Which set of ordered pairs does not represent a function? O {(-7, -8),(-7,5),(-6,0),(-1,8)} O {(-2,4), (6,-5),(-6, -9), (1, -5)} O {(8,-2), (3,9),(-1,-5), (-3,9)} O {(9,7), (2,7), (-8,-3), (-1,1)}​

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

#12 the answer is the third option
