nA.Replace ''the difference with subtraction
B.Replace''the number of serving '' with a variable x.
C.Replace ''four'' with 4.
Step-by-step explanation: .
3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
Answer:
21/100 = .21 = 21%
Step-by-step explanation:
Answers:
choice A) y = 0x
choice D) y = 0/x
========================================================
Explanation:
Choice A is the same as y = 0 because 0x turns into 0. Multiplying 0 with any number always leads to 0.
Similarly, choice D is the same as y = 0 as well. Dividing 0 over any nonzero value leads to 0. Note the key term "nonzero" here. We cannot have 0 in the denominator. So x = 0 is not allowed for choice D.
So for any nonzero x, we have 0x and 0/x result in the same thing.

Extra info:
Choice B can be ruled out because something like x = 2 leads to y = 2.
Choice C is ruled out because we can never have 0 in the denominator.
E(t) is the elevation Maria is at at t minutes.
The expression to calculate the elevation is 1200 + 40t.
E(t) = 1200 + 40t
E(15) means the elevation Maria is at at time 15 minutes.
E(15) = 1200 + 40(15)
E(15) = 1200 + 600
E(15) = 1800
E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.
