the distance from the origin is 5, so
sqrt(x²+y²)=5
x²+y²=25
substitue y=x²
y+y²=25
y²+y-25=0
solve using calculator or the formula
to get
y =( -1+sqrt(1+4*25))/2
or y = (-1-sqrt(1+4*25))/2
the second solution is rejected because a square cannot be negative
the value of x is the positive or negative (sqrt... or -sqrt...) or y
Answer:
x ≤ 3
Step-by-step explanation:
divide the four to get x but itself and since the 4 is positive the inequality stays the same.
It could mean a ratio of a number. for example, i could say 30 percent of bag or marbles IS red.
The answer as a decimal: .002
As a fraction: 1/500
Answer:
3/8
Step-by-step explanation:
= (1/4 + 1/2 )/2
= 3/4 ÷ 2
= 3/(4×2)
= 3/8 (final answer)
