Answer:

f'(x) = -f(x) = 9xy² - 6x²y + 5x³

Step-by-step explanation:

f(x) = –9xy² + 6x²y – 5x³

additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³

f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0

Pepsi [2]

Answer:

m = 8/5 or  1   3/5

Step-by-step explanation:

8 - 3m = 2m

add 3m to each side

8 - 3m+ 3m = 2m+ 3m

8 = 5m

divide by 5 on each side

8/5 = 5m/5

8/5 = m

This is nothing you need to solve, I just need a refresher about this type of math. For some reason I can't remember this right
SVEN [57.7K]

Answer:

Yes there is (but we like to remove it)

Step-by-step explanation:

Recall that x^1 = x, which represents x being multiplied by itself once, so you just have x. So, we usually take out the exponent 1 because it is not necessary since it's just the same as x.

Binomials have two variables (2a - 4b)

Trinomials have three variables (2a - 4b + 7c)

Polynomials are any equations that have 4 or more variables.

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation
zlopas [31]

The values are a = 7, b = -9, c = -18.

<u>Step-by-step explanation:</u>

The given quadratic equation is 7x^{2} - 9x = 18

The general form of the quadratic equation is ax^{2} + bx + c = 0

where,

  • a is the coefficient of x².
  • b is the coefficient of x.
  • c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ 7x^{2} - 9x - 18 = 0

Compare the above equation with general form ax^{2} + bx + c = 0

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.
