No, ur friend is not correct
| 3x + 8 | - 9 = -5....u have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides
| 3x + 8 } = -5 + 9
| 3x + 8 | = 4...so that number is not negative anymore
now u can set up ur 2 equations and solve for x...ur 2 equations would be:
3x + 8 = 4 and 3x + 8 = -4...so there will be 2 solutions
** if that -9 would not have been there, then ur friend would have been correct
To answer this question you need to interpret the ratio of the money correctly. We only know Dwayne money, so it's better to solve the ratio which was related to Dwayne. In this case, it was Kendra or Tom.
Dwayne money = $5
Kendra money= 1/10 Dwayne money= 1/10 x $5= $0.5
Juan money= 1/10 Kendra money = 1/10 x $0.5= $0.05
Tom money = 10 x Dwayne money = 10 x $5 = $50
Ruth money = 10 x Tom money = 10 x $50= $500
The intersection is (12,220) so the quantity is 12 and the price is 220
The values of a which make sense to use as described in the task content include the set of 0 and all real numbers greater than zero, while the values of a that don't make sense to use includes the set of real numbers less than zero.
<h3>What are some values which make sense to uses in the evaluation of k(a) and what are some that don't?</h3>
It follows from the task content that the set of values of a which are required to be identified represents the domain of the function k(a) which is evidently, an exponential function.
Consequently, only positive real numbers can be used as the value of a.
