Britney is solving a quadratic equation. her first

step is shown below.

problem: 3x^2– 8-10x = 3(2x + 3)

step 1: 3x2^2 - 10x - 8 = 6x + 9

which two properties did britney use to get to step

1?

i addition property of equality

ii. commutative property of addition

iii. multiplication property of equality

iv. distributive property of multiplication

over addition

1) i and ii

2) i and iv

3) ii and iii

4) ii and iv

where is the picture

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

i believe it is 2
