Answer:
The total would be 40.53
Or
Solve for the first variable in one of the equations, then substitute the result into the other equation.
x = 3 − 4
y
Step-by-step explanation:
This question is incomplete so
Answer:
2 real solutions
Step-by-step explanation:
a=-10, b=-4, c=2
(-4)^2-4x(-10)x2=96
Answer:
not necessarily
Step-by-step explanation:
Taking the square root of both sides, you have ...
±a = ±b
Those four cases resolve to two unique cases:
a = ±b
The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.
