Answer:

A) all real values of x

B) distributive property

Step-by-step explanation:

A)

5x + 3(x − 5) = 6x + 2x − 15

5x + 3x - 15 = 8x - 15

8x - 15 = 8x - 15

-15 = -15

This is an identity, true for all real values of x

Answer:

infinite solutions

Distributive Property

Step-by-step explanation:

5x + 3(x − 5) = 6x + 2x − 15

Distribute

5x+3x -15 = 6x+2x -15

Combine like terms

8x -15 = 8x-15

Subtract 8x from each side

8x-8x-15 = 8x-8x-15

-15=-15

This is always true so there are infinite solutions

We used the Distributive Property

And the Subtraction Property of Equality

Prove the diagonals of the square with vertices P (0,4), Q (4,4), R (0,0) and S (4,0) are perpendicular bisectors of each other.
Aneli [31]

Answer: The slope of diagonal PS is -1. The The slope of diagonal QR is 1. The midpoint of PS is (2,2). Midpoint of QR is (2,2).

Explanation:

The given vertices are P (0,4), Q (4,4), R (0,0) and S (4,0).

If a line passing through the point (x_1,y_1) and (x_2,y_2), then the slope of the line is,

m=\frac{y_2-y_1}{x_2-x_1}

The slope of diagonal PS is,

m_1=\frac{0-4}{4-0}= \frac{-4}{4} =-1

The slope of diagonal QR is,

m_2=\frac{0-4}{0-4}= \frac{-4}{-4} =1

The slope of both diagonals are 1 and -1, therefore the product of their slopes is -1. So, the diagonals are perpendicular to each other.

The formula for midpoint is,

midpoint=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

The midpoint of PS is,

\text{midpoint of PS}=(\frac{0+4}{2} ,\frac{4+0}{2})=(2,2)

The midpoint of QR is,

\text{midpoint of QR}=(\frac{4+0}{2} ,\frac{4+0}{2})=(2,2)

The midpoint of both diagonals are same, therefore diagonals are bisecting each other.

Therefore, the slope of diagonal PS is -1. The The slope of diagonal QR is 1. The midpoint of PS is (2,2). Midpoint of QR is (2,2).
