Answer:
0.75
Step-by-step explanation:
cost/lbs. = $3.75/5lbs = 0.75/1lb
Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
So here is the answer. The rent of the movie from redbox is $1.29 each night, and there is an additional fee of $0.50. So in order for us to know how much it would cost for 3 nights, we are going it to put this way. N = 0.50 + 3(1.29). And this would give us the answer of $4.37. This is the cost for 3 nights only. For 10 nights, it would be N = 0.50 + 10(1.29) and it would be $13.4. Hope this helps.
Answer:
The value of k=4
Step-by-step explanation:
we have
f(x)=0.4x
This function represent a linear direct variation (The line passes through the origin)
we know that
If f(x) is shifting up by 4 units
then
The y-intercept of the function will be the point (0,4)
therefore
The function g(x) will be -----> g(x)=0.4x+4 (equation of the line into slope intercept form)
The rule of the translation
f(x) --------> g(x)
(x,y) -------> (x,y+4)
The translation is 4 units up
therefore
The value of k=4
