3.30 x 5 = 16.50
4.30 x 7 = 30.10
30.10 + 16.50 = $46.60
Answer:
Step-by-step explanation:
so these two lines cross at some point.. and they want to know the y point at which they cross... sooo..
solve them as a system to find the points that are common to both
Eq. 1) 5x -2y = 16
Eq. 2) -4x+6y=-15
i'll use the elimination method as these equations "lend" themselves to that way.. they are easy to solve that way .. in other words..
multiply Eq. 1 by 3 the add Eq. 2 .. to it... add the terms as columns....
15x-6y = 48
<u> + ( -4x+6y=-15)</u>
= 11x+ 0y =33
x=3
nice, now plug 3 in for x in one of the Eq. try Eq. 1
5(3)-2y=16
15-2y=16
-2y =1
y = 
since we're looking for the y coordinate... that's your answer 
Answer:
$2479.02
Step-by-step explanation:
The invested amount is $2000 at a rate of 2.4% which compounds semiannually.
Therefore, the semiannual interest rate is
%.
Then the principal is compounded (9 × 2) = 18 times within a period of 9 years.
If there is no withdrawal from the account, then after 9 years the sum will become
