You have to put your first dot on -5 on the y-axis and then from that dot go up 3 and right one and put another dot there. Then go from the dot on -5 and go down 3 and left 1 and put another dot. Then connect the dots with the line

Help me solve those show work 3(2a-5)=12-7a, 27=3c-3(6-2c)and 6c-8-2c=-16

Nadusha1986 [10]

1) 3(2a-5)=12-7a

First distribute the 3. This leaves you with 6a-15=12-7a.

Now, add 15 to both sides. This leaves you with 6a=27-7a.

Now, add 7a to both sides. This leaves you with 13a=27.

Now, you can finally divide 13a on both sides. This leaves you with a=27/13

2) 27=3c-3(6-2c)

First, distribute the 3.This leaves you with 27=3c-18+6c

Now, combine like terms/simplify. This leaves you with 27=9c-18.

Now, add 18 to both sides. This leaves you with 45=9c.

Now, you can finally divide 9 on both sides. This leaves you with 5=c.

Lastly, use the reflexive property. This leaves you with c=5.

3) 6c-8-2c=-16

First, combine your like terms. This leaves you with 4c-8=-16.

Now, add 8 to both sides. This leaves you with 4c=-8.

Now, divide 4 on both sides. This leaves you with c=-8/4.

Finally, you can simplify the fraction. This leaves you with c=-2.

Find the 2nd term in the expansion of (a + b)^7 in simplest form

klasskru [66]

Answer:

7a^6b

Step-by-step explanation:

Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b

Note that the power of b in the second term is b^1 which is the same as b

F(x)=x^5-5x^3+4x How do i factor?

wel

Answer:

x(x+2)(x-2)(x+1)(x-1)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula,]a^{2} - b^{2} = (a+b)(a-b), where a = x and b = 2.
