Answer:
9.5%
Step-by-step explanation:
As a percentage of sales, Harris's earnings were ...
447/89400 × 100% = 0.5%
more than George's.
Harris's commission rate must be 9% + 0.5% = 9.5%.
Answer:
6y^2-12y-4
Step-by-step explanation:
(8y^2-5y+7) - (2y^2+7y+11)
(8y^2-5y+7)-2y^2-7y-11
Combine like terms:
6y^2-12y-4
The full answer is so long. I’m too lazy to do it but i can tell u how.
First write the equation of line AB then equation of line CD then compare the slope of both line AB and CD.
Answer (B) 2/3
Explanation: the multiplicative rate is the ratio of the values y(k)/y(k+1) (with k being the index). This ratio must be the same for the function to be exponential. We can take y(2)/y(1) = 4/6 = 2/3.
We can use 2/3 to verify the remaining entries:
x=3: 4*2/3 = 8/3 = y(3)
x=4: (8/3)*(2/3)=16/9=y(3)
