Answer:
The answer is 4/1
Step by step
So x=-3 y=4 and z=5 so i added - 3 +6 to get positive 3 and z - y to get postive 1. X +y gives you positive 1 also so if u join both you get an improper fraction 4/1
Answer:
Graph A
Step-by-step explanation
The problem: y=2x^2+8x+3
1) You will need to determine the direction of the parabola, If a > 0 then the parabola opens upward, if a < 0 then the parabola opens downward.
2) If when doing this you get an imaginary solution, you would have no x intercepts. The first thing you need to do is find the x intercepts, you can do this by plugging in 0 for y, so this would give you 0=2x^2+8x+3. Once you have this you start by subtracting 3 from both sides, dividing 8 from both side, etc. (If you would like me to elaborate don't hesitate to ask!)
3) To find the graphs y intercept you plug in 0 for x, which gives you y=2(0)^2+8(0)+3, you do the same thing you did during the previous step for y. (Once again, I am willing to elaborate further if you need!)
4) You then need to find the vertex (h,k)
To find h: h= -b/2a
To find k: k = a(h)2 + b(h) + c
5) Once you've worked through this you can graph the point!
Hope this helped!
The volume of the bed of the truck is 2.5 x 1.5 x 1.0 = 3.75 cubic meters.
total trips = 7 / 3.75 = 1.87, round up to 2.
They will need to make 2 trips.
Answer:
10
Step-by-step explanation:
. Then 
. So if we can find a closed form for 
, in terms of
