Answer:

-2x - 5y

Step-by-step explanation:

-(4x+y)+2(x-3y)

First multiply 2 with (x-3y)

2 × (x-3y) = 2x - 6y

Now find the sum of this with -(4x+y) by adding/subtract like terms

2x - 6y - 4x - y = -2x - 5y

Find the next 3 terms in the geometric sequence -36, 6, -1, 1/6, ...
timama [110]

we are given

geometric sequence -36, 6, -1, 1/6, ...

first term is -36

a_1=-36

now, we can find common ratio

r=\frac{6}{-36}

r=-\frac{1}{6}

now, we can find nth term

a_n=a_1(r)^{n-1}

now, we can plug values

and we get

a_n=36(-\frac{1}{6})^{n-1}

now, we can find 5th term , 6th term, 7th term

fifth term:

a_5=36(-\frac{1}{6})^{4}

a_5=\frac{1}{36}

sixth term:

a_6=36(-\frac{1}{6})^{5}

a_6=-\frac{1}{216}

seventh term:

a_7=36(-\frac{1}{6})^{6}

a_7=\frac{1}{1296}

so, next terms are

a_5=\frac{1}{36} , a_6=-\frac{1}{216}

, a_7=\frac{1}{1296}.............Answer

Find the sum or difference of (2m+7)-(3-4m)
pickupchik [31]
(2m + 7) - (3 - 4m) 

First distribute the (-) in front of the quantity of 3 - 4m. 
Think of it as this: 

-1(3 - 4m) 

You multiply each number inside the parenthesis by -1. 

So: 

3*-1 = -3
-4m * -1 = 4m

Now that you've distributed the negative you can remove the parenthesis. 
Now you'll just set it all up like you would any normal problem. Because -3 is negative you'll make it subtract.... I'll show you what I mean: 

2m + 7 - 3 +  4m 

Combine like terms (Terms which have the same variables... in this case the same number of m's)

Rearranging them can help!

4m + 2m + 7 - 3 

6m + 7 - 3

6m + 4, is our difference!
