Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).

Step 1: d = StartRoot (negative 7 minus (negative 7)) squared + (negative 4 minus (negative 2)) squared EndRoot

Step 2: d = StartRoot (negative 7 + 7) squared + (negative 4 + 2) squared EndRoot

Step 3: d = StartRoot (0) squared + (negative 2) squared EndRoot

Step 4: d = StartRoot 0 + 4 EndRoot

Step 5: d = StartRoot 4 EndRoot

Therefore, d = 2.

Tyree’s solution is inaccurate. In step 3, he added incorrectly.

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Explanation:

I got it right,

Hope this Helps!

you should at least use a calculater

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
