Step-by-step explanation:

Hey there!

Given equations are;

2x+3y = 15(i)

4x+6y = -48…………(ii)

From eqaution (i)

2x+3y = 15

Slope (m1) = (-coefficient of x)/(coefficient of y)

Slope (m2) = (-2)/(3)

Therefore, slope (m1) = -2/3.

From eqaution (ii).

4x+6y= -48

Slope (m1) = (-coefficient of x)/(coefficient of y)

Slope (m2) = (-4)/6

Therefore, slope (m2) = -2/3.

Now;

Condition of parallel lines: m1=m2

-2/3 = -2/3

So, they are parallel.

Hope it helps

Parallel

Step-by-step explanation:

2x + 3y = 15

3y = -2x + 15

y = -2/3x + 5 (slope = -2/3)

4x + 6y = -48

6y = -4x - 48

y = -2/3x - 8 (slope = -2/3)

Since the slopes are the same, they are parallel.

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'.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
