[/tex]) with a given central angle is determined by the following expression:

[tex]\Delta s = \frac{\theta}{360^{\circ}}\cdot 2\pi\cdot r[/tex]

Where:

[tex]r[/tex] - Radius, measured in centimeters.

[tex]\theta[/tex] - Central angle, measured in sexagesimal degrees.

Given that [tex]r = 5\,cm[/tex] and [tex]\theta = 60^{\circ}[/tex], then:

[tex]\Delta s = \frac{60^{\circ}}{360^{\circ}} \times 2\pi \times 5\,cm[/tex]

[tex]\Delta s = \frac{5\pi}{3}\,cm[/tex]

The length of the arc is [tex]\frac{5\pi}{3}[/tex] centimeters.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, We know that;

The neurons are the structural and functional system of nervous system. It is composed of parts such as:

Dendrites – Branched structure located at the terminal of the cell body.

Cell body – It contains nucleus.

Nucleus – It is the controlling center of the cell.

Axon – Transports the signals from cell body to synapses.

Synapses – Sends the signal from one neuron to another neuron.
