What is the probability of getting heads while flipping a coin and getting a number greater than or equal to 5 when rolling a si
iogann1982 [59]
So 1/2 for the Coin and 2/6 or 1/3 for the Coin 

So you need to add them

1/2 + 1/3 

you'll multiple the Numerators and denominators

1x1= 1

2x3= 6

Answer: So you have  1/6 chance of flipping a Coin on heads and also rolling 5 or greater on a dice :)

In rectangle FGHI, diagonals FH and GI intersect at E. G F E H I • IE = 3x + 4 • EG = 5x - 6 What is the length of FH ?​
timurjin [86]

Answer:

FH = 38

Step-by-step explanation:

Here, given the point of intersection of the two diagonals at E, we want to calculate the length of FH

The point of intersection of the diagonals is the midpoint of each as the diagonals bisect each other

thus,

3x + 4 = 5x - 6

5x-3x = 6+ 4

2x = 10

x= 10/2

x = 5

but Eg is 5x-6

and FH = 2EG

FH = 2(5x-6)

FH = 10x - 12

Substitute x = 5

FH = 10(5) -12

FH = 50-12

FH = 38

X intercept f(x)=(x+4)^2
natali 33 [55]

Answer:

<h2>-4</h2>

Step-by-step explanation:

Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x)  = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;

0 = (x+4)^{2} \\

Taking the square root of both sides

\sqrt{(x+4})^{2}  = \sqrt{0}\\ x+4 = 0\\

Subtracting 4 from both sides of the equation

x+4-4 = 0-4\\x = -4

Therefore the x intercept of the equation is -4
