Any tangent line to
at a point
will have slope
. Such a line has equation
For this (these) line(s) to pass through (2, -3), you must have
So the two lines in questions are
for these values of
.
To show there is no tangent line that passes through (2, 7), you have to show there is no solution for
in
You have
but this has no real solutions, so no such tangent line exists.
Answer:
The answer is BCE DCE and DCB
Step-by-step explanation:
First change the 230 grams to kilograms or 1 kilogram to grams.
The units have to be the same.
Next set up a proportion.
Cross multiply to solve the proportion.
1 kg = 1000g
230 g/30 biscuits = 1000g/x biscuits
230x = 30(1000)
230x = 30000
divide both sides by 230
x =130 biscuits
