Well, since we know $3.65 is how much ONE PACK of pencil costs, and k represents the packs of pencils PURCHASED, and x represents the COST per pack, your answer would be A. x = 3.65k. This is because to find out the total cost (x) of k amount of packs, you would multiply the cost (3.65) times k, (known as 3.65k), which would be expressed as x = 3.65k. =)
Hope I helped! ^-^
Lets look at the info we have:-
Ashley found 78 rocks on Monday.
Devin found 45 rocks on Tuesday.
Question:-
How many did they find both days?
The key word for this is "both". So we need to add here. Lets add:-
78 + 45 = 123
So, Ashley and Devin together found 123 rocks.
Hope I helped ya!! xD
F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235
Answer:
Cos x
