Answer:

The last equation matches the graph

Step-by-step explanation:

The reason why this graphing correspond to y=-2^x is because we know the parent function of f(x)=2^x is going to be the reflection over the x-axis with respect to this graphing giving , in another word if we were to multiply -1 to 2^x then the function is going to go from monotonically increasing at interval x=(-infinite, infinite), to monotonically decreasing at x=(-infinite, infinite), which is going to look exactly the same as the giving graph

A deck of cards contains 10 black cards and 10 red cards. The first card drawn is not replaced before drawing the second card. W

Virty [35]

<h3>Answer: 9/38</h3>

Reason:

There are 10 red cards out of 10+10 = 20 total.

10/20 = 1/2 is the probability of selecting a red card.

If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19

Multiply the two fractions mentioned to get the final answer.

(1/2)*(9/19) = (1*9)/(2*19) = 9/38

"The length of a rectangle is 5/2 units greater than its width"

'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is $\sf\dfrac{5}{2}w$ .

Perimeter of a rectangle is:

$\sf P=l+w$

Plug in our value for the length:

$\sf P=\boxed{\sf \dfrac{5}{2}w+w}$
