Answer:
Step-by-step explanation:
Look at this as 2 separate expressions for now, being the first 2 terms and the last 2 terms:
Factor both of these individually, starting with the first one. The greatest common factor here is x², so factor that out:
Now the second equation. There isn't really a GCF here, but you still should factor out a -1 to get the x on its own.
Together, that leaves you with this:
This is actually another expression that can be factored. The GCF here is (x - 2):
Finally, you can expand that (x² - 1) further using this rule:
1 is equal to 1², so you can rewrite that term and then expand it with the rule above:
Answer:
x = 2, m = 10, a = 5
Comparing ratios of corresponding sides:
x/4 = 3/6 ==> x = 4*1/2 ==> x = 2
m/5 = 6/3 ==> m = 5*2 ==> m = 10
a/10 = 3/6 ==> a =10*1/2 ==> a = 5
P(J / R) = P (J and R) / P(R)
<span>0.8 = P (J and R) / 0.6 </span>
<span>P (J and R) = 0.6 * 0.8 = 0.48 [Probability John practicing and it is raining] </span>
<span>P(J / NR) = P (J and NR) / P(NR) </span>
<span>0.4 = P (J and NR) / (1 - 0.6) = P (J and NR) / 0.4 </span>
<span>P (J and NR) = 0.4 * 0.4 = 0.16 [Probability John practicing and it is not raining] </span>
<span>Hence; </span>
<span>Propability of John practicing regardless of weather condition is </span>
<span>P(John Practicing) = 0.48 + 0.16 = 0.64</span>
The "x" intercept is found when you plug in "0" for "y"
-6x + 3(0) = 18.9
-6x = 18.9 (Divide both sides by -6)
x = - 3.15
(-3.15, 0) is your x-intercept
Now plug in "0" for the x
-6(0) + 3y = 18.9
3y = 18.9 (Divide both sides by 3)
y = 6.3
(0, 6.3) is your y - intercept
1 pound 2/3 + 1/3 = 3/3 simplify to get 1
