Find the value of d and YZ if Y is between X and Z.
XY = 11d, YZ = 9d – 2, XZ = 5d + 28

d=2 YZ=16

Step-by-step explanation:

XZ=XY+YZ

5d+28=11d+9d-2

28=11d+9d-2-5d

28+2=15d

30=15d

2=d

YZ = 9d - 2 = 9. 2 0 2 = 18 - 2 = 16

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?
