Step-by-step explanation:

Select all of the following that are quadratic equations.

x² + 3x - 5 = 0 ✓

x² - x = 3x + 7 ✓

5x - 7 = 0 X

7x² + 14x = 0 ✓

x³ - 3x² + 1 = 0 X

x - 5 = 9x + 7 X

What is quadratic equations?

Quadratic equations is a equation that has a general form like "ax² + bx = c"

For example :

x² + 3x - 5 = 0

x² + 3x = 5

x² → ax²

3x → bx

5 → c

What are the vertical asymptotes of the function f(x) = the quantity of 3x plus 9, all over x squared plus 4x minus 12?
Zinaida [17]
In order to find the vertical asymptotes of a rational function you must set the denominator = 0 and solve for x.

If F(x) = (3x + 9) / (x^2 + 4x - 12), then set x^2 + 4x - 12 = 0 and solve for x.

(x + 6)(x - 2) = 0

x + 6 = 0 so then x = -6
x - 2 = 0 so then x = 2 

For this particular function, you have 2 vertical asymptotes.  x = -6 and x = 2

damaskus [11]

Answer:

13º

Step-by-step explanation:

We know a straight line makes 180, so the one opposite 63 is (180-63) which is 117.

We know the interior angles in a triangle make 180. We know two angles 50 and 117 and 50+117=167. 180-167=13.

kari74 [83]
In order to find an average, you have to add all the numbers and divide by the number of things you added.

120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

She spent an average of $114.56 each month on groceries.
