It is a function. This is because the x's don't repeat.

This indeed is both a relation and a function because it is a set of ordered pairs and the x-axis does not repeat itself.

3x+2=5x What is the answer for this solving equations with variables on each side
Yanka [14]
3x +2= 5x
-3x
2= 2x
/2
1= x
So first I got all the x’s on one side and the whole numbers on the other side. So we had 2 on one side and 2x on the other. From there we divided by the number of x’s which was 2 so we can get one x only. So 2/2= 1 so x =1

Through: (2, 2), parallel to y = x +4​
dexar [7]

Answer:

y = x

Step-by-step explanation:

We can use slope-point form.

(y-y1) = m(x-x1)

m is a slope. If the line is parallel than slopes are the same.

y = x + 4, for this line slope = 1, so for line we have to find slope is also 1.

(y-y1) = m(x-x1)

m=1, x1 = 2, y1 = 2

(y - 2) = 1(x-2)

y - 2 = x - 2

y = x

dalvyx [7]

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

(c) |BC|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

<u>Definition</u>

  • A <u>radius </u>is a line drawn from the center of a circle to its circumference.
  • A <u>segment </u>is a line that connects two points.
  • A <u>diameter</u> is a chord which passes through the center of the circle.
  • A <u>chord</u> is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|

Solve for y x=y^2+4y
Lorico [155]
x=y^2+4y\\ y^2+4y-x=0\\\Delta=4^2-4\cdot1\cdot(-x)=16+4x\\\\&#10;1.\ \Delta0\\&#10;\sqrt{\Delta}=\sqrt{16+4x}=\sqrt{4(4+x)}=2\sqrt{x+4}\\&#10;y_1=\frac{-4-2\sqrt{x+4}}{2\cdot1}=-2-\sqrt{x+4}\\&#10;y_2=\frac{-4+2\sqrt{x+4}}{2\cdot1}=-2+\sqrt{x+4}\\

-----------------------------------------------------

x=y^2+4y\\ y^2+4y-x=0\\&#10;y^2+4y+4-4-x=0\\&#10;(y+2)^2=x+4\\&#10;y+2=\sqrt{x+4} \vee y+2=-\sqrt{x+4}\\&#10;y=-2+\sqrt{x+4} \vee y=-2-\sqrt{x+4}\\

An international company has 25,600 employees in one country. If this represents 19.3% of the company's employees, how many empl
Elden [556K]

Answer:

Step-by-step explanation:

An international company has 25,600 employees in one country. If this represents 19.3% of the company's employees, then the total number of employees that the international company has would be 100%.

To determine the actual value for 100%,

Let x represent the total number if employees that the international company has. Therefore

19.3/100 = 25,600/x

Cross multiplying,

19.3x = 25600 × 100 = 2560000

x = 2560000/19.3 = 132642.49

The total number of employees is approximately 132643
