Answer:
6 3/5 would become 33/5
Step-by-step explanation:
2 + 4 = 6
2/5 + 1/5 = 3/5
6 * 5 = 30
30 + 3 = 33
33/5
-3x+y=5
y=5+3x
Then:
if x=-4; y=5+3(-4)=5-12=-7 This is a possible solution .
if x=3; y=5+3(3)=5+9=14 This is other possible solution.
if x=2; y=5+3(2)=5+6=11, it´s not solution.
if x=1; y=5+3(1)=5+3=8; this is other possible solution.
C. (2,-1)
Answer:
The derivative of the function does not exist.
Step-by-step explanation:
The alternative form of a derivative is given by:
Our function is defined as:
h(x)=|x+8|
i.e. h(x)= -(x+8) when x+8<0
and x+8 when x+8≥0
i.e. h(x)= -x-8 when x<-8
and x+8 when x≥-8
Hence now we find the derivative of the function at c=-8
i.e. we need to find the Left hand derivative (L.H.D.) and Right hand derivative (R.H.D) of the function.
The L.H.D at a point 'a' is calculated as:
Similarly R.H.D is given by:
Now for L.H.D we have to use the function h(x) =-x-8
and for R.H.D. we have to use the function h(x)=x+8
L.H.D.
we have a=-8
=
similarly for R.H.D.
Now as L.H.D≠R.H.D.
Hence, the function is not differentiable.
Hi. When water seeps into the cracks in rocks it expands as it freezes. Once it thaws, it seeps yet again into additional cracks in the rock. Over time, this causes large chunks of the rock to loosen and subsequently fall off.
Hope this helps.
Take care,
Diana
