<u>Answer:</u>
The coefficient of 
<u>Solution:
</u>
The given expression is 
As per binomial theorem, we know,

Now here a = 2x, b = (- 3y) and n = 10 and k = 0,1,2,….10
Now
will be the 6 term where k =5
Now, 
So, the coefficient of
.

The coefficient of 
Answer:
the variable is "b"
Step-by-step explanation:
Answer:
-1
f (x) = -3(x + 5)
Step-by-step explanation:
1) in f(x) = 1/3x-5, replace f(x)= with y= as follows: y = (1/3)x - 5
2) interchange x and y, obtaining: x = (1/3)y - 5
3) solve this result for y: (1/3)y = -x - 5, or -(x + 5). Next, multiply both sides by 3 to eliminate the fraction (1/3): y = -3(x + 5)
4) replace y with the symbol for "inverse of f(x);
-1
f (x) = -3(x + 5)
The sum of two numbers will be zero when you have the same number and one is positive and one is negative. For example 1 + -1= 0
Answer: 7
Step-by-step explanation:
They are alternate interior angle
2x + 5 = 3x -2
2x = 3x -7
-x = -7
x = 7
