Answer:

-3

Three feet below the initial elevation

Step-by-step explanation:

The initial elevation is 224 feet.

We take descent to be negative and ascent to be positive.

The numerical addition expression is

224+-131+67+-163

We simplify this to obtain:

224-131+67-163=-3

The negative sign means Sally is 3 feet below his initial elevation

Answer:

  p = 70n -1500

Step-by-step explanation:

The slope-intercept form of the equation is ...

  p = 70n +b

We know that p = -800 for n = 10, so we can find b:

  -800 = 70·10 +b

  -800 -700 = b = -1500

The net profit equation is ...

  p = 70n -1500

What is the reason for statement 4 in this proof?
Naddika [18.5K]
It's the reflexive property because it's just relating it to itself (def. of reflexive)

As we all know: A=A, B=B, mx=mx, nothing changes.

So the answer is D

Which diagram shows lines that must be parallel lines cut by a transversal? 2 horizontal lines are intersected by a third line.
ivanzaharov [21]

Answer:

  (A)  At the intersection of the first line with the third line, the bottom left angle is 115 degrees. At the intersection of the second line with the third line, the uppercase left angle is 65 degrees.

Step-by-step explanation:

Alternate interior angles are supplementary when parallel lines are crossed by a transversal. The first description seems to be describing alternate interior angles. (See attachment)

_____

<em>Comment on orientation</em>

If the transversal is oriented horizontally, then the descriptions of the angles will be of different angles than assumed here.
