First you multiply
so you will get 6n+6= 18n+29
Then move all "n" on one side of the equation
-23=12n
then divide by 12
the answer should be
n= -1.916
Answer:
The solution is (2, 1).
All other ordered pairs do not work.
Step-by-step explanation:
-2x + 5y = 1
5x - 3y = 7
-10x + 25y = 5
10x - 6y = 14
19y = 19
y = 1
5x - 3(1) = 7
5x = 10
x = 2
(2, 1)
The solution is (2, 1).
All other ordered pairs do not work.

Answer:
x<_ -8
Step-by-step explanation:
add 16 to -24
Let f(x) = sqrt(x). Use linear approximation about x = 25, since 24 is close to 25, and since it is easy to take the square root of 25.
Note that f ' (x) = 1/[2sqrt(x)] from the power rule.
About x = 25, f(x) is approximately f(25) + f ' (25)(x - 25).
So sqrt(24) = f(24) is approximately
f(25) + f ' (25)(24 - 25) = sqrt(25) + {1/[2sqrt(25)]}(-1) = 5 - 1/10 = 4.9 .
