Answer:
2nd option
{(-8, -2), (-4, 1), (0, -2), (2, 3), (4, -4)}
Step-by-step explanation:
For a function to exist, every value of input must have exactly one value of output.
The rest of the relations(1, 3, and 4) have 2 outputs for 1 input so they dont make a function.
Answer:
0.38
Step-by-step explanation:
Simply divide 19 by 50 on a calculator.
Ratio- 3: 2
3x + 2x = 150
5x = 150
x = 30
3x is the larger number so plug in the x value with 30.
3x
3 x 30
90
The larger number is 90.
Hope I helped.. ^^
Step-by-step explanation:
-3x + 7y = 5x + 2y (you subtract the 2y from both sides)
-3× + 5y = 5x (then add 3x to both sides)
5y = 8x (use x = - 5)
5y = 8x - 5 = -40 (both sides are divided by 5)
y = -8
answer is (-5, -8)
