Answer:

r = 4

Step-by-step explanation:

19 = 7 - -3r

19 = 7 + 3r

Then you do Inverse Operations So you have to Subtract

19 - 7 = 12

12 = 3r

Then you do Inverse Operation So you have to Divide

12/3 = 4

So

19 = 7 - -3(4)

So Let's Make Sure That It Is Correct

19 = 7 - -3(4)

19 = 7 - -12

19 = 7 + 12

So 4 Is The Correct Answer

Multiply the binomials: (w-9) • (w-4)
Novay_Z [31]

Answer:

w² - 13w + 36

Step-by-step explanation:

Given

(w - 9)(w - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

w(w - 4) - 9(w - 4) ← distribute both parenthesis

= w² - 4w - 9w + 36 ← collect like terms

= w² - 13w + 36

Boyle's law states that for a fixed amount of gas, the volume of the gas at a constant temperature is inversely proportional to
BaLLatris [955]

Answer:

The answer is 41cmHg of pressure.

Step-by-step explanation:

If the volume of the gas is inversely proportional to the pressure that the gas exerts within the defined space that it is in, then for a gas that has a 50cmHg pressure at 9.84 liters of volume, the pressure it will have at 12 liters of volume can be found as Pfinal = (9,84 x 50) / 12 = 41cmHg of pressure for the same gas.

I hope this answer helps

Which is the best description of the graph of the function f(x)=60(1/3)^x
Ipatiy [6.2K]

Answer:

f(x)=60[1/3]^x

initial value⇒ x=0, f(x) = 60*[1/3]^0 = 60*1 = 60

x=1 ⇒f(1) = 60*[1/3]

x=2 ⇒f(2) = 60*[1/3]^2 = f(1) * [1/3]

x = n ⇒ f(n) = 60*[1/3]^n=60*[1/3]^(n-1)*[1/3] = f(n-1)*[1/3]

Then, the right choice is: the graph has an initial value of 60, and each successive term is determined by multiplying by 1/3

Step-by-step explanation:
