Solve for x: -5bracket(-3x+1)=-45
NikAS [45]

Answer:

Step-by-step explanation:

Equation

-5(-3x+1)=-45     If this is not correct, leave a comment please.

Solution

-5(-3x+1)=-45                     Divide by -5

-5(-3x + 1)/5 = -45/-5              

(-3x + 1) =  9                       Remove the brackets

-3x + 1 = 9                          Subtract 1 from both sides

-3x + 1 - 1 = 9 - 1                 Simplify

-3x = 8                               Divide by  -3

-3x/-3 = 8/-3

x = -8/3

or

x = -2.66

or

x = - 2 2/3

8. Which of these is not an integer 6 6 A 3 C E 3
Mnenie [13.5K]
An integer is a whole number. 

The answer isn't A, because 6/3=2 and 2 is a whole number.

The answer isn't C, because 6/2=3, and 3 is a whole number.

The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.

How do we derive the of laws of radicals?​
Yuki888 [10]
The laws for radicals are derived directly from the laws for exponents by using the definition a m n = a m n . The laws are designed to make simplification much easier. It is important to reduce a radical to its simplest form.

Which of the following is the maximum value of the equation y=-2x^2-3x+4
mylen [45]
Y=-2x^2-3x+4

dy/dx=-4x-3, d2y/dx2=-4

When the velocity, dy/dx=0, then y(x) is at an absolute maximum because the acceleration is a constant negative, -4.

dy/dx=0 only when -4x-3=0, -4x=3, x=-3/4

y(-3/4)=5.125

So the maximum value of y is 5 1/8
