Answer:
X=-3y/2 + 7/2
y=-2x/3+ 7/3
Step-by-step explanation:
Isolate the variables by dividing each side by factors that don't contain the variable. (solving for x)
Divide each term by −3 and simplify. (solving for y)
You didn't say which one you wanted solve but hope this helps.
117.69615 is correct. it would be 118 to the nearest whole number
Answer:
4x+2h
Step-by-step explanation:
The average rate of change of a continuous function,
f
(
x
)
, on a closed interval
[
a
,
b
]
is given by
f
(
b
)
−
f
(
a
)
b
−
a
So the average rate of change of the function
f
(
x
)
=

(

=

(

Which is the required answer.
Additional Notes:
Note that this question is steered towards deriving the derivative
f
'
(
x
)
from first principles, as the definition of the derivative is:
f
'
(
x
)
=
lim
h
→
0
f
(
x
+
h
)
−
f
(
x
)
h
This is the function we had in [1], so as we take the limit as
h
→
0
we get the derivative
f
'
(
x
)
for any
x
, This:
f
'
(
x
)
=
lim
h
→
0

The answer for your question is 11c. The reason why it's actually 11c is because 12c - c equals 11c.
Hope this helps:)
<span>x in (-oo:+oo)
(8/9)*x = (4/9)*x+8 // - (4/9)*x+8
(8/9)*x-((4/9)*x)-8 = 0
(8/9)*x+(-4/9)*x-8 = 0
4/9*x-8 = 0 // + 8
4/9*x = 8 // : 4/9
x = 8/4/9
x = 18
x = 18
