Answer:
x ≈ -0.90, y ≈ 2.31
x ≈ 1.40, y ≈ 9.19
Step-by-step explanation:
Easiest and fastest way to do this is to graph the systems of equations and trace where the graphs intersect:
V=1/2a*c*h this is to solve the volume of a prism
Answer:
Total sales revenue use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] )
For each of the stores: Use excel function: For Store 1: =sumif(B4:B99,1,I4:I99) then repeat same for Store 2 to store 8
Step-by-step explanation:
To modify the spreadsheet to calculate the total sales revenue we will add a column " sales revenue "
multiply values of column : ( unit sold * unit price ) to get Total sales revenue. then use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] ) to find Total sales revenue
calculate the total revenue for each of the 8 stores using a pivot table using "store identification number" in row and " sales revenue " in values field
To get the sales revenue ; replace " store identification value" with sales region " column
Answer:
None of these.
Step-by-step explanation:
Let's assume we are trying to figure out if (x-6) is a factor. We got the quotient (x^2+6) and the remainder 13 according to the problem. So we know (x-6) is not a factor because the remainder wasn't zero.
Let's assume we are trying to figure out if (x^2+6) is a factor. The quotient is (x-6) and the remainder is 13 according to the problem. So we know (x^2+6) is not a factor because the remainder wasn't zero.
In order for 13 to be a factor of P, all the terms of P must be divisible by 13. That just means you can reduce it to a form that is not a fraction.
If we look at the first term x^3 and we divide it by 13 we get 
we cannot reduce it so it is not a fraction so 13 is not a factor of P
None of these is the right option.
Answer:
(4, 5 )
Step-by-step explanation:
x + y = 9 → (1)
x - y = - 1 → (2)
adding the 2 equations term by term will eliminate y
2x + 0 = 8
2x = 8 ( divide both sides by 2 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
4 + y = 9 ( subtract 4 from both sides )
y = 5
solution is (4, 5 )
