There both types of numbers but a whole number is a number with no exponents or decimals, but decimals are like a broken un half whole number
The pool is drained at 700 gallon per hour , so you need to multiply the number of hours ( t) by 700 to find the total number of gallons after a certain amount of hours, this would be written as 700t.
You would then need to subtract that amount from the starting value of 28,000.
This would make the equation g = 28,000 - 700t.
Answer:
y = -3x + 7
Step-by-step explanation:
Using the equation of line
y = mx + C
y - y_1 = m(x - x_1)
First find the slope
With eqn y = 1/3x - 3
Note, if two lines are perpendicular, their slope will be negative reciprocal
slope = m = -3/1
Using y - y_1 = m(x - x_1)
With point ( 3, -2)
x_1 = 3
y_1 = -2
y - (-2) = -3/1(x - 3)
y + 2 = -3/1(x -3)
Open bracket
y + 2 = -3(x - 3)/1
y + 2 = (-3x +9)/1
y = (-3x + 9 )/1 - 2
LCM is 1
y = -3x + 9 - 2
y = -3x + 7
The equation of the line is
y = -3x + 7
