Answer:
C
The problem:
What can x not be so that the following is a function:
(8,5), (6, 8), (X, 11), (0, 12)?
Step-by-step explanation:
A set of points is a function if every element,x, in the domain is paired with one y from the range.
So basically we don't want any repeated x. x would be a repeat if x is 8 since it has already been paired with 5.
Summary we are saying x can't be 8 because x=8 is already paired with y=5 so we can't pair it with another different y.
Answer:
65,000
Step-by-step explanation:
6 1/2
= 13/2
= 6.5
6.5 * 10,000
= 65,000
<span>90+47=137 X is a right angle so it is going to equal 90 that is where the 90 came from.
180-137=43 to find y we have to subtract 180 (the sum of all triangles) by the sum of x and 47. Which ends up being 43.
X= 90
Y= 43</span>
The way I like to do this is divide the numerator(top number) by the denominator(bottom number) So you have one fifth, which is written as 1/5
1 divided by 5 is .2
ANSWER: .2
Hope this helped!!(:
In order to answer this, we will first need to combine like terms on each side. on the left, you can leave them alone. however on the right, we will need to combine 2 and 11. this is 13. the right side becomes 13-16y. after that, we can add 20y to both sides. that equals 15=13+4y now we can subtract 13 from both sides. 2=4y. then we divide by 4 on both sides to find y. y=.5
