Answer:
Option A is the correct answer.
Explanation:
There are 6 packages that store 30 baseball cards.
Number of cards in 1 package = 30/6 = 5
Let us consider a as number of packages and b as number of cards.
We have equation for number of cards,
b = 5 a
The constant of proportionality = 5
Option A is the correct answer.
Answer:
Ways of solving it
Step-by-step explanation:
20x - 5x = 65 - 5
as the numbers cross over the equality sign, their positive changes to negative and vice versa
15x = 60
Divide both side by the coefficient of X which is the number Infront of X
15x/15 = 60/15
X=4
OR
20x + 5 = 5x + 65
Dividing through by 5. All the numbers above are divisible by 5. 5 is also the LCM
4x + 1 = X + 13
4x - X = 13 - 1
3X = 12
X = 4
0.(8-0.2w)=-4
W=90
hope this helps! :)
Y=x^2+4
dy/dx=2x
d2y/dx2=2
So the vertex is at an absolute minimum at (0,4)
