Answer:

x=\frac{12+\sqrt{138}}{6}\:\:or\:\:x=\frac{12-\sqrt{138}}{6}

Step-by-step explanation:

f(x)=6x^2-24x+1\\\\0=6x^2-24x+1\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-24)\pm\sqrt{(-24)^2-4(6)(1)}}{2(6)}\\ \\x=\frac{24\pm\sqrt{576-24}}{12}\\\\x=\frac{24\pm2\sqrt{138}}{12}\\\\x=\frac{12\pm\sqrt{138}}{6}

slope is  \frac{1y-2y}{1x-2x}

so \frac{6 - 1}{3 - (-9)} and that is 5/12

If f(x) and its inverse function, fx), are both plotted on the same coordinate plane, what is their point of intersection?
Lubov Fominskaja [6]

Answer: (3, 3)

Step-by-step explanation:

the graphs of f and f^{-1 are flipped: if the point (x, y) is on the graph of f, then the point (y, x) is on the graph of f^{-1.

Any points of intersection will satisfy (x, y) = (y, x). A point that satisfies this property must have the same x and y coordinate. (Think about it.) The only point on f like that is (3, 3), so that is the point of intersection.

3. Emma said that when you multiply three negative decimals , the product will be positive . Use these numbers to answer the que
mina [271]

Using multiplication signal rules, it is found that:

A: Emma's statement is always false.

B: The result is always negative.

C: Emma's statement is always true.

The rule used for this exercise is as follows:

  • When two numbers of different signals are multiplied, the result is negative.
  • When two numbers have the same signal, the result is positive.

Part A:

  • Three numbers are multiplied, all negative.
  • The multiplication of the first two result in a positive number.
  • Then, this positive number is multiplied by a negative number, and the result will be negative, which mean that Emma's statement is always false.

Two examples are:

-2.5(-3.8)(-2) = 9.5(-2) = -19

-2.5(-2)(-0.7) = 5(-0.7) = -3.5

Part B:

The rule is that the result is always negative.

Part C:

  • The multiplication of the first two negative numbers result in a positive number.
  • Then, this positive number is multiplied by another positive number, and the result will be positive, which mean that Emma's statement is always true.

Two examples are:

-2.5(-3.8)(2) = 9.5(2) = 19

-2.5(-2)(0.7) = 5(0.7) = 3.5
