If x-7 =0
Then x =7
Substitute x=7 into f(x):
2(7)^2 - 11(7) + k
= (98-77)+k
= 21+k
Therefore k=-21 because 21+(-21)=0
Answer:
C.
Step-by-step explanation:
The relationship is proportion if y/x is constant.
So it is C because 12/4 = 15/5 = 18/6 = 3.
Answer:
1.2 dollars
Step-by-step explanation:
You have to divide the dollar count by the pound count.
So basically:
6/5
This gives you 1.2 dollars.
When you do unit rate, you just have to divide one value by the other value.
The value you divide by, and the value you divde, vary depending on what the question asks.
For instance, if this question asked what the pound count for 1 dollar would be, you would end up divide the 5 pounds by 6 dollars(5/6) instead of divideing the 6 dollars by 5 pounds like we did above(6/5).
Hope this helps!
Can you please give me brainiest :D
