Answer:
10 classrooms
Step-by-step explanation:
Divide it.
If each class needs 1 gallon, 10/1=10
The perimeter is 320. Just multiply 80 times 4
Answer:
{(2,5), (3,7), (2, 9) } is not a function
Step-by-step explanation:
It's because the domain, which is the x value, has the same number twice, which is 2.
Answer:
Step-by-step explanation:
2x + y = - 2
<u>x + y = 5 </u> Subtract to get rid of the y
x = -2-5
x = -7
The value of y is -8 if the x -24 and y varies directly with x, and If y = 4 when x = 12.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
The question is incomplete.
The complete question is:
If y varies directly with x, and If y = 4 when x = 12, how do you find y when x = -24?
y ∝ x (given)
y = kx
k is the constant of proportionality.
4 = 12k (y = 4, and x = 12)
k = 1/3
y = x/3
Plug x = -24
y = -24/3
y = -8
Thus, the value of y is -8 if the x -24 and y varies directly with x, and If y = 4 when x = 12.
