Answer:
x=2
Step-by-step explanation:
use distributive property: x^2+2x-1=4
remove the -1 by adding 1 on both sides: x^2+2x=5
use the guadratic fromula: ax²+bx+c=0
plug in the equation x^2+2x-5=0
a,b and c are the coefficients to plug into the formula
a=1, b=2, c=-1
Finally, you will find that x=2
The gradient formula is (y2-y1)/(x2-x1) aka rise/run, where by (x1,y1) and (x2,y2) are two points on the line.
In this case, the gradient
= -5-(-2))/(2-(-2))
= -3/4

I can do this in my head but I hope it is right but if not I'm sorry
Answer:
P( x = 2) = 0.4
Or 40%
Step-by-step explanation:
Given that wildcat has 0.5 probability of winning if they play nine times
Probability = possible outcomes ÷ required outcome
The required outcome = 9
Probability = 0.5
Let calculate the possible outcomes
Possible outcomes = 0.5 × 9 = 4.5 games
the probability that the Wildcats win two of the games will be
P( x = 2) = 2/4.5 = 0.44
Or 44%
