Does the point (0, 0) satisfy the equation y = 9x?
miskamm [114]

Answer:

yes it does

Step-by-step explanation:

because the equation y=9x does not have a y-intercept (all slopes come in the form y=mx+b -- it can be written differently though) and since there is no 'b' that means the y-intercept is 0. So whenever there is no y-intercept, the slope starts at 0.

A large mixing tank currently contains 350 gallons of water, into which 10 pounds of sugar have been mixed. A tap will open, pou
Marysya12 [62]

Answer

Let t be number of minutes since tap is opened

water is increased by 20 gallons of water per minute.

sugar increase rate of 3 pounds per minute

water :- W(t) = 350 + 10 t

sugar :- S(t) = 10 + 3 t

concentration

C(t) = \dfrac{S(t)}{W(t)}

at t = 15 minutes

C(15) = \dfrac{S(15)}{W(15)}

C(15) = \dfrac{10 + 3\times 15 }{350 + 10\times 15}

C(15) = 0.11

at beginning t = 0 minutes

C(0) = \dfrac{S(0)}{W(0)}

C(0) = \dfrac{10 + 3\times 0}{350 + 10\times 0}

C(0) = 0.0286

C(15) > C(0)

hence, concentration is increasing as time is passing.
