Answer:
I.M.S. infinite many solutions
Step-by-step explanation:
this will come out to be the same line.
The car is worth 17,200.
20,000x .14=2800
20,000-2,800=17,200.
1. To find the vertex of a parabolla whose equation is written in the standard form, you must apply the following proccedure:
2. You have:
y=-0.18x²+4.4x-12
a=-0.18
b=4.4
3. You must apply the following formula:
<span>
x=-b/2a
x=-4.4/2(-0.18)
x=-4.4/-0.36
x=12.22
4. When you susbtitute x=12.22 into the equation </span>y=-0.18x²+4.4x-12, you obtain:
y=-0.18x²+4.4x-12
y=-0.18(12.22)²<span>+4.4(12.22)-12
</span> y=14.88 feet
5. The answer is: The maximum height of the tunnel is <span>14.88 feet</span>
the domain of the graph is where on the x axis there is a graph.
here the domain, x, is less than or equal to 6, isnce it goes down on the negative side
the arrow means the line goes on forever, so
x<=6
(x is less than or equal to 6)
