Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
(1,-1)....x1 = 1 and y1 = -1
slope(m) = 4
now sub
y - (-1) = 4(x - 1) =
y + 1 = 4(x - 1) <=====
The ones in the bracket are a similar way of vectors.
hope that kinndaaa helps sorry xoxo
Answer:
Ellen spent $2.40 on her lunch.
Step-by-step explanation:
Let,
x be the total amount Ellen had.
Amount spent on lunch =
Amount left after lunch =
Amount spent on movie =
Amount she has left = $1.20
Total amount = Lunch amount + Movie amount + Amount left
x =
Amount spent on lunch = = $2.40
Hence,
Ellen spent $2.40 on her lunch.
Given that E is a point between Point D and F, the numerical value of segment DE is 46.
<h3>What is the numerical value of DE?</h3>
Given the data in the question;
- E is a point between point D and F.
- Segment DF = 78
- Segment DE = 5x - 9
- Segment EF = 2x + 10
- Numerical value of DE = ?
Since E is a point between point D and F.
Segment DF = Segment DE + Segment EF
78 = 5x - 9 + 2x + 10
78 = 7x + 1
7x = 78 - 1
7x = 77
x = 77/7
x = 11
Hence,
Segment DE = 5x - 9
Segment DE = 5(11) - 9
Segment DE = 55 - 9
Segment DE = 46
Given that E is a point between Point D and F, the numerical value of segment DE is 46.
