Simplify the following rational expression and state for what values they are undefined.

d-2  and d cannot = 8

Step-by-step explanation:

d^2 -10d+16

d-8

Factor the numerator

( d-8)(d-2)

d-8

The undefined values occur when the denominator is equal to zero

d-8 = 0  

  d= 8

This means d cannot equal 8

Now cancel like terms in the equation ( d-8)

This yields d-2

d - 2 and d cannot equal 8

Step-by-step explanation: To simplify this rational expression, start by factoring both the numerator and the denominator.

So factoring the numerator in this problem, we have a

trinomial that factors as the product of two binomials.

So we are looking for factors of +16 that add to -10 which are -8 and -2.

So we have (d - 8)(d - 2) in the numerator.

The denominator doesn't factor however.

So we have and the d - 8's cancel leaving us with d - 2.

The values d cannot be happen when the denominator is set equal to 0.

So we have d - 8 = 0 which means d = 8.

This means d = 8 wouldn't work!

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?
