8 0

Pick any value in the y column of the table. I'm going to pick 81. Divide the value you picked by the previous y value, which in my case would be 9

Dividing the values gives: 81/9 = 9

So the base is 9. We multiply each y value by 9 to get the next y value
Eg: to go from 1/81 to 1/9, we multiply by 9. Same for 1/9 to 1, and so on.

Answer: Choice B) 9

Note: This trick only works because x is increasing by 1 each time

Solve solve the following equations 2x (x minus 5) close + 3(x-2)=8+7(x-4)

stiv31 [10]

Step-by-step explanation:

2x(x-5)+3(x-2)=8+7(x-4)

2x²-10x+3x-6=8+7x-28(Group like terms)

2x²-10x+3x-7x=8-28+6

2x²-7x-7x=-20+6

2x²-14x=-14(Divide both sides by -14)

2x²-x=1

2x=1

x=½

∠MNP is your answer

Step-by-step explanation:

Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.

Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)

Put them together: ∠MNP is your answer
