1. 1/9
2. 0
3. -9
4. -1
Reasoning: To get the opposite of a number just add a negative sign or take it away. This can be done to all numbers other than 0
Hello!
We can go through the choices and see if they are true
Choice 1
A function has one output for every input
This is not a function because it has -1 as an output for both 4 and -1
This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's
We see that the inputs are -1, 0, 3, and 4
This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's
We see the outputs are -2, -1, and 1
This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are
(-1, 1), (0, -2), (3, 1), (4, -1)
This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer
The answer is A) The diagram represents a function
------------------------------------------------------------------------------------------------------
Hope this helps!
<u>Given</u>:
The measure of ∠ABD is (4x + 15)°
The measure of ∠DBC is (13x + 7)°
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property that every angle in a rectangle is 90°
Hence, the value of x can be determined by adding the two angles and equating to 90°
Thus, we have;
Substituting the values, we have;
Thus, the value of x is 4.
Answer:
Customer has bought too much sand
Step-by-step explanation:
Given that the dimensions (Length, Width and Height) of rectangular box are = 6,5, 1.2.
Volume of a rectangular box = Length * Width * Height
=> 6*5*1.2
=> 36 cubic feet
As mentioned, customer bought a sand box and <u>40 cubic feet of sand.</u>
So,
Volume of rectangular box (R) = 36 cubic feet
Volume of Sand (S) = 40 cubic feet
From analysis
S > R
Which shows that the capacity of sandbox is 36 cubic feet and volume is 40 feet that is a little greater than desired capacity.
Therefore, customer has bought too much sand.
