They are supplementary because angle 12 is congruent with angle 10 which is supplementary with angle 7 ( that means the measure of angle7+ the measure of angle 12 is 180 grades)
12 and 10 are congruent due to the fact that A and B are two parallel lines and D is a sequent (i don't know how to spell this word). i guess you get it

The answer would be 200 because you would solve the equation 5.50+700=9n. Once you do, you end up with 200. And if you plug it in it equals the same.

Answer:

4.8 liters

Step-by-step explanation:

o=orange juice c=cranberry juice

Punch = 4/5o + 1/6c it means that any quantity of punch will have the same proportion of the two ingredients

now, you know that 1 liter can be written as 6/6 liters, so to get those 6/6 you multiply 1/6 by 6

for the proportion to remain valid, you must multiply by 6 also the other ingredient so (4/5)*6 = 24/5 of a liter of orange juice per liter of cranberry juice and 24/5 = 4.8 liters

D it

Step-by-step explanation:

We have two equations, A quadratic and a linear equation.

The domain of a linear equation and quadratic equation is all real numbers but since it dealing with time we must make sure the roots or x-intercepts is positive.

Looking at the quadratic equation, we can use the discramnt formula to see if all roots are positve.

$b {}^{2} - 4ac$
