Answer:

Step-by-step explanation:

The y-axis shows the number of gallons of water left (with respect to time).

The x-axis shows the time.

Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.

Looking at the choices, that is B, 0 ≤ x ≤ 12

Manny and Susan have an egg carton full of eggs to use for their science project.

Answer:

5/6

Step-by-step explanation:

1/3 + 1/2 is a simple addition fraction problem.

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.

UkoKoshka [18]

Answer:

g = 118°, h = 62°, k = 140°, m = 40°

Step-by-step explanation:

g = 118°

h = 180 - 118 = 62°

k = 140°

m = 180 - 140 = 40°

Drag each interval to a box to show if the function shown is increasing, decreasing, or neither over that interval. 6 4 10 8 1 t

Kitty [74]

Answer:

Function (4 < x < 6) and (8 < x < 10) is decreasing

Function (1 < x < 4) and (6 < x < 8) is increasing

Function (10 < x < 14) is neither increasing nor decreasing

Step-by-step explanation:

The question is incomplete. The complete question has been added as an attachment.

From the graph:

x-axis (horizontal), y-axis (vertical)

Note: moving from negative bigger number to negative smaller number is an increase.

Moving from negative smaller number to negative bigger number is a decrease.

6 < x < 8: on the x-axis, from number +6 to +8, you find on the y-axis the line moved from -7 to -4. That is an increase.

4 < x < 6: on the x-axis, from number +4 to +6, you find on the y-axis the line moved from -3 to -7. That is a decrease.

10 < x < 14: on the x-axis, from number +10 to +14, you find on the y-axis the line moved from -5 to -5. It remained on the same number. It is neither increasing nor decreasing.

8 < x < 10: on the x-axis, from number +8 to +10, you find on the y-axis the line moved from -4 to -5. That is a decrease

1 < x < 4: on the x-axis, from number +1 to +4, you find on the y-axis the line moved from -11 to -3. That is an increase.
