Solve equation [1] for the variable y
[1] y = -x - 4
Plug this in for variable y in equation [2]
[2] 4x - 4•(-x -4) = 16
[2] 8x = 0
Solve equation [2] for the variable x
[2] 8x = 0
[2] x = 0
By now we know this much :
x = 0
y = -x-4
Use the x value to solve for y
y = -(-0/32766)-4 = -4
Solution :
{x,y} = {0/32766,-4}
{x,y} = {0,-4}
Answer:
Rs. 4266.67(approx) will be paid for gazing 20 cows for 8 weeks.
Explanation:
A shepherd is paid rs. 2400 for gazing 18 cows for 5 weeks .
⇒ Number of money paid for gazing 1 cow for 1 week is, ![\frac{2400}{18\times 5} =\frac{400}{15}= \frac{80}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2400%7D%7B18%5Ctimes%205%7D%20%3D%5Cfrac%7B400%7D%7B15%7D%3D%20%5Cfrac%7B80%7D%7B3%7D)
then,
for gazing 20 cows for 8 weeks is= Rs.
Therefore, the amount paid for gazing 20 cows for 8 weeks is,
or Rs. 4266.67(approx)
Answer 40 nickels, 10 dimes, and 15 quarters.
X + 20 <= √x + 9
x <= √x - 11
This can't be true without using imaginary numbers...
Any number of x greater than 0 will result in a false statement
Any number of x less than 0 will result in an imaginary number because of √x
Step-by-step explanation:
3x=28+y
x=28+y÷3
then puttingx=28+y÷3
3x=14+y
3(28+y÷3)+y=14
84+3y+3y=42
3y+3y=42-84
y=-42÷6
y=7
so putting y=-7
3x-y=28
3x-7=38
x=38+7÷3
x=15
