Answer:

Check the 2nd and 3rd answer choices.  See below.

Step-by-step explanation:

Look carefully at the 2nd and 3rd of the given equations.  Note that each of these two can be made identical to 3x + 2y = -12 through multiplication of each by a constant.  Regarding the 2nd answer choice, if we multiply this equation by -1, we obtain 3x + 2y = -12.  Regarding the 3rd answer choice, if we mult. this equation by 5, we get 3x + 2y = -12 again.  

Thus, the 2nd and 3rd answer choice equation have the same solution as does 3x + 2y = -12.

How to solve Question 3(c)?
BARSIC [14]
From your work on parts (a) and (b), you know that
.. r = 3.50
.. s = 140
The composite index of production cost from 2007 to 2009 is 114.2.

(c) If the production cost in 2007 was RM50, then in 2011 it was
.. RM50 * (2009 index) * (2011 index) = RM50 * 1.142 * 1.200 = RM68.52

The number of unread emails in Bryan’s account is 100. This number grows by 15 unread emails a day. The function N(t)=100+15t re
miv72 [106K]

Answer:

205

Step-by-step explanation:

Given

N(t) = 100 + 15t is the equation of the relation.

We're asked to find N(7)

Taking a look at the question again and putting it side by side the equation

N(t)

N(7)

We can deduce that t = 7, and as such, solve for it in the equation given

N(7) = 100 + 15(7)

N(7) = 100 + 105

N(7) = 205

Therefore, the number of unread mails after 7 days will be 205
