I think the answer is : x = -5.25
MaRussiya [10]2 years ago

Answer:

x=-5.25

Step-by-step explanation:

Original equation:

2(3-x)-1.4(5-2x)=2x+5.3

Distribute:

6-2x-7+2.8x=2x+5.3

Group like terms:

(6-7)+(2.8x-2x)=2x+5.3

Add like terms:

-1+0.8x=2x+5.3

Add 1 to both sides

0.8x=2x+6.3

Subtract 2x from both sides

-1.2x=6.3

Divide both sides by -1.2

x=-5.25

Determine the period of the following trigonometric function.<br> y=4cos(8πx)
Diano4ka-milaya [45]

The period of y = 4 cos(8πx) is 2π/(8π) = 1/4, since

cos(x - 2π) = cos(x)

and if we replace x with 8πx, we get

cos(8πx - 2π) = cos(8πx)

and

8πx - 2π = 8π (x - 1/4)

Which of the following functions would best model the situation above?
amid [387]
Usually bacteria expansion is modeled with exponential function.
Absolute value is not the correct answer since it models linear growth. 
Logarithmic is not the correct answer since it has an asymptote in the direction of the x axis. 
I will answer to this question "Polynomial" since it is likely to represent bacteria growth.
