2,1
Step-by-step explanation:
Answer:
105
Step-by-step explanation:
Let the complex number be x + iy
Then by the pythagoras therem
17 = x^2 + y^2
D will satisfy this equation
4^2 + (-1)^2 = 17
answer is D 4 - i
Set up a ratio 3 3/4 = 15/4 and 1 1/2 = 3/2 so
((15/4miles) / (3/2hours)) = xmiles/4hours solve for x
so x = 4hours*((15/4miles)/(3/2hours)) = x miles
the hours cancel and you are left with x miles = 10miles
9514 1404 393
Answer:
The equation has infinite solutions.
Step-by-step explanation:
When the same expression appears on both sides of the equal sign, the equation has an infinite number of solutions. It is true for all possible values of the variable.
x = x . . . . is true for all values of x
