Determine whether statement (3) follows from statements (1) and (2) by the law of detachment or the law of syllogism. if it does, state which law was used. if it does not, write invalid. (1) she is a girl. (2) her name is chris. (3) chris is a girl's name.

The answer is invalid.

Step-by-step explanation:

This is invalid.

(1) She is a girl.

(2) Her name is Chris.

(3) Chris is a girl's name.

The Law of Syllogism states, “If p→q and q→r are true, then p→ r is also true.

The Law of Detachment states, “If p→q is true and p is true, then q is also true.”

Hence, this is invalid.

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?

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
