1. 75,(9)09,931 rounded to the nearest hundred-thousand, 9 is the target, the one with the () on it. Aka the number place your rounding too 2. 104,988 rounded to the nearest hundred, 9 is the target

3. 19,9(9)5 rounded to the nearest ten, nine is the target

75,900,000

Step-by-step explanation:

75,900,000 because 0 is less than 5

105,000 because 8 is greater than 5 and number is 9 so 1 more than 9 is 10

20,000 is the nearest tenth because 5 and up round up

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
