Answer:
the answer is zeroo
Step-by-step explanation:
Answer: Part A: y= -1200x +25000 this is because it decreases 1200$ a year that is your rate of change and it started at 25000 that is your y-intercept
Part B: question a would be 46000$ because that’s where the zero is which is when he bought it question b is 3000$ because that is how much the table decreases with each year
Step-by-step explanation:
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
Answer:
The minimum value of the width is 15 ft and the maximum value of the width is 30 ft
Step-by-step explanation:
Let
x -----> the length of the deck
y ----> the width of the deck
we know that
The perimeter of the deck is equal to


so


-----> equation A
The area is equal to
-----> inequality B

Solve the quadratic equation by graphing
The possible width of the deck are the values of y in the interval
[15,30]
All real numbers greater than or equal to 15 ft and less than or equal to 30 ft
see the attached figure
The minimum value of the width is 15 ft and the maximum value of the width is 30 ft
The degree of the equation is 12 which means it's even. The leading coefficient is 7 which means it's positive. According to the these, the end behavior of the graph is:
<span><span>f<span>(x)</span>→+∞, as x→−∞
As x approaches negative infinity, the value of f(x) approached positive infinity
</span><span>f<span>(x)</span>→+∞, as x→+<span>∞
</span></span></span><span>As x approaches positive infinity, the value of f(x) approached positive infinity</span>
