Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
Answer:
2x^2=3x+2
2x^2-3x-2=0
(x-2)(x+1/2)=0
x=2 or x=-1/2
The sum of 2 solution 2+-1/2=3/2
Step-by-step explanation:
Okay... so we have three places the automobiles can come in.
_ _ _
Now, how many automobiles have a chance of being in first place?
10.
Now, how many automobiles have a chance of being in second place now that the first place slot is taken?
9.
Now, how many automobiles have a chance of being in third place if the first and second place slots are taken by one automobile?
8.
Now multiply the numbers together to find the number of situations.
10 x 9 x 8 = 720.
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
putting time into years for simplicity,
4 months ÷ 12 months/year = 0.333333 years,
then, solving our equation
I = $ 376.00
I = 18800 × 0.06 × 0.333333 = 375.999624
I = $ 376.00
The simple interest accumulated
on a principal of $ 18,800.00
at a rate of 6% per year
for 0.333333 years (4 months) is $ 376.00.
185-7=178
So 178÷185=0.9621621
0.96×100=96%
OR APPROXIMATELY 96 percent
