Which statement is true about parallelograms?

Congruent - The same

• A parallelogram reflected across one of its diagonals is always carried onto itself

• A parallelogram reflected across a line segment joining the midpoints of its opposite sides is carried onto itself.

• A parallelogram reflected across one of its diagonals is carried onto itself if its adjacent sides are congruent.

• A parallelogram reflected across a line segment joining the midpoints of its opposite sides is carried onto itself if its opposite sides are congruent

John has four more nickels than dimes in his pocket, for a total of $1.25. Which equation could be used to determine the number of dimes, x, in his pocket?

• 0.10(x + 4) + 0.05(x) = $1.25

• 0.05(x + 4) + 0.10(x) = $1.25

• 0.10(4x) + 0.05(x) = $1.25

• 0.05(4x) = 0.10(x) = $1.25

Answer explanation

Since there are 4 more nickels, we know that x must represent the dimes, and x + 4 represents the nickels. Each dime is worth 0.10 cents, and each nickel is worth 0.05 cents.

The cost of a business is the amount of money spent to start the business and keep it in operation. The revenue is the amount of money the business earns from sales of goods or services.

An online business called Muffins A-plenty started on January 1 of a recent year. The lines in the graph below represent the cost function and the revenue function of the first six months that Muffins A-plenty has been in operation.

Part A

Write equations to represent the cost function for this business.

Answer explanation

Correct answer: y = .5x + 3.5

The y intercept is at 3.5. The slope goes up by 3 and over by 6. 3/6 = .5

Part A

Write equations to represent the revenue function for this business.

Answer explanation

Answer: y = 1.3x

The y intercept is at 0. The slope goes up 8 and over 6, so the slope is 8/6 or 1.3
