Step-by-step explanation:
Answer:
Lol this is my first time seeing someone saying I bet no one will answer this. Ok coming back to the topic answers are :-
Initial value = -18
Initial value is the output value or the y variable. Looking in the table the y variable is -18 since x is 0.
Rate of change = 0.5
You have to use the formula of rate of change to find the answer. You can choose any pairs from the table and will give you the same answer. I pick the first pair and the last pair to find my rate of change.
(0, -18) and (36, 0)
x1, y1 x2, y2
Rate of change = y2 - y 1 / x2 - x1
Rate of change = 0 - (-18) / 36 - 0
Rate of change = 18 / 36
Rate of change = 0.5
Hope this helps, thank you :) !!
We already know that PQ and ST are congruent because they both equal 4 and QR and TU are congruent because they both equal 6. Also I'm not sure if it is marking the two angles congruent but it looks like that to me so if that is the case then both of the triangles are congruent by SAS, PQ=ST, WR=TU, angle PQR = angle STU.
Now that we need to set up a system of equations to find y. Since we already proved the triangles congruent SU must be = to PR because of CPCTC "corresponding parts of congruent triangles are congruent" So the equation would be:
3y-2=y+4 (move y variable to one side) subtract y from right, add 2 to right
2y=6 (divide)
y=3
Then plug 3 into where y is (and since we need PQR perimeter plug it into 3(3)-2) and PR should equal 7 so add up all the sides (4+6+7) and your perimeter is 17ft.
