For what value of n is -5n = 7-5(n-5)-32

Answers

Answer 1

Answer:

Answer:

-5n = 7 - 5(n - 5) - 32 is an identity, meaning it is true for all values of n.

Step-by-step explanation:

First, simplify the equation by distributing the -5 on the right side:

-5n = 7 - 5n + 25 - 32

Next, combine like terms on the right side of the equation:

-5n = (7 + 25) - (5n + 32)

-5n = 32 - 5n - 32

Now, notice that the terms "-5n" and "+5n" on the right side cancel each other out:

-5n = -5n

Since the left side is equal to the right side, the equation is true for all values of n. In other words, there is no specific value of n that satisfies the equation; it holds true for any value of n.

So, the equation -5n = 7 - 5(n - 5) - 32 is an identity, meaning it is true for all values of n.

Answer:

The correct answer is:

D) Q(2,1) R(3,-4) S(5,-3) T(4,0)

Step-by-step explanation:

When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.

Then the new coordinates of the parallelogram are:

Q(2,-1) R(3,-4) S(5,-3) T(-4,0)

the perimeter of a basketball court is 102 meters, and length is 6 meters longer than twice the width, what r length and width. what is width _m.

Answers

Perimeter = 2(l + w)

Thus,

102 = 2(l + w)

l = 6 + 2w

102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w

Thus, w = 15.

Length = 6 + 2w
= 6 + 30
= 36.

Thus, the length is 36 meters and width is 15 meters.
