Hey there!!
The value of the numbers or the variables in a mod is always positive.
The ultimate value for the above given equation is -5
As the answer is negative, the mod has no solutions.
Hence, the answer is no solutions , option ( b )
Hope my answer helps!
Answer:
z =65
Step-by-step explanation:
10+10 because the sum of their squares is 200, if you choose any other pair, the sum of their squares will be higher.
2y - x = 5
x^2 + y^2 - 25 = 0
x = 2y - 5
(2y-5)^2 + y^2 - 25 = 0
(2y-5)(2y-5) + y^2 - 25 = 0
4y^2 - 20y + 25 + y^2 - 25 = 0
5y^2 - 20y = 0
y = 0 , y = 4
x = 2y - 5 , when y = 0
x = - 5
x = 2y - 5 , when y = 4
x = 8 - 5
x = 3
Answer:
the answer is 71.2
Step-by-step explanation:
4×4=16
6.9×2=13.8
13.8×4=55.2
55.2+16=71.2
