5x + 2y = 22
10x + 9y = 59
so now we need to either eliminate the y or the x and we need to multiply both numbers by something so that they will be the same and we can add or minus them.
so here I will eliminate x because it's easier
we multiply the top equation by 2 and the bottom equation by 1 and we get
10x + 4y = 44
10x + 9y = 59
so now we can see that the number of x's are the same and we can just find the DIFFERENCE between the two equations if it was -10x and 10x we would ADD
= 5y = 15
notice that the x'a have cancelled each other out
now we divide both sides by 5 so
y=3
now we have y, we need to substitute it into one of the original equations, doesn't matter which one. I'm going to do the first one.
5x + 2y = 22
5x + 2(3)=22
5x + 6 = 22
now minus 6 from both sides
5x = 16
divide both sides by 5
x = 3.2
we have our answers but to be sure we need to just substitute the values for x and y into BOTH original equations.
5x + 2y = 22
= 16 + 6 = 22
10x + 9y = 59
= 32 + 27 =59
Tadaa!! and there you have it
y = 3
x = 3.2
hope this helped :)
It looks like you're just going to add everything up...

Answer:
An approximate match
Step-by-step explanation:
The vlookup (vertical lookup) function is a search function in excel used in locating values in an excel table.
The vlookup syntax is written as:
=VLOOKUP(value, table, col_index, [range_lookup])
The range_lookup is an optional parameter which is used to indicate if the search should be for an exact match or approximate match. Since a column, resort fee will be used as a possible additional cost; the search would be required to return an approximate search rather than an exact match in other for the search condition to be adequately implemented.

Answer:
3 units left
Step-by-step explanation:
Replacing x in a function with (x-h) translates the graph to the right by h units. Here, you have h = -3, so the graph is translated left 3 units.
