I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x

10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46

This is all I know sorry. Hope you find some more help :)

Y = -2x^2

h = Xv = -B/2A = 0/-4 = 0.

k = -2*0^2 = 0.

V(0,0).

Use the following points for graphing:

Y = -2x^2.

(x,y)

(-2,-8)

(-1,-2)

V(0,0)

(1,-2)

(2,-8)

Y = -2x^2 + 4.

Evaluated:


(1) d - 6 = -8 -6

(2) -8 - 6 = -8 + (6)

First you change D into it's correct number which 6.

Second you take the subtraction sign and make it it's opposite.(Addition.)

Third you add -8 and -6 to get -14.
