Front

What is the equation that describes the total cost (y) of a delivery order of cupcakes, given a delivery fee of $10.95 and each cupcake costs $1.15?

Back

y = 1.15x + 10.95, where x is the number of cupcakes.

Front

What does the inequality x ≥ -4 represent on a number line?

Back

It represents all values of x that are greater than or equal to -4.

Front

If Sandy has at least 2 times as many pencils as David, and David has 3 more pencils than Pietro, who has 4 pencils, how many pencils does Sandy have?

Back

Sandy has at least 14 pencils.

Front

What is the minimum number of new baseballs that can be purchased if the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum?

Back

Front

What is the greatest common factor (GCF) of x^3y^k and x^2ky^4 if the GCF is x^3y^3?

Back

The value of k is 3.

Front

Define the term 'Inequality' in mathematics.

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

What is the formula for calculating the total cost (y) of an order that includes a fixed delivery fee and a variable cost per item?

Back

y = mx + b, where m is the cost per item, x is the number of items, and b is the fixed delivery fee.

Front

What does the term 'Greatest Common Factor (GCF)' mean?

Back

The GCF of two or more numbers is the largest number that divides all of them without leaving a remainder.

Front

How do you represent a number line for the inequality x < -4?

Back

Shade the line to the left of -4, indicating all numbers less than -4.

Front

What is the relationship between the variables in the equation y = 1.15x + 10.95?

Back

y increases linearly with x, with a slope of 1.15 and a y-intercept of 10.95.
