Answer:
Option B) The variable Y will cancel out first.
Step-by-step explanation:
we have
5x-y=-21 ----> equation A
x+y=-3 ----> equation B
Solve by elimination
Adds equation A and equation B
5x-y=-21
x+y=-3
--------------
5x+x=-21-3 ----->variable y will be eliminated first
6x=-24
x=-4
Answer:
x= -15/2 y=-33/2
Step-by-step explanation:
i dont know how you want to solve it but if it is "system of equations" then first solve for the first variable in on e of the equations, then substitute the result into the other equation.
Answer:
f(1) = 1
Step-by-step explanation:
The value of f(1) simply means what is the corresponding output we would get for an input of 1.
This also implies that for what of y is x equal to 1?
From the graph, when x = 1, y = 1.
Thus:
f(1) = 1
Answer:
35/4 or 8,3/4
Step-by-step explanation:
Flip the second fraction and multiply.
Answer:
Total trade discount on 30 boxes = $201.555
Step-by-step explanation:
1 box = $14.93
And a trade discount of 45% is allowed on a single box,
Therefore, the discount on one $14.93 box will be
45% × $14.93 = $6.7185
So, if there are now 30 boxes, the trade discount on all 30 boxes will be
30 × (trade discount on one box) = 30 × ($6.7185) = $201.555
Hope this helps!
