Two exponential functions are shown in the table. A 3-column table has 5 rows. The first column is labeled x with entries 2, 1,

0, negative 1, negative 2. The second column is labeled f (x) = 2 Superscript x Baseline with entries 4, 2, 1, one-half, one-fourth. The third column is labeled g (x) = (one-half) superscript x Baseline with entries one-fourth, one-half, 1, 2, 4. Which conclusion about f(x) and g(x) can be drawn from the table? The functions f(x) and g(x) are reflections over the x-axis. The functions f(x) and g(x) are reflections over the y-axis. The function f(x) is a decreasing function, and g(x) is an increasing function. The function f(x) has a greater initial value than g(x).

Answer:

B. The functions f(x) and g(x) are reflections over the y-axis.

Step-by-step explanation:

From the information given the table appears as;

x            f(x)=2^x              g(x)=0.5^x

2               4                            0.25

1                 2                           0.5

0                1                             1

-1                0.5                         2

-2               0.25                       4

Plotting the two graphs to view the trends;

In the graph of f(x)=2^x against x you notice a curve with increasing positive slope.

In the graph of g(x)=0.5^x against x you notice a curve with a negative slope that is increasing.

In combining both graphs you notice that f(x) and g(x) are reflections over the y-axis.

Correct answer is ;The functions f(x) and g(x) are reflections over the y-axis.

How do you work out 3x-2(x+4)=22?
Olenka [21]

Answer:

x=30

Step-by-step explanation:

To solve this equation, simplify using the distributive property and combining like terms. Then solve for x through inverse operations.

3x-2(x+4)=22

3x-2x-8=22

x-8=22

x-8+8=22+8

x=30

What is the measure of the missing angle?!
qwelly [4]

Your answer would be 42 degrees.

To solve this, first look at the information we're given. We know that the shape the missing angle is part of is a triangle, so therefore, the sum of the interior angles will always be 180 degrees. There is a right angle inside of the triangle. One of the exterior angles is 132 degrees.

The first thing we can see from this is that the two interior angles which are not right angles must add up to 90 degrees. Since the sum of all the interior angles is 180 degrees, and there is already a 90 degree angle, the other two must add up to 90 degrees.

The next step would then be to find the other interior angle which is not the missing angle. We can do this because of the exterior angle.

A straight line always has a measure of 180 degrees. In this case, we can see that the line the exterior angle is resting on is straight, and the exterior angle + the other interior angle = the line. Therefore, 132 + the other interior angle must equal 180 degrees.

Subtract 132 from both sides, and you get the other interior angle has a measure of 48 degrees.

Now, to take that and figure out the missing angle.

We know that the angle with a measure of 48 degrees and the missing angle must add up to 90 degrees, as stated above.

48 + missing angle = 90

Subtract 48 from both sides, and you get the measurement of the missing angle is 42 degrees.

Good luck!

Answer: second option -300+150+(-50)

Explanation:

She going down, the value is negative. When going up, the value is positive. So when the swimmer swims down 300 feet, the value is negative. Then he goes up 150 ft, which makes the value positive. Finally, he swims down 50 ft, so the valued is negative.
