1 answer:

4 0

C=(x0,y0,z0)C=(x0,y0,z0) and radius rr.

(x−x0)2+(y−y0)2+(z−z0)2=r2(x−x0)2+(y−y0)2+(z−z0)2=r2

What are the solutions of 8x2 = 6 + 22x? Check all of the boxes that apply.

Sholpan [36]

Transpose all the terms in the left hand side of the equation. The equation then becomes,
8x² - 22x - 6 =0
Divide both sides of the equation by 2,
4x² - 11x - 3 = 0

In this equation, A = 4, B = -11, and C = -3

With the variables identified, the quadratic equation can be used to identify the roots,
x = (-B +/- √B² - 4AC) / 2A
The values of x in the equation are,
 x = 3 and x = -1/4
Thus, the one of the answer to this item is the third choice, x = 3.

PLEASE HELP ME Which of the following is the correct graph of the compound inequality 4p + 1 > −7 or 6p + 3 < 33? (1 poin

nikitadnepr [17]

The first inequality has solution
4p > -8 . . . . . . subtract 1
p > -2 . . . . . . . divide by 4
This is graphed as an open dot at -2, with shading to the right.

Neither inequality symbol includes "or equal to", so both dots are open dots. The appropriate choice is the first one:
a number line with open circles at negative 2 and 5 with shading in between
