Answer: 20
Explanation: The equation is 175 - 15 (160) and then divide it by 8 (20)
A horizontal line test would show that the equation is a relation but not a function (C)
Answer:
A+B only 10% = 1250/2x1-2 = 0 1250/76 = x 1.6 + (+1=2.5%) 90% vote = 1226 95%=1302 99% 1377 5% 1188 2.5% 1169
Step-by-step explanation:
A= deduct this from sample size B it is usually 5 of the vote% so in comparison wont hinder the negative we deduct 1 from the 5%. B. Margin of error is 2.5% deduction comparison was Mayor was asking for a negative outcome with a positive vote. which is biased alone. Loss of confidence due to margins.
I don’t understand the question
Answer:
(There's actually a few ways of solving this, but here's one)
Multiplying the second equation by 2.
EDIT: Because the question says it will eliminate a variable "when combined", implying adding the systems together. The actual correct answer is multiplying the second equation by -2.
(multiplying the second equation by -2 is the actual answer, my apologies)
Step-by-step explanation:
So it's clear that they are referring to the elimination method and not the substitution method for solving systems of equations.
In the elimination method, you subtract 2 equations in the hopes of the elimination of a variable.
If you multiply the second equation, 2x + 6y = 24, by 2, you get, 4x + 12y = 48.
This is helpful because when you subtract this from the first one, you eliminate x.
4x + y = 4
-(4x + 12y = 48)
is
-11y = -44
