PLS ANSWER IT I just need the answer

aalyn [17]

The y-intercept is (0,2)

you can find the y-intercept by finding the value of y when x = 0

The slope is -5/2.

you can find the slope by using the equation below and any two points on the line, such as (0,2) and (2,-3)

$\frac{y2-y1}{x2-x1}=\frac{-3-2}{2-0} =\frac{-5}{2}$

Hope that helps!

Five cards (a hand) are dealt from a randomly shuffled deck of cards. For those of you that are not familiar with playing cards:

sp2606 [1]

Answer: 0.0004951

Step-by-step explanation:

Given

Five cards are from the deck

The total number of cards in the deck is 52

total spades card is $13$

We have to choose 5 cards out of 13, this can be done in

$\Rightarrow ^{13}C_5$

The probability of choosing 5 spade cards is

$\Rightarrow P=\dfrac{^{13}C_5}{^{52}C_5}\\\\\Rightarrow P=\dfrac{1287}{2598960}=0.0004951$

Three sides of a fence and an existing wall form a rectangular enclosure. The total length of a fence used for the three sides i

ss7ja [257]

<span>Let the wall's length be y. So the fence parallel is also y.

We form the equation;
2x + y = 240

Now the area A is x*y, which is given as 5500.

We have 2 equations with 2 variables. Solve them and get the answer.

xy = 5500
2x + y = 240

Y = 5500/x

2x + (5500/x) = 240
2x^2 - 240x + 5500 = 0
x^2 - 120x + 2750 = 0
Work out the value(s) of x from above. </span>
