Quickly will give brainliest answer xz is a common external tangent to circles w and y. what is the distance between the two centers of the circles? round to the nearest hundredth.

Construct a triangle by drawing a line parallel to XZ at Center W; intersecting the radius from Center Y to Z.

It is a right-angled triangle with one side at the same length as XZ = 42.

Length of the other side of the right-angle is the difference in radius = 19-11 = 8

Distance between centers = length of hypothesis

= sqrt(42^2 + 8^2)

= 42.755 = 42.76

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
