Answer:

C) decreasing when x > –1

Step-by-step explanation:

To determine whether a function is increasing or decreasing, or whether it increases or decreases in an interval, you must look at the function or the interval from left to right.

Start at the left and move to the right. You see that the function (the y-coordinate of each point) is increasing from an v value of negative infinity till x = -1. At x = -1 the function reaches a maximum point. Now start at x = -1 and, moving to the right, the value of the function (the y-coordinate of each point) decreases.

The correct answer is C) decreasing when x > –1

The diagram shows a sketch of John's yard. He wants to plant grass, so he must calculate the area of the yard. The distance from
Arturiano [62]

The area of the yard is 50,600 square feet.

Option: C.

<u>Step-by-step explanation:</u>

The given information forms a trapezoid.

The AB is the upper base (a) and its length is 200 feet.

The CD is the lower base (b) and its length is 260 feet.

A straight line distance from AB and CD is the height (h) and its measures as 220 feet.

The area of trapezoid A= \frac{a+b}{2} (h).

A= \frac{200+260}{2} (220).

=\frac{460}{2}(220).

=230(220).

=50600 ft^2.

Thus the area of John's yard is 50,600 square feet.

Triangle ABC is graphed below with vertices at A (-4,5), B (-6, -4) and C (4,-4). Use the following rule to produce
guapka [62]

Step-by-step explanation:

A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)

B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)

C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)

Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).
