Could someone at least help me on this one? Will give brainiest. Don’t just give me the answer but give me an explanation along with that

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

b. b < 1 might be the correct answer

i'm guessing it could be 4 or 1 but i think it's 4

the distance between the center and any point on the circle is radius. double that and you get the diameter since diameter is doubled radius.

by distane formula, the radius is

sqrt( (x2-x1)^2 + (y2-y1)^2 ) = sqrt( (3-7)^2 + (-2 -1)^2) = sqrt(25) = 5

the diamter is 10
