first u should find the area of rectangular:

7 × 16 = 112

then u should find the area of triangular:

Altitude = 13- 7 = 6

base=16 - 8 = 8

so...u can find the area of triangular now:

(6× 8)÷2 = 48 ÷ 2 = 24

so...the area of your shape is: 112+ 24 = 136

x+y=10

x+2y=14
x is common in both so u have to subtract the second one from 1st
x-x + y-2y = 10-14
-y = -4
y=4
which means bottle of water (y) = 4
and then substitute 4 in equation (x+y=10 or x+2y=10)
x + 4 = 10
x=6

The graph shows the level of ibuprofen, y units, in a patient’s bloodstream x hours after the ibuprofen was taken. Select the co

ElenaW [278]

The graph is missing, so i have attached it.

Answer:

From 0 hours to 2 hours.

Step-by-step explanation:

From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.

Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.

After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.

Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.

Which of the following sets represents a function?

Llana [10]

Step-by-step Answer:

Whenever two relations that has identical values in the independent variable, i.e. x, or the first variable, but having a different value for the dependent variable, it is NOT a function.

For example, {(5,4),(5,6),(2,3)} is NOT a function because the identical values of the independent variable "5" do not correspond to the same value of the dependent variable.

In other words, when we are given an input of 5, we do not know if the output is 4 or 6, so it is NOT a function.

If the output is defined whenever we are given a valid input, it is a function.

For the given examples,

{(3,5),(-1,7),(3,9)} => NOT a function because when given an input of "3", we cannot determine output.

{(1,2),(3,2),(5,7)} => IS a function, because when we are given any of the valid inputs (1, 3, or 5), we have a unique output.

Similarly the first one,

{(1,2),(1,4),(1,6)} => NOT a function, because we cannot determine a unique output when given an input of "1".
