Solve the following equation 3 by X + 1 is equal to 5 by 2 X linear equation​

Mathematics
1 answer:
dangina [55]3 years ago
3 0

Answer:

  x  = 5

Step-by-step explanation:

A by B is simply \frac{A}{B}

    3 by x + 1 is \frac{3}{x + 1}  

    5 by 2x is \frac{5}{2x}  

So, the equality is ;

                \frac{3}{x + 1} = \frac{5}{2x}  

Cross multiply and solve the inequality;

         3(2x) = 5(x + 1)

         6x  = 5x + 5

          6x -5x = 5

              x  = 5

What is the length of the hypotenuse
Liula [17]

Answer:

20

Step-by-step explanation:

To find Hypotenuse: Pythagorean Theroem

a^2+ b^2= c^2

The legs are A and B

The side that is directly across from the Right angle is C

12^2 + 16^2 =C^2

144+256=400

400 = c^2

Square root on both sides to get rid of c^2

The square root of 400 is 20

c=20

What is the image of point (4, 3) if the rotation is 90º ? Please and thank you.
Zielflug [23.3K]

Answer:  (-3, 4)


Step-by-step explanation: Given point coordinate (4,3).

We need to rotate the given point about 90º.

<em>In order to find the new coordinates of rotation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).</em>

Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.


In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.

On applying rule (h, k) ---> (-k,h), we get

(4,3)  ---> (-3, 4)

10x•5y•10=30 find the x and y intercept
GalinKa [24]
Y=mx + b
10x.5y.10=30
10x.5y=30-10
10x.5y=20
5y= -10x + 20
5/5 = -10/5(x) + 20/5
Y= -2x +4
