Answer: Y = - 4 & x = 1
Step-by-step explanation:
Systems of linear equations: We will solve this using substitution but you can use 2 more ways.
7x + 2y = -1
2x - 4y = 19
Leave X alone first: -------------------
10x - 2y = 18
10x/10 = 18 + 2y/10
x = 9/5 + y/5
Solve for y:
7(9/5 + y/5) + 2y = -1
63/5 + 7y/5 + 2y - 1
63/5 + 7y/5 = 10y/5 = -1
63/5 + 17y/5 = -1 (-5/5)
17y/5 = -68/5 (cancel the 5)
y = -68/17
y = - 4 (Your Answer)
7x + 2(- 4) = -1
7x + (-8) = -1
7x = 7
x = 1
CHECK=
7(1) + 2(-4) = -1
7+ (-8) = -1.
-1=-1
Answer:
Answer for the question:
To compute a19 mod N, the modular exponential algorithms that we studied would do 8 modular multiplications (5 squarings and 3 multiplications by a). What is the minimum number of modular multiplications needed to compute a19 mod N if you are free to use any sequence of modular multiplications.)
is given in the attachment.
Step-by-step explanation:
C.)
f=(9/5)c+32
f-32=(9/5)c
(f-32)/(9/5)=c
(f-32)(5/9)=c
Answer:
D sh.225000
Step-by-step explanation:
Calculation to determine UNESS fixed expense?
Using this formula
Fixed expense=(Total sales - Operating income)*Contribution margin ratio
Let plug in the formula
Fixed expense=($1,000,000-$100,000)*0.25
Fixed expense=$900,000*0.25
Fixed expense=$225,000
Therefore UNESS fixed expense is $225,000
