because i said so
Answer:
B.
Step-by-step explanation:
the visible line is the defined function.
this line goes from x=1 to x=4, and has the functional results from y=1 to y=7.
the domain is the valid interval of the input variable (typically x), while the range is the valid inescapable of the result variable (typically y).
so, B is the right answer.
Answer:
Step-by-step explanation:
Define ...
z = 3x+2
Substitute for that expression in the given quadratic:
z^2 +7z -8 = 0 . . . . . . your equivalent quadratic
_____
This equation is easily solved by factoring:
(z +8)(z -1) = 0
z = -8 or +1
Then x can be found from z:
(z -2)/3 = x
(-8 -2)/3 = x = -10/3
(+1 -2)/3 = x = -1/3
Answer:
$14.93
Step-by-step explanation:
If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.
Total cost=circumference* cost per inch
Circumference of a circle is given by
Where r is radius. Substituting 4.75 inch for r then
Cost=29.86*0.50=$14.93
