Answer:
Step-by-step explanation:
3(x-2)(x-2)-8=5
3[x^2-4x+4]-8-5=0
3x^2-12x+12-13=0
3x^2-12x-1=0
use the quadratic formula to find x { -b+-sqrt(b^2-4ac) } / 2a
where a =3 , b=-12 and c =-1 from our equation above
{ -(-12)+- sqrt[ (-12)^2 - 4(3)(-1) ] } / [2(3)]
{ 12 +- sqrt [ 144 + 12 ] } / 6
{ 12 +- sqrt (156) } / 6
2 +- {sqrt ( 4 *13) } / 6
2 +- { 2 sqrt (13) } /6
2 +- sqrt (13) /3
there you go :)
Answer:
m(slope)=0
Step-by-step explanation:
To find slope given two points, use the formula m = y2 - y1/x2 - x1
(-10) - (-10)/(-3) - 5
0/-8
Anything being divided from 0, or divided by 0 is always 0, so the slope is 0.
Hope this helps.

Answer: 1/4 cups of butter
Step-by-step explanation:
You need 1/2 cups of butter for every 2 eggs.
When a question asks for the unit rate, it means what quantity of the other variable is needed per 1 unit of the variable in question.
In other words, how many cups of butter are needed per egg.
= Cups of butter / no. of eggs
= 1/2 ÷ 2
= 1/4 cups of butter
