Answer:
c
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
( leg of the large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × ( 3 + 8) = 3 × 11 = 33 ( take the square root of both sides )
x =
→ c
The answer is B. In 10 hours, the phone would completely lose its charge.
Y=-10(10)+100=-100+100=0
the answer is the first one
Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).
