The answer should be 1 and three
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. ... This is a function since each element from X is related to only one element in Y.
Answer:
7c + 5
Step-by-step explanation:
(8c+8)–(c+3)
8c - c = 7c
8 - + 3 = 5
7c + 5
Y = -3/4x - 2
Add 2 and subtract y
-3/4x - y = 2
No fractions or negative
Multiply all by 4
-3x - 4y = 8
Now multiply all by (-)
Solution: 3x + 4y = -8
Answer:
x =
, y = 
Step-by-step explanation:
1. Isolate for x in one of the equations:
2x = 9x - 14y
2x-9x = 9x-9x -14y
-7x = -14y
-7x/-7 = -14y/-7
x = 2y
2. Substitute 2y in for x in the second equation:
9(2y) = 40 - 14y
3. Simplify:
18y = 40 - 14y
4. Isolate for y:
18y+14y = 40 -14y+14y
32y = 40
32y/32 = 40/32
y = 
5. Substitute the new y-value into the simplified expression x = 2y:
x = 2(5/4)
x =
