Answer:
The given equation cannot be solve but can be simplified.
Step-by-step explanation:
Given equation: 5x-6y+87z = 6x+96y-867z
We can only simplify the equation, but we cannot solve because there are three unknown variables and only one equation.
To successfully solve, we requires minimum of three equations.
lets simplify it:
- first place the similar variables at one place:
5x - 6x -6y - 96y +87z +867z =0
- Now perform the respective operation to the constants:
-x-102y+ 953z =0
⇒ x +102y + 953z =0
Which is the required simplification.
Answer:
<em>32x - 5y </em>
Step-by-step explanation:
27x - 5y + 5x = <em>32x - 5y</em>
Answer:
11/4 seconds
Step-by-step explanation:
We can see from the given equation that the height at the diving board is h = 3.
This is because the h(t) equation has that +3 at the end, which denotes the initial height of the diver, the height when he is standing on the board before jumping.
To find where h(t) = 3 is true, we need to set h(t) equal to 3 and solve for t.
h(t) = 3
h(t) = -4t^2 + 11t + 3 = 3
-4t^2 + 11t + 3 - 3 = 0
-4t^2 + 11t = 0
t*(-4t + 11) = 0
so h(t) = 3 when t = 0 and when t = 11/4 sec
we already know that at t = 0 the height is 3, it is the initial height given from the equation, so we want to use the other solution for t.
the diver is back at the height of the diving board at t = 11/4 sec
