Answer:
take the answer on picture which I attached with your question
Answer:
year.
a. Write a function for the value of the truck, x years
after Mr. Patton has bought it.
b. What year will the truck be paid off using this
model?vStep-by-step explanation:
We can solve for the 3 triangle sides.
The left side is easy 6.
Second side² = 7² + 4²
Second side² = 49 + 16
Second side = square root (65)
Second side =

<span>
<span>
8.0622577483
</span>
</span>
</span>
Third Side² = 7² + 2²
Third Side² = 53
Third Side =

<span>
<span>
7.2801098893
</span>
</span>
</span>
When we know 3 sides, we use Heron's formula for calculating area:
Perimeter =

<span>
<span>
21.3423676376
</span>
</span>
</span>
Semi-Perimeter =
<span>
<span>
<span>
10.6711838188
</span>
</span>
</span>
Using Heron's Formula
area = square root (<span>10.6711838188 * </span><span>4.6711838188 * </span>
<span>
<span>
<span>
2.6089260705
</span>
</span>
</span>
*
<span>
<span>
<span>
3.3910739295

)
area = square root (441)
area = 21
Yes, it's just that "easy". LOL
Answer:
Step-by-step explanation:
Remark
I'm not sure I know what you intend for the slope. I will take it as 12/3 = 4
If that is the case then what you have so far is
Solution
y = 4x + b
The given point determines b
<em>Givens</em>
x = 3
y = 2
<em>Given point</em>
2 = 4*3 + b
2 = 12 + b
b = 2 - 12
b = -10
The equation is y = 4x - 10
Length of the segment is 1.5 cm (since the picture is small)
The scale is 1.5 : 1 or 1.5/1
