Answer:
The students spent 135 minutes in lecture and 115 minutes in a lab.
Step-by-step explanation:
Let x and y be the respective amount of time students spent in lecture and lab.
x-20=y --- eqn 1
x+y=250 --- eqn 2
From eqn 1, x=y+20 --- eqn 3
Sub eqn 3 into eqn 2:
y+20+y=250
2y=230
y=115
Sub y=115 into eqn 3:
x=115+20
=135
∴x=135, y=115
Step-by-step explanation:
(a+b)(ab)
The point (2, 5) is not on the curve; probably you meant to say (2, -5)?
Consider an arbitrary point Q on the curve to the right of P, 
, where 
. The slope of the secant line through P and Q is given by the difference quotient,
where we are allowed to simplify because 
.
Then the equation of the secant line is
Taking the limit as 
, we have
so the slope of the line tangent to the curve at P as slope 2.
- - -
We can verify this with differentiation. Taking the derivative, we get
and at 
, we get a slope of 
, as expected.

im think the bowl weighs 49.5 grams by itself
Step-by-step explanation:
405/2= 202.5
765/5=153
202.5-153=49.5
