Well you can add to find out that 9 x 5 = 45 and 1/2 x 5 = 2 1/2 so the correct answer is 47 1/2 to estimate it just do 9 x 5 = 45 Hope this helps! :D

What I would do is to times 9 x 5 = 45

Then, I would times 1/2 x 5 = 2 1/2

Then 45 + 2 1/2 = 47 1/2

You can use estimation by multiplying 9 and 1/2 by 5 and adding their answers to get your answer. Happy to help! c:

Which point lies on the circle represented by the equation (x+5) + (y-9) = 8
olga_2 [115]

Answer:

(-5,9+√8)

Step-by-step explanation:

There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.

the general equation of a circle is:

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

with center at (h,k)

you have the following equation:

(x+5)^2+(y-9)^2=8\\\\h=-5\\\\k=9\\\\r=\sqrt{8}

Then, the center is (-5,9)

if you sum the value of the radius in one of the fourth directions (up, down, left, right), for example upward you have

(-5,9+r)=(-5,9+\sqrt{8})

Then, one point that lies in the circle is (-5,9+√8)

Multiply 320 by 3/5 (.6) and you will get 192. Then you subtract 320 by 47 and get 316. You subtract 192 from 316 and get 124.
