Answer:
(-5,8) and (-3,-8)
is
y=-8x-32
Step-by-step explanation:
Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
31.5/1.75= 18
Alice can place 18 cars in a line along the shelf.
Hopefully, this helps!
Answer: False
=============================
Replace every x with -3. Then simplify the left side.
(x-5)(x-7) < 0
(-3-5)(-3-7) < 0
(-8)*(-10) < 0
80 < 0 ... this statement is false, 80 is not smaller than 0
----
(x-5)(x-7) < 0 is false when x = -3
It would take the faucet 18 hours to fill the tank because 18/12=1.5. That means it will be 1.5 times slower to fill the tank up with the hose on. 1.5*12=18.
