For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.

I need help please thanks

strojnjashka [21]

Answer:

y = 1/2x + 0

You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.

There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help

Complete all 3 questions.

Answer:

1.x^2-5x

2.2x^2+15x+18

3. x^2+20x+18

Step-by-step explanation:

1. x(x-5) x*x-5*x = x^2-5x

2. (x+6)(2x+3) x*2x+x*3+6*2x+6*3= 2x^2+15x+18

3.(2x^2+15x+18)-(x^2-5x)=x^2+20x+18

If F= - 1 - 9 , G= 7 - 9 , and d=3, what is dF+G?

olga2289 [7]

Hello! -1 - 9 is -10. F = -10. 7 - 9 is -2. G = -2.

F = -10
G = -2
d = 3

Okay, so because d and F are beside each other, we multiply both of the values. Let's plug in the values. -10 * 3 is -30. This is because one negative and one postive make a negative number. Now, we add the number. Because it is negative, we have to go into the negatives more. -30 + (-2) is -32. There. The answer is -32.
