Mathematics

Vinil7 [7]3 years ago
4 0

2z + 9.75 -7z =  -5.15

2z - 7z + 9.75 = -5.15

-5z + 9.75 = -5.15

-5z + 9.75 - 9.75 = -5.15 - 9.75

-5z = -14.9

-5z/-5 = -14.9/-5

z = 2.98

I hope this helps

What is diffrentiation?

  • A technique for determining a function's derivative is differentiation.
  • A technique for determining a function's derivative is differentiation. Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of variation based on a particular variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time.
  • In mathematics, differentiation is used to determine change rates. 

Differentiating the given equation with respect to x,

Given equation,

y= 55x+ 300

\frac{dy}{dx} =\frac{d(55x+300)}{dx} = 55+0 =$55 dollars.

The amount when x=0 yields starting amount,

y=55(0)+300=300
