Identify the constant of proportionality from the table x y
2 12
4 24
5 30
9 54
A. 1/6
B. 2
C. 12
D. 6

Explanation:

Direct proportion equations are in the form y = kx, for some constant k.

The k value is the constant of proportionality. Solving for k leads to k = y/x.

For each row in the table, divide the y value over the paired x value.

Each row leads to the same k value, so the constant of proportionality is 6.

The equation y = kx updates to y = 6x.

This line has slope 6 and y intercept 0.

All direct proportion equations go through the origin.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
