The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
-6 and -4 are your inputs -2 and 7 are your outputs
Answer:
3+3tt=total amount of snow
Step-by-step explanation:
y=mx+b is used to show increase
In this case, b is the original 3 inches of snow. m is the constant growth, and x is tt, or the amount of time it is being compared to. y is the total.
Answer:
28.5 feet
Step-by-step explanation:
A water tower casts a shadow that is 24 foot long. A 9.5 foot tall tree casts a shadow that is 8 foot long. What is the height of the water tower?
The formula is given as:
Height of the tower/Shadow of the tower = Height of the tree/Shadow of the tree
Let the Height of the tower = x
Hence:
x/24 = 9.5/8
Cross Multiply
8x = 24 × 9.5
x = 24 × 9.5/8
x = 28.5 feet
Therefore, the height of the water tower is 28.5 feet
