i got 42, multiply 12 by 3. then add 6. 42 minutes
Answer: -9x + y
To do this problem, we must combine like terms. This means combining any terms that have the same variable at the end.
(-2x - 7x) + (5y - 4y) = -9x + y
Answer:
108
Step-by-step explanation:
Limit as x approaches 9 of x^2 -81/sqrt of x - 3
First substitute x into the expression
= 9²-81/√9 - 3
= 81-81/3-3
= 0/0 (indeterminate)
Apply l'hospital rule
= lim x -> 9 d/dx(x²-81)/√x - 3
= lim x -> 9 2x/1/2√x
Substitute x = 9
= 2(9)/1/2√9
=18/1/(2(3)
=18 × 6/1
= 108
Hence the limit of the function is 108
Answer:
8r+9p-7
Step-by-step explanation:
12p-3p=9p
8r+9p-7
Same side interior angles are supplementary, which means together they add up to 180 degrees.
In order to find the value of angle m, subtract 180 from the supplement.
180 - 78 = 102
The value of m is 102 degrees
