What is the value of x in the equation 2x + 3y = 36, when y = 6

The value of x would be 9.

As we already know, a variable is an unknown number, so a number beside a variable, is basically multiplying the 2 numbers. Now lets replace y with 6.

2x+3X6=36. Well 3X6 is 18, so 2x+18=36. Now we can reverse backwards.

36-18=18, so something times 2 is 18, 18 divided by 2 is 9. 2X9+3X6=36

The value of x is 9. 
2*9 + 3*6 = 18 + 18 = 36.

A baseball player get on base seven times and strikes out five times during the tournament. What is that experimental have abili
SOVA2 [1]
First you have to make the assumption that these are the only two outcomes. There is also the possibility of hitting the ball and getting out. 

However, if we assume that these are the only two cases, we know that the probability is 58.3%. This is because it has been on base 7 times out of 12.

Answer:

9/2π cm/s

Step-by-step explanation:

Volume of the spherical balloon V= 4/3πr³

Rate of change of volume dV/dt = dV/dr * dr/dt

dV/dr = 3(4/3πr²)

dV/dr = 4πr²

dV/dr = 4π(2)²

dV/dr = 16π

If V = 72cm²/s

72 = 16π*dr/dt

dr/dt = 72/16π

dr/dt = 9/2π cm/s

Hence the radius is changing at  9/2π cm/s

What is longer 180 seconds or 3 minutes
Neporo4naja [7]
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.

To one-one functions g and h are defined as follows.
Andreyy89

Answer:

  • 9
  • (x-8)/3
  • -1

Step-by-step explanation:

The inverse function for a set of ordered pairs can be found by swapping the x- and y-coordinates in each pair.

  g^{-1}(-1)=9\qquad\text{from the $g(x)$ ordered pair $(9, -1)$}

__

The inverse of a function expressed algebraically can be found by swapping the x- and y-variables and solving for y.

  h^{-1}(x)\qquad\text{is found from }x=h(y)\\\\x=3y+8\\x-8=3y\\\\y=\dfrac{x-8}{3}\\\\\boxed{h^{-1}(x)=\dfrac{x-8}{3}}

A function of its own inverse returns the original value:

  \boxed{\left(h\circ h^{-1}\right)(-1)=-1}
