Answer:
Step-by-step explanation:
We are given the following in the question:
Perimeter of rectangle = 80 inches.
Let l be the length and w be the width of rectangle.
Perimeter of rectangle =
Putting values, we get,
Now, we have to find the area of the rectangle in terms of w.
Area of rectangle =
Putting values, we get
is the required expression of area of rectangle in terms of w.
Yes, the perimeter is used to calculate the length of the rectangle in the term of w.
milligrams of salt, which is 20%
20
%
of the recommended daily amount.
What is the recommended daily amount of salt?
480 x 5 = 2400. 2400 milligrams of salt is the recommended daily amount.
Answer:
2400 milligrams because 480 is 20% of the recommended amount
Step-by-step explanation:
20*5 = 100% so 480* 5 = 100% or recommended amount

Answer:y=3
Step-by-step explanation:
Answer:(0,5)
Step-by-step explanation:
Y-3=2(x+1)
Rewrite it
2(x+1)=y-3
Sub. 0 for xto find y
2=y-3
Y-3=2
Y=2+3
Y=5
5-3=2(x+1)
2=2x+2
2x+2=2
2x=-2+2
2x= 0
X=0
To check
5-3=2(0+1)
2=2(1)
2= 2
It checks
The graph of the function is attached to the solution.
The given equation is f(x) = x²+5, the power on the variable is 2, that means the equation is a quadratic equation therefore, the graph will be a parabola,
Since, there is no negative sign so, the parabola will be opened up,
Also, there are 5 units added in the equation that mean the parabola will be 5 units up from the origin.
So, the graph will be an upward opened parabola with its vertex at (0, 5)

Answer:
I would say Graph 2 because if its showing f(x)=x2+5
there are no negatives in this equation, so I think it is graph 2
