This is a quadratic equation:
y = a x² + b x + c, a > 0 ( opening upward )
The zeroes are: ( - 1 , 0 ) and ( 4, 0 ).
y = a ( x - x 1 ) ( x - x 2 )
y = a ( x + 1 ) ( x - 4 )
y = a ( x² - 4 x + x - 4 )
y = a ( x² - 3 x - 4 )
Answer:
The correct answer is 
Step-by-step explanation:
A fair coin is tossed three times in a succession the sample space is shown where h represents a head and t represents a tail.
Let the experiment A denote that we get exactly one tail in three successive toss of a coin.
Sample space = { hhh, hht, hth, thh, tth, tht, htt, ttt} = 8
Favorable sample = { hht, hth, thh } = 3
Probability of the A =
=
= 0.375.
Thus the probability of getting exactly one tail in three successive toss of a fair coin is given by 0.375
The slope of the line would be 3/2 because the slope formula would be y2-y1/x2-x1 so 3-0=3 and 4-2=2 so 3/2
Hope this helps

Rewrite -1 as a fraction

Cross multiply

Distribute the -1

Add both sides by ax

Subtract both sides by 3

Divide both sides by 3a

Simplify

That's the value of x respect to a. Let me know if you need any clarifications, thanks!
