Answer:
a. 7(2g + 20t –3)
b. 14g + 140t – 21
Step-by-step explanation:
a. The first expression 7(2g + 20t – 3)
Stacey and her six friends implies that we have 7 members in the group.
Therefore, the expression above implies that each member of the group has to pay for two rounds of golf and 20 tokens will be discounted $3.00.
The expression (2g + 20t –3) represents the quantity of cost of each friend and this is multiplied by 7 to obtain this first expression, i.e. 7(2g + 20t –3).
b. The second expression 14g + 140t – 21
The simple interpretation of this expression us that deducting $21 from the to total bill which is 14 games of golf plus 140 tokens is equal to the total amount this group spent.
Therefore, this second expression is obtained by simply opening the bracket in the first expression by multiplying 7 by each of the what is in the bracket.
Answer: the blue rectangle one, the second green one or the pink one. hard to decide between the last two. good luck!
Step-by-step explanation:
learned in 2nd grade
<span>dy/dx=xy/3, y > 0 can be rewritten in terms of only one variable (x or y) each:
3 dy
----- = x*dx (first term is all in y; second term all in x).
y
x^2
Integrating, 3 ln y = ------- + ln C, Then ln y^3 = (1/2)x^2 + ln C.
2
Combining the log terms:
ln y^3-ln C = (1/2)x^2.
Given: if x=0, y=4. Subst. these v alues into the equation in y given above:
4^3
ln 4^3 - ln C = (1/2)(0)^2 = 0. Then ln ------- = 0, which tells us that
C
4^3 = C. Thus, the solution is </span>ln y^3 = (1/2)x^2 + ln (4/3).
There are other ways in which you could write this same expression. You could, for example, solve for either y^3 or y alone.
