Answer:
First, you have to simplify the inequality and solve for x.
x + 2x + 6 < 50
3x + 6 < 50
3x < 44
x < 14 2/3
So, you now have another set of numbers, {13, 14, 15, 16, 17}, and you know x must be smaller than 14 2/3. The only two numbers in that set that works are 13 and 14, making A: {13, 14} the correct answer.
Variable varies or changes
constatant term doesn't change
examples
variables can change so example
x>10
x can be 11 or 33 or anythign bigger than 10
constants are no fun
they don't change an are boring, like
3 or 8, it just stays that way
Answer:
(−4, −8), because the point satisfies both equations
Step-by-step explanation:
Line A
y = x - 4
Line B
y = 3x + 4
If we equate those 2 equations
x - 4 = 3x + 4
2x = -8
x = -4
y = -8
Y is equal to 105 because you divide 42 by 8 and get 5.25 (the amount it increased). then you multiply by its previous version 20 to get 105.
