<h3>
Answer:</h3>
y = -4.2x +34
<h3>
Step-by-step explanation:</h3>
The differences between adjacent y-values are -4.2 for all data points given, so the data is best modeled by a linear function with a slope of -4.2. The value for x=0 (the y-intercept) will be 4.2 higher than the value for x=1, so will be 34.
Thus the model can be ...
... y = -4.2x + 34

<em>Comment on the attached graph</em>
The graph shows an attempt to model the data with a quadratic function (the first on your answer list). The result is that the x² coefficient is zero, and the model is the equation of a line (as shown above).
Answer:
f(3) = - 38
Step-by-step explanation:
f(2) = 3 f(2 - 1) - 5 = 3 f(1) - 5 = 3(-2) - 5 = -6 - 5 = -11
f(3) = 3 f(3 - 1) - 5 = 3 f(2) - 5 = 3(-11) - 5 = - 33 - 5 = - 38
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4
Hope this helps :)
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33
