You would add 2 and 4 which is 6. and that you would add 6 to -25 which would leave you with -19.

So it is basically -25+2+4 or -25+6.
Since it is a negative, adding a positive will move the number to the right on a number line.
-25+6=-19

Hope this helps! If you have any questions, just ask!

Answer:

1 2/4 or 1.5

Which are the solutions of x2 = –11x + 4?

Zarrin [17]

For this case we have the following polynomial:

$x ^ 2 = -11x + 4$

Rewriting the polynomial we have:

$x ^ 2 + 11x - 4 = 0$

From here, we can solve the polynomial using the quadratic equation

We have then:

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

$x=\frac{-11+/-\sqrt{11^2-4(1)(-4)}}{2(1)}$

$x=\frac{-11+/-\sqrt{11^2+16}}{2}$

$x=\frac{-11+/-\sqrt{121+16}}{2}$

$x=\frac{-11+/-\sqrt{137}}{2}$

Therefore, the solutions are:

$x=\frac{-11+\sqrt{137}}{2}$

$x=\frac{-11-\sqrt{137}}{2}$

Can you please tell me how to find the absolute maximum and absolute minimum values of a function???? Thank you!!!!!

valkas [14]

Answer:

Yes.

Step-by-step explanation:

In the Quadratic Equation, y = Ax² + Bx + C, two things could happen with your A:

Opens down → Maximum Value [-A]

Opens up → Minimum Value [A]

We can identify the minimum or maximum value of a parabola by identifying the y-coordinate of the vertex. You can use a graph to identify the vertex or you can find the minimum or maximum value algebraically by using the formula x = ⁻ᵇ/₂ₐ. This formula will give you the x-coordinate of the vertex.

I am joyous to assist you anytime.
