I don’t know what answer to put for increasing and decreasing.

Increasing: (2, ∞) Decreasing: (-∞,2)

Step-by-step explanation:

Think of the parabola (just for visualization purposes) as the direction of a rubber ball being thrown from above. The ball starts to decrease in position, eventually hitting the ground, and then starts to increase back to the orginal height and beyond.

So, because parabolas extend infinitely in both the positive and negative direction, we can use intervals to express the parts of the graph where it increases and decreased.

The minimum value point, or vertex is the point where the parabola changes direction. The vertex is visibly at (2,-4). So, the interval for decreasing would be (-∞,2) and increasing would be (2,∞)

Note: We use the symbol "[" to indicate that a value is included in the interval.

Because infinity is a concept and not a number, we have to use the non-inclusive version of it: "(" (simple parentheses) to indicate that infinity is NOT included in the interval, but it simply keeps extending in both directions.

I hope this helps you out.

Find the constant of proportionality (unit rate) for each set of valuesprofit per shirt sold
shirts: 5 10 15
profit: $7.50$15.00 22.50

$1.50 Step-by-step explanation: To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt. 7.50 / 5 =$1.50

15 / 10 = $1.50 22.50 / 15 =$1.50

Best of Luck!

Step-by-step explanation:

7.50/5 = 1.5

15/10 = 1.5

22.50/15 = 1.5

40 deg

Step-by-step explanation:

The vertical sides of the rectangle are parallel, so the triangle is a right triangle.

The triangle is a right triangle, so the acute angles are complementary.

The bottom right angle of the triangle measures 90 - 50 = 40 deg.

The bottom line and the top side of the rectangle are parallel, so corresponding angles are congruent. x and the 40-deg angle are corresponding angles, so they are congruent.

x = 40 deg.
