Answer:
3rd option
Step-by-step explanation:
The absolute value function always gives a positive value , that is
| - a | = | a | = a
Then
| - 3.5 | = 3.5 and | - 3 | = 3
and 3.5 > 3
That is | - 3.5 | > | - 3 |
Answer:
2.1 hours (2 hours and 6 minutes)
Step-by-step explanation:
The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be
⅓+1/7=(7+3)/21=10/21
The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours
0.1 of an hour is equivalent to 0.1*60=6 minutes
Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes
Answer:
x = 3
Step-by-step explanation:
The standard form of a parabola (x^2 function) is:
If we algebraically manipulate this, we can have the vertex form:
Where
x = h will be the axis of symmetry
k will be the vertical shift
(h,k) would be the vertex
Now, the function given in this problem is given in vertex form:
From the original vertex form, we can say that this equation has the folllowing variable values:
a = 1
(3,4) is the vertex
x = 3 is the axis of symmetry
4 is the vertical shift
We are concerned with axis of symmetry. Thus, we can see that
x = 3 is the axis of symmetry
