Answer:
Lana's sister is six.
Step-by-step explanation:
12/2= 6
Lana is two times her sisters age, so you have to divide Lana's age by two.
Answer:
Step-by-step explanation:
<u>Given functions f(x) and g(x). f(x) is:</u>
<u>Converted into vertex form, it is:</u>
<u>g(x) has vertex at (-2, -14), it's vertex form is:</u>
Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).
Both have positive leading factors, therefore the vertex is their minimum point.
Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.
Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.
Correct choice is A
1 pound water bottle = 453.59 ml of water.
I would say all of them can be model as functions.
<span>model number:
This would be a onto function, meaning that the outputs are not unique.
f(model_1) = f(model_2) = computer_type.
</span><span>part number:
</span>This would mean the function takes in multiple parameters.
f(part_1, part_2, part_3, ...) = computer
<span>serial number:
This is the most obvious one; an one-to-one function:
f(s_num_1) = computer_1;
f(s_num_2) = computer_2;</span>
Write it out as an equation:
11+(-1/.3333)=x
x=-3
