Answer:

Option : ( 2 , 6 )

x = 2, y = 6

Step-by-step explanation:

y = 4x - 2      ---------------- ( 1 )

y = -2x + 10   -------------- ( 2 )

<em><u>Substitution Method</u></em>

Substitute ( 1 ) in ( 2 ) :

                           4x - 2 = -2x + 10\\\\4x + 2x = 10 + 2\\\\6x  = 12\\\\x = 2

Now substitute x in ( 2 ):

                           y = -2x + 10\\\\y = -2 ( 2 ) + 10\\\\y = - 4 + 10 \\\\y = 6

Wyatt’s eye-level height is 120 ft above sea level, and Shawn’s eye-level height is 270 ft above sea level. How much farther can
brilliants [131]
Using the formula given: d = <span>√(3h/2)

We simply substitute the given values of h into the equation and compare the results.

For Wyatt where h = 120:
d = </span>√(3(120)/2)<span>
d = 13.42 miles

</span><span>For Shawn where h = 270:
d = </span>√(3(270)/2)<span>
d = 20.12 miles
</span>
Since the question asks for how much farther can Shawn see, we subtract the results:

20.12 - 13.42 = 6.7

Therefore, Shawn can see 6.7 miles farther.

A stick has a length of $5$ units. The stick is then broken at two points, chosen at random. What is the probability that all th
Zinaida [17]

Answer:

4/25 = 0.16

Step-by-step explanation:

The shortest stick must be between 0 and 5/3.  The probability that it is longer than 1 is therefore:

(5/3 − 1) / (5/3 − 0)

(2/3) / (5/3)

2/5

So the probability that both of the shortest sticks are longer than 1 is (2/5)² = 4/25.
