Answer:
x=-15, y=25. (-15, 25).
Step-by-step explanation:
2x+3y=45
x+y=10
--------------
x=10-y
2(10-y)+3y=45
20-2y+3y=45
20+y=45
y=45-20
y=25
x+25=10
x=10-25
x=-15
Answer:
no
Step-by-step explanation:
Answer: C
y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.
Any questions please feel free to ask. Thanks
Step-by-step explanation:
!
When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :
✰ 
?
We simply derived the formula from Loss = CP - SP.
First , Swap the sides of the equation :
⟶ 
Move SP to right hand side and change it's sign :
⟶
This is how , CP can be obtained when we are given loss and SP.
