Answer:
Step-by-step explanation:
We are given the following in the question:
Let the equation:
be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f
Temperature at 12000-foot level = 49 f
Solving the two equation, we get,
Thus, we can write the linear equation as:
Answer:
The length of side AC is 5 units.
The areas of triangle ABC is 10 square units.
Step-by-step explanation:
From point A (1,3) to point C (1,-2) is 5 units
To check this:
3 - (-2) = 3 + 2 =5
We're subtracting since the point went down (from positive 3 to negative 2)
Now for the area:
Area formula for a triangle: bh =
⋅b⋅h
We already found the height (length) : 5
The base is from point C (1,-2) to point B (5,-2), which is 4 units
To check this:
5 - 1 = 4
Now that we have found the base and height, Let's solve:
⋅4⋅5 =
⋅20 = 10
Our area is 10 square units.
Hope that helps :)
