Find the number of real number solutions for the equation.x2 − 2x + 9 = 0

Talja [164]

Hi there!

We can use the discriminant of the quadratic formula to find the number of real solutions to this (or any other quadratic) equation.

The discriminant can be found by plugging in the data from the equation into the following formula:
$d = {b}^{2} - 4ac \\ with \: y \: = a {x}^{2} + bx + c$

When we fill in the data from the question we get
$d = ( - 2) {}^{2} - 4 \times 1 \times 9 = 4 - 36 = - 32$

Since d < 0 the equation has zero real solutions.

Arrange the given polynomial in descending order. 9x? + 9x +3+2x

WARRIOR [948]

20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!

Solve the inequality 4y+3x-y>-6x+12

Nady [450]

First, combine like terms.

3y+3x>-6x+12

Next, because there can not be the same variable on both sides, add 6x to both sides.

3y+9x>12

Find the length of the missing side (nearest tenth). 25 yd 37 yd

Ket [755]

Answer:

27.3 yards

Step-by-step explanation:

Since this triangle is a right triangle, this can be solved using the equation:

a^2 + b^2 = c^2

c^2 is the side opposite to the right angle (37)

So, you need to change the equation to where it is set equal to b^2.

Subtract a^2 on both sides.

b^2 = c^2 - a^2

Now, plug in the numbers you have.

b^2 = 37^2 - 25^2

Simplify.

b^2 = 1369 - 625

b^2 = 744

Now, to find b, take the square root of 744.

√744 = 27.3
