4 tootsie rolls, 3 lollipops, 5 hersheys kisses, 6 starbursts......for a total of 18 pieces of candy.
now...there are 3 lollipops.....and 18 total pieces of candy.....so the probability of selecting a lollipop is : 3/18 which reduces to 1/6
Answer:
The roots are real and unequal (3, -3)
Step-by-step explanation:
x²-9=0
ax²+bx+c=0
Comparing we get,
a= 1
b= 0
c = -9
Determinant: b²-4ac
= 0² - 4(1)(-9)
= 36>0
D > 0
Therefore, the equation has real and unequal roots.
Algebraic identity:
x² - a² = (x-a)(x+a)
Using this identity
x²-9 = (x+3)(x-3)
Roots are 3 and -3 which are real and not equal to each other
Hope this answer helps you ..
Y= -2x-1 is the asnwer i think
hope this helped
