Step-by-step explanation:
slope is the rise over run
rise= X
run= Y
X/Y = slope
Start with

Separate the variables:

Integrate both parts:

Which implies

Solving for y:

Fix the additive constant imposing the condition:

So, the solution is

Fine the length BC using the cosine law. Google the law and sub it in
If you would like to find a linear model that represents the cost of a taxi ride, you can calculate this using the following steps:
2-mile taxi ride ... $5.00
4-mile taxi ride ... $9.00
x ... miles
y ... the cost in dollars
l ... constant
y = l * x + $1.00
$5.00 = l * 2 + $1.00
5 = l * 2 + 1
5 - 1 = l * 2
4 = l * 2
l = 4/2
l = 2
$9.00 = l * 4 + $1.00
9 = l * 4 + 1
9 - 1 = l * 4
8 = l * 4
l = 8/4
l = 2
The correct result would be y = 2 * x + $1.00.
Answer:
x=15, y=12
Step-by-step explanation:
Opposite interior angles have the same measure. Hence ...
... 62° = (4x+2)°
... 60 = 4x . . . . . divide by °, subtract 2
... 15 = x . . . . . . . divide by 4
And ...
6y° = 72°
... y = 12 . . . . . . . divide by 6°
