Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows. Step

1: m = StartFraction 13 minus 25 Over negative 4 minus (negative 7) EndFraction = StartFraction negative 12 Over 3 EndFraction = negative 4. Step 2: y = negative 4 x + b. 25 = negative 4 (negative 7) + b. 25 = 28 + b. 25 minus 28 = 28 + b minus 28. b = negative 3. Step 3: y = negative 3 x minus 4 What was Brooke’s error?

R, S, Q and P are the midpoints of OC, CB, BA and OA respectively.
Stolb23 [73]

Answer:

See below.

Step-by-step explanation:

Draw segment OB.

In triangle OBC, points R and S are the midpoints of sides OC and BC, respectively. That makes RS parallel to OB.

In triangle OBA, points P and Q are the midpoints of sides OA and BA, respectively. That makes PQ parallel to OB.

Since segments RS and PQ are parallel to segment OB, then RS and PQ are parallel to each other.

Answer:

z = 7

Step-by-step explanation:

Based on the midsegment theorem of a triangle, the length of the midsegment of the triangle (z) = ½ of the length of the 3rd side of the triangle (14)

Thus:

z = ½(14)

z = 7

Fernando purchased a new motorhome for $180,000, but the motorhome will depreciate
Dmitry_Shevchenko [17]

Your answer would be 122,400.

<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.

It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.

Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.
