If x = y then 3x = 3y property of equality

Mathematics
1 answer:
Debora [2.8K]3 years ago
6 0

Answer:

Multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.

I hope you find this helpful. :)

The length of the side of a square is equal to the perimeter of the square divided by four. Which shows the correct graph relati
serious [3.7K]

Answer:

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Step-by-step explanation:

Let

x ----> the perimeter of the square

y ---> the side length of the square

Remember that

The perimeter of the square is given by the expression

P=4b

where

b is the length side of the square

solve for b

b=\frac{1}{4}P

That means

A ordered  pair in the coordinate plane following the rule

(x,y) -----> (x,x/4)

The y-coordinate is equal to the x-coordinate divided by 4

y=x/4

therefore

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Because

For the point (4,1)

substitute in the linear equation the value of x

y=4/4=1 ----> is ok

For the point (8,2)

substitute in the linear equation the value of x

y=8/4=2 ----> is ok

Passing through point (4, 9) and perpendicular to the line y= -1/5x -3
Ratling [72]

Answer:

y = 5x-11

Step-by-step explanation:

The slope intercept form of a line is y =mx+b where m is the slope

y = -1/5 x-3

The slope is -1/5

Lines that are perpendicular have negative reciprocal slopes

-1 /(-1/5)

-1 * -5/1

5

The slope of the line that is perpendicular is 5

y=5x+b

Using the point (4,9)

9 = 5(4)+b

9 = 20+b

9-20 =b

-11

y = 5x-11

F = \frac{Gm_{1}m_{2}  }{d^{2} }

F x d^{2} = Gm_{1}m_{2}

d^{2} = \frac{Gm_{1}m_{2}}{F}

d = ±\sqrt{\frac{Gm_{1}m_{2}}{F} }
