To solve for b, you need to isolate/get the variable "b" by itself in the equation:

A = h(a + b) Divide h on both sides

$\frac{A}{h}=\frac{h(a +b)}{h}$

$\frac{A}{h} =a + b$ Subtract a on both sides to get "b" by itself

$\frac{A}{h}-a=a-a+b$

$\frac{A}{h} -a=b$

It is impossible to get 6 jacks when selecting cards from a shuffled deck. Express the indicated degree of likelihood as a proba

Vinil7 [7]

Answer:

Probability = 0

Step-by-step explanation:

If something happening is impossible, it's probability of occurring is also 0.

A deck of cards only contains 4 jacks.

Thus you can never get 6 jacks out of the deck without replacing the selected card each time.

Since we are not replacing the cards once we pick them, this event is impossible to occur.

Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27,

Vera_Pavlovna [14]

Answer:

$y=9x$

$y=\frac{18x}{2}$

$y=\frac{81x}{9}$

Step-by-step explanation:

The given equation is

$3y=27x$

If we isolate $y$ , we can find the constant

$y=\frac{27x}{3}\\ y=9x$

So, the constant is $k=9$ .

Another proportions that have the same constant as the given equation are

$y=9x$

$y=\frac{18x}{2}$

$y=\frac{81x}{9}$

Solve the equation <img src="https://tex.z-dn.net/?f=8x%5E2%3D-36" id="TexFormula1" title="8x^2=-36" alt="8x^2=-36" align="absmi

Answer: 4(2x²+9) or $i\frac{3\sqrt{2} }{2}$

Step-by-step explanation:

To solve the equation by factoring, we want to set the equation to zero. In order to have the equation equal to zero, we want to add both sides by 36.

8x²=-36 [add both sides by 36]

8x²+36=0

When it comes to factoring, we want to pull out numbers or variables that are common in each term.

8x²+36=0 [take out a 4 in each term]

4(2x²+9)=0

It may seem that 2x²+9 can be factored further, it actually can't. This tells us that the factored form of the equation is 4(2x²+9)=0.

To solve the equation, we want to find the value of x. We already know the graph does not cross the x-axis because the y-intercept or vertex is (0,9).

4(2x²+9)=0 [divide both sides by 4]

2x²+9=0 [subtract both sides by 9]

2x²=-9 [divide both sides by 2]

x²=-9/2 [square root both sides]

$x=\sqrt{-\frac{9}{2} }$ or $x=i\frac{3\sqrt{2} }{2}$
