Answer:
The equation of the line is 
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we have
(-2,11) and (9,22)
substitute
step 2
Find the equation in slope intercept form
where
m is the slope
b is the y-intercept
we have
substitute in the equation and solve for b
Adds 2 both sides
The equation of the line is
To factor this you need values that add up to 2 and multiply to -15
So you get 5,-3 then you put it into your equation for you b value
X^2+5x-3x-15
Then you can factor by grouping
X(x+5)-3(x+5)
So your factors are
(X+5)(x-3)
Answer:
Should be a 50/50 chance
Step-by-step explanation:
When you flip a coin there are 2 possible chances, heads or tails. That means that out of 100 there should a 50/50 chance to get both. By Tegan getting 63 heads it show how the mentailty that it should be a perfect 50/50 chnace to get heads is not real and therefore not fair.
(but in real life this is what happens. Its not fair).
Answer:
17.4
Step-by-step explanation:
p = -0.4
substitute p into equation
-5(-0.4) + 15.4 =
2 + 15.4
17.4
-0.9 then 0.74. -0.9 then 0.7
5. -9.87 then 9.08
