(-4,5)(3,-9)
slope = (-9 - 5) / (3 - (-4) = -14 / (3 + 4) = -14/7 = -2
y = mx + b
slope(m) = -2
use either of ur points...(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -2(-4) + b
5 = 8 + b
5 - 8 = b
-3 = b
so ur equation is : y = -2x + (-3) which can be written as : y = -2x - 3
Answer:
JK = 18
Step-by-step explanation:
LK = x - 1
KJ = x + 11
LJ = LK + KJ = x - 1 + x + 11
-> LJ = 2x + 10
LM = 12

Answer:

Step-by-step explanation:
Given

Calculate the perimeter of IJH
<em>See attachment for illustration</em>
From the attachment,
I = mid of FH.
So:



J = mid of GH.
So:



Perimeter IJH is then calculated as:



In statistical methods, the significance level is a value that is used as a criterion for rejecting a null hypothesis. It used by first looking at the differences between the experimental results and from there the null hypothesis would be determined. Then, we assume that the null hypothesis is true, the probability of the differences is computed by using statistical tools. If the computed probability is less than or equal to the value of the significance level, then you conclude that the null hypothesis should be rejected and that the results are statistically significant. Usually, a significance level of 1% or 5% is used.
