Answer:
7x -1 is correct after combining like terms
Step-by-step explanation:
6+8x-7-x
To simplify algebraic expression we combine like terms
In the given expression
-x or -1x are same
8x and -1x are like terms
6 and -7 are also like terms
8x-1x= 7x
6 - 7 = -1
So 7x -1 is correct after combining like terms
Answer:
Opt. B
Step-by-step explanation:
The key feature is to eval x in a point where |x| is zero, since the vertex of the function is located at that point.
|x|=0 means that y=-4.
Hence the vertex of this point is located at (0,-4)
4 Units down if we compare with the parent function y=|x|
Step-by-step explanation:
Pyramid
1/2 * 12 * 15
6 * 15 = 90
90 * 4 = 360cm
Cube
12 * 12 = 144
144 * 4 = 576cm
576 + 360 =
936 cm² of paint
Answer:
The exponential decay function.
Step-by-step explanation:
The exponential decay function can be used to model the amount of medicine in a person's bloodstream after a certain amount of time. When a drug is administered to a persons bloodstream perhaps through intravenous injections, the exponential decay function measures the initial concentration of the drug and then after a time t, it notes the new concentration. To obtain the result, the equation below is used:
C(t)=C(0)e^(-kt)
where,
k= constant
C(0)= Initial concentration after the injection
C(t)= Concentration after time t
The third one: No, yes, no
