The following ordered pairs form polygon wxyz: w(‒1, 3), x(2, 3), y(3, ‒1), and z(‒1, ‒1) which statement is not true? a. wx is perpendicular to wz. b. ∠wxy is a right angle. c. wx is parallel to zy. d. ∠wzy is congruent to ∠zwx.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
