Answer:
<u>f(x)=x²-2x-2</u>
Step-by-step explanation:
<em><u>f(x)=ax²+bx+c</u></em>
f(0)=-2 => c= -2
f(1)= -3=> a+b-2=-3; a+b=-1
f(2)= -2; 4a+2b-2=-2; 4a+2b=0; 2a+b=0
a+b=-1 and 2a+b=0
2a+b-(a+b)=0+1=> a=1
2+b=0=> b=-2
f(x)=x²-2x-2
Step-by-step explanation:
5x+23=0
5x=23
x=23-5
(x=7)
Answer:
26%
Step-by-step explanation:
total gum balls 200
52/200 = x/100
52×100=5200
5200÷200=26
\left[y \right] = \left[ 0\right][y]=[0] I hope helping with u
