Answer:
If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent.
Step-by-step explanation:
Answer:
x =(11-√193)/2=-1.446
x =(11+√193)/2=12.446
Step-by-step explanation:
Answer:
x = 9
y = 9√3 = 15.6
Step-by-step explanation:
The triangle given is a right triangle, therefore:
✔️apply trigonometric ratio formula to find x:
Reference angle = 60°
Hypotenuse = 18
Adjacent = x
Thus:
Cos (60) = x/18
Multiply both sides by 18
18×cos(60) = x
9 = x
x = 9
✔️find y by applying pythagorean theorem:
y² = 18² - x² (pythagorean theorem)
y² = 18² - 9² (substitution)
y² = 243
y = √243
y = √(81*3)
y = 9√3 = 15.6
Answer:
5/6 because 1/2 plus 1/3 is 5/6, meaning that B is the correct answer.
Hope this helps!
