Answer:
Step-by-step explanation:
i am assuming that it wants you to find x so here is what i got.
I reccomend drawing it out
(3) 25+16÷4x= 13(x-1)
its in this formate because HI + IG will give you HG
25+4x=13x-13
25+13=13x-4x (moved the X's so they can be suptracted)
38=9x
38÷9 = 9x÷9
x≈4.2
same thing goes for the rest
(4) 16x-19+12x+9=0
16x+12x-19+9=0
28x-10=0
28x=-10/28
x= 5/14
(5) 18x-2-7x+3=0
18x-7x-2+3=0
11x-1=0
11x=1
x= 1/11
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
The relation between the variables is given by
This is a separable differential equation. Rearranging terms:
Multiplying by -1
Integrating
Where D is a constant. Applying expoentials
Where , another constant
Solving for P
With the initial condition P=0 when t=0
We get C=-M. The final expression for P is

Answer:
x=1.816298 or x=−1.162524
Step-by-step explanation:
Step 1: Multiply both sides by x^2.
x2=x4−3x3+8x2−16
x2−(x4−3x3+8x2−16)=x4−3x3+8x2−16−(x4−3x3+8x2−16)(Subtract x^4-3x^3+8x^2-16 from both sides)
−x4+3x3−7x2+16=0
(Use quartic formula)
x=−1.162524,1.816298
Check answers. (Plug them in to make sure they work.)
x=1.816298(Works in original equation)
x=−1.162524(Works in original equation)
