Step-by-step explanation:

3x - 2y = 12

Substituting y = 9, we find:

$3x - 2 \times 9 = 12 \\ \therefore \: 3x - 18 = 12 \\ \therefore \: 3x = 12 + 18 \\ \therefore \: 3x = 30 \\ \therefore \: x = \frac{30}{3} \\ \therefore \: x = 10 \\ \therefore \: A (...., 9) = A (10, \: 9)$

Similarly, solving for point B (4, __) =B (4, 0)

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

astraxan [27]

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

$60\:\times 2^{-2}$

$=60\times \frac{1}{2^2}$ ∵ $a^{-b}=\frac{1}{a^b}$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=\frac{1\times \:60}{2^2}$

$=\frac{60}{2^2}$

$=\frac{2^2\times \:3\times \:5}{2^2}$

$=3\times \:5$

$=15$ gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

Factor Completely: -3x - 9

uranmaximum [27]

Step-by-step explanation:

-3x-9

divide the equation by -1 so that the -1's are taken from -3x and -9. so the -1 goes on the outside of 3x+9

-1(3x+9)

then divide the equation by 3 since 3x and 9 is divisible by 3.

(-1)(3)(3/3x+9/3)

-3(x+3)

Now we can expand again to check the problem

-3 times x=-3x

-3 times 3=-9

and add

-3x-9

Hope that helps :)
