Answer:
The third one
Step-by-step explanation:
The lines with a slope of 0 are horizontal lines because all the points on the line have the same y-coordinate on a graph. Using the slope formula on the line will give you 0.
Answer:
$2
Step-by-step explanation:
The first purchase is twice the value we seek:
2 sodas + 2 sundaes = $4
2 × (1 soda + 1 sundae) = $4
1 soda + 1 sundae = $2 . . . . . . . . . divide by 2
Answer: a.
and b.
.
Step-by-step explanation:
Let as consider,
Volume (in gallons) of water in the container = v
The number of minutes = t
(a)
From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is



Therefore, the required formula is
.
(b)
We have,

Multiply both sides by 3/2.



Therefore, the required formula is
.
The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)
(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)
=>
a) a 3 x 1 column =
| 3 |
| -4 |
| 6 |
b) xi + yj + zk
=> 3i - 4j + 6k
