Choice B) As x decreases, y decreasesChoice C) As x increases, y approaches 0Choice F) The function is an increasing function

=====================================================

Explanation:

The graph has a negative y-intercept. So for example, we could have a y intercept of (0,-1) or (0,-2). The x value is always 0, and in this case, the y coordinate is some negative number.

Due to the negative y intercept, this means the function curve is below the x axis at this point. The common ratio r, such that 0 < r < 1, tells us that the exponential function is decreasing in absolute value. Let's say the y intercept was (0,-10) and the common ratio was r = 0.5

The common ratio of r = 0.5 means the second term is r*(first term) = 0.5*(-10) = -5, and the third term is r*(second term) = 0.5*(-5) = -2.5

The terms: -10, -5, -2.5 show us that they are decreasing in absolute value, but in terms of a graph, they are going upward toward zero.

So that's why as x increases, so does y (which makes it an increasing function). And y is approaching y = 0. However, it never actually gets to y = 0.

On the flip side, if x is decreasing, then y is also decreasing. Both x and y increase or decrease together in any increasing function. A decreasing function would have x increase while y decreases, or vice versa, meaning they go in opposite directions.

Enter your answer in the box.
lb of mixed nuts

Answers

Answer:

the pounds of mixed nuts are in a batch altogethe

77÷15.4%

=77÷0.154

=500pounds

Step-by-step explanation:

Answer:

500 lb of mixed nuts

Step-by-step explanation:

Find how many mixed nuts are in a batch by dividing 77 by 0.154

77/0.154

= 500

So, in a batch altogether, there are 500 lb of mixed nuts

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday,
Wednesday, and Friday, she runs 4 laps on a running trail and then runs 6 more miles. On Tuesday and
Sunday, she runs 6 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How
many laps does Lilliana run on Saturday?

Answers

Answer:

7

Step-by-step explanation:

Let's call x the amount of miles that equal a lap.

So on Monday Wednesday and Friday, she runs 4x + 6 miles.

On Tuesday and Sunday she runs 6x + 2 miles.

And the problem says that she runs the same distance every day, so that means that

4x + 6 = 6x + 2

Now we solve that equation:

4x + 6 = 6x + 2

6 = 6x + 2 - 4x

6 - 2 = 6x - 4x

4 = 2x

x = 2

After that we choose either 4x + 6 or 6x + 2 to calculate the distance she runs on per day by replacing the x with a 2.

4(2) + 6 = 14

6(2) + 2 = 14

Finally we just divide the amount of miles (14) by the amount of miles per lap (2).

14/2 = 7 laps

2t - 3 = 1 (solve for t)

we're doing two step equations

Answers

Answer: t = 2

Step-by-step explanation:

2t - 3 = 1

(add 3 to both sides)

2t = 1 + 3

2t = 4

(divide 2 from both sides)

t = 2

the answer is t=2 because if you do 2(2) - 3 it is 1

x = 24

obtuse isosceles triangle

Step-by-step explanation:

x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.

180-132 = 2x

48 = 2x

x = 24

It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.

x=24
