It is profitible as long as your roll is above 7 which is rather easy to get
Answer:
The answer is B.) 3
Step-by-step explanation:
y = 2x -5
y= -3x + 1
Here both the equations are in y = mx + b
where m is the slope and b is the y intercept
y =2x -5, the slope = 2 and b intercept = -5
y= -3x + 1, the slope = -3 and b intercept = +1
Both the equations have different slope. So there should be a single solution
Yes, the system of equations have a solution
Answer: (2, -5) (light blue answer choice)
Solving by substitution
−7x+y=−19;−2x+3y=−19
−7x+y+7x=−19+7x (Add 7x to both sides)
y=7x−19
Step: Substitute7x−19 for y in −2x+3y=−19:
−2x+3y=−19
−2x+3(7x−19)=−19
19x−57=−19 (Simplify both sides of the equation)
19x−57+57=−19+57 (Add 57 to both sides)
19x=38
19x/19 = 38/19 (Divide both sides by 19)
x=2
Step: Substitute 2 for x in y=7x−19:
y=7x−19
y=(7)(2)−19
y= −5 (Simplify both sides of the equation)
Therefore: x = 2 and y = −5
