Answer:
perimeter = 3y + 7 cm
Step-by-step explanation:
perimeter = y + y + y + 5 = 3y + 7 cm
Answer:
Step-by-step explanation:
Part 1: The domain is the set of values that represent the independent variable (in this case x) [0, 12].
And the meaning is the time, (the hours starting at midnight).
Part 2: The range is the set of values that represent the dependent variable (in this case y) [-2, 4].
And the meaning is the temperature outside measured every hour starting at midnight.
The open circle means the inequality will be greater than or equal to (≥) or less than or equal to (≤).
A closed circle means the inequality will be greater than (>) or less than (<)
An arrow pointing right to increasingly positive values means the inequality is getting greater (> or ≥)
A narrowing pointing left to increasingly negative values means the inequality is getting lesser (< or ≤)
So for this graph with an open circle and rightward pointing arrow, “x” will be some number on the number line greater than the first point of -38:
x > -38
if / means absolute value, then the answer is -3. The absolute value of 3 is 3, then you take the negative value of it, which is -3.
Btw, the absolute sign is ||, not //.
