≅Answer:

See below.

Step-by-step explanation:

If we rotate the shape on the right 90 degrees counterclockwise we see they fit together, because they are congruent. They are exactly equal in size and shape - that's what congruent means.

So the following angles are equal in measure:

m < A = m < R

m < B = m < S

m < C = m < P

m < D = m < Q.

Corresponding sides are also equal in length:

Sides AB = RS

BC = SP

CD = PQ

AD = RQ.

Note: in the US the symbol ≅ is used for equality of sides. I think it means 'is congruent to'. (I'm from the UK).

Do you compare a negative decimal to a positive decimal?

Anika [276]

Answer:

Positive: Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is always greater than a negative decimal.

Negative: When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value.

All of it put together (same text as above):

Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is ALWAYS greater than a negative decimal. When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value.

There is $500 in Holly's bank account. She takes out $50 from her account each month but doesn't put money back in. What is the

galina1969 [7]

Answer:

The rate of change or slope m = -50

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the rate of change or slope

b is the y-intercept

Given that there is $500 in Holly's bank account.

Thus, the y-intercept b = 500

It is stated that she takes out $50 from her account each month but doesn't put money back in.

It means the rate of change or slope is decreasing.

Thus, the rate of change or slope m = -50

EXTRA BONUS!

We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

$y = mx+b$

y = -50x + 500

Here:

The slope m = -50

The y-intercept = 500
