This is a linear function in the slope - intercept form:
y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56

answer choice D
Step-by-step explanation:
x => 6 - 4x > 18
= 6-18 > 4x
= - 12 > 4x
= -3 > x
= x < -3
We let x be the number of tablespoon of chemical solution (c) that is to be added to a certain amount of water. The equation that would best represent the given scenario is,
B = 1200 - 75x
Substituting 300 to B of the equation,
300 = 1200 - 75x
The value of x from the equation is 12. Therefore, 12 tablespoon of chemical should be added per gallon. Since there are 500 gallons of water, the amount of chemical that should be added is 6000 tablespoons.
