r⁻⁸ s⁻⁵
using the rule x⁻ⁿ=1/xⁿ
r⁻⁸ s⁻⁵ = (1/r⁸)(1/s⁵)
Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.
Answer:
i think the answer is
8:22
Step-by-step explanation:
a) Write a linear function to model this scenario.
Answer:
Y=10x+25
Step-by-step explanation:
Hey so let’s take the number of hours we go boating as “x” and the TOTAL cost of this whole trip as “y”.
So obviously y would equal everything else so we can write
Y=
Next, it says we rent a canoe for $10 an hour. That means we would have to multiply 10 and x to find the cost of the rent.
So
Y=10x
Finally, it says we paid a registration fee of $25. This 25 is not affected by the number of hours or anything else. It is a fixed amount so we can represent it as
Y=10x+25
Hope this helps!
