Answer:
2x+ 2.1 = 7.5
x=2.7
Step-by-step explanation:
The perimeter of an isosceles triangle with sides x and y is
2x+y = P
I put y as the single side since the question said y is the shortest side. It should say shorter sides if the two sides with the same length are smaller than the third.
We know y =2.1 and P = 7.5
Substituting these values in, we get
2x+ 2.1 = 7.5
Subtract 2.1 from each side
2x+2.1 -2.1 = 7.5 -2.1
2x= 5.4
Divide each side by 2
2x/2 = 5.4/2
x = 2.7 m

Answer:
w=30.5 y=29
Step-by-step explanation:
2w=61 so w=30.5
61+y=90 so y=29
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.
The correct answer is 99.
