Answer:
Ratio of Quentin new income to Sam new income is ![\frac{11}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B12%7D)
So option (a) will be correct option
Step-by-step explanation:
Let Rex income is 100
Then Paul income is 40 % less than Rex income 100 - 100×0.4 = 100-40 = 60
And Quentin's income is 20 % less than Paul income
So Quentin's income is 60 - 60×0.2 = 60-12 = 48
Sam income is 40% less than Paul income
So Sam income = 60 - 60×0.4 = 60 - 24 = 36
Now Rex give 60% income Sam
So Sam new income = 36 + 100×0.6 = 60+36 = 96
And Rex give 40% of his income to Quentin's
So Quentin's new income = 48 + 100×0.4 = 40+48 = 88
Now ratio of Quentin's new income to the Sam new income ![=\frac{88}{96}=\frac{11}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B88%7D%7B96%7D%3D%5Cfrac%7B11%7D%7B12%7D)
So option (a) will be correct answer
I believe the answer to this question is A) -8. I hope this helps!!
Answer:
Graph the polynomial in order to determine the intervals over which it is increasing or decreasing. Increasing on: (1,∞) ( 1 , ∞ ). Decreasing on: (−∞,1) ( - ∞ , 1 ).
Step-by-step explanation:
Answer:
x = 1
y = -1
Step-by-step explanation:
A*B= (4y-8 3x-3)
1-) (4×2)+(3×y)= 3y+8
2-) (4×x)+(3×(-1))= 4x-3
AB=C
(3y+8 4x-3)=(5 1)
So
3y+8=5 ; y= -3/3 = -1
4x-3=1 ; x=4/4 =1
GCF is the Greatest Common Factor. It would be the largest number that can divide evenly into all the numbers you need to find the GCF in.
exapmple GCF for 12 and 16
12: 1, 2, 3, 4, 6, 12
16: 1, 2, 4, 8, 16
the largest common number is 4, so 4 is the GCF of 12 & 16
LCM = Least Common Multiple is the smallest number ( other than zero) that is a multiple of both
LCM of 3 and 5
3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20
the first common number is 15, so this is the LCM of 3 & 5
