A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situati

rewona [7]

Answer:

Number of roast beef sandwiches bought = 5

Step-by-step explanation:

Cost of a roast beef sandwich = $6.75

x = number of roast beef sandwiches bought

Amount Used for Payment = $50

Change Received = $16.25

Actual amount paid = Amount Used for Payment - Change Received

= $50 - $16.25

= $33.75

Actual amount paid = $33.75

Number of roast beef sandwiches bought = Actual amount paid / Cost of a roast beef sandwich

= $33.75 / $6.75

= 5 roast beef sandwiches

Number of roast beef sandwiches bought = 5

Which linear inequality represents the solution set graphed?

postnew [5]

Answer:

Correct option is C

Step-by-step explanation:

First, find the equation of the boundary line. This line passes through the points (0,-3) and (-2,1). Then it has equation

$\dfrac{x-0}{-2-0}=\dfrac{y+3}{1+3},\\ \\4x=-2(y+3),\\ \\y=-2x-3.$

In the attached diagram this boundary line is solid, then the sign of the inequality should be with "or equal to" notion (≤ or ≥). Thus, options A and B are false.

The line divides the coordinate plane into two parts and you have to determine which part to choose. The origin does not lie in the shaded region, then its coordinates cannot satisfy the inequality. Check options C and D.

$0\le -2\cdot 0-3\ (0\le -3)$ - origin does not satisfy (option C is correct);
