In this problem, it is essential to use the order of operations, or PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction). First, you solve 7-3=4. Then, you multiply 7 times 4, which is 28. Lastly, you add 28 to 156 which is 184. So your answer is B.

Answer:

56 square units

Step-by-step explanation:

I'd recomend using something like "Desmos" to plot the points so then you can see the points and the rectangle. Then count the length and width. For the this rectangle the length was 8 and the width was 7, multiply these and you get the answer of 56 sqaure units.

Answer:

(x, y) = (0, -2248)

Step-by-step explanation:

Substitution

Substitute for y:

300x -2248 = 350x -2248

0 = 50x . . . . . . . . add 2248-300x to both sides

x = 0

y = 300·0 -2248

The solution is (x, y) = (0, -2248).

Elimination

Subtract the first equation from the second.

(y) -(y) = (350x -2248) -(300x -2248)

0 = 50x

x = 0

y = 300·0 -2248

The solution is (x, y) = (0, -2248).

Additional comment

If you think for a bit about what the graph looks like, you realize both lines cross at their y-intercept, (0, -2248). That point of intersection is the solution to the system of equations.
