Two numbers are graphed on the number line below -7 and -3. Consider the inequality t<r. Which values graphed on the number line make the inequality true?
All values of t to the left of r on the number line will make the inequality t < r true. Therefore, any value between -7 and -3 will be a valid solution.
San Jose's elevation is 87 feet. Salton City's elevation is -125 feet. Jackie claims that Salton City's elevation is higher than San Jose's. Which statement explains whether or not Jackie is correct?
Jackie is incorrect.
Although the absolute value of -125 is greater than 87, elevation is measured relative to sea level. In this case, Salton City's elevation is actually lower than San Jose's elevation because it is located below sea level, while San Jose is located above sea level. Therefore, San Jose's elevation is higher than Salton City's elevation.
Brittany graphs the point (6,3) on a coordinate grid. Which describes where she should plot the point if she starts at the origin?
To graph the point (6,3) if starting at the origin, Brittany should measure 6 units to the right along the x-axis, and then measure 3 units up along the y-axis.
Starting from the origin as the reference point, this point will be located in the first quadrant of the coordinate plane.
Charlie's shape has 4 sides and no right angles. The opposite sides are parallel, and some sides have different lengths. What is the best name for Charlie's shape?
The best name for Charlie's shape would be a parallelogram.
A parallelogram is a quadrilateral (4 sides) with opposite sides that are parallel to each other. It is not a right angle, and its sides may have different lengths.
