Answer:

$y = \frac{18 - 3x}{ - 6}$

Step-by-step explanation:

Given,

$3x - 6y = 18$

$- 6y = 18 - 3x$

$y = \frac{18 - 3x}{ - 6}$

This how we can solve for y.

Prove this trigonometric identity sin 3x/sin x - cos 3x/cos x =2

Sveta_85 [38]

Step-by-step explanation:

LHS= sin 3x/sin x - cos 3x/cosx

Taking LCM,

=sin3xcosx- cos3xsinx

sinxcosx

=sin(3x-x)

sinxcosx

= 2sin2x

2sinxcosx

= 2sin2x

sin2x

= RHS.

Point D is on line segment CE.Given CD = X, DE = 7, and CE = 2x, determine the numerical length of CD

Usimov [2.4K]

Answer:

CD = 7

Step-by-step explanation:

Since D is on the line segment CE then

CE = CD + DE , substitute values

2x = x + 7 ( subtract x from both sides )

x = 7

Thus

CD = x = 7

If it took Carlos 1/2 hour to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 mile

Dvinal [7]

Answer:

Step-by-step explanation:

Given

time taken by Carlos to cycle is $t=0.5\ hr$

For case (1)

Average speed $v_{avg}>16\ ft/s$

For $0.5 hr \approx 30\times 60=1800\ s$

Distance traveled $d=1800\times 16=28,800\ ft\approx 5.45\ miles$

Therefore Carlos might not be able to cover 6 miles with average speed of 16 ft/s

(2) $v_{avg}=18\ ft/s$

for 0.5 hr

distance traveled

$d=1800\times 18=32,400\ ft\approx 6.136$

Therefore Carlos might be able to cover more than 6 miles with $18\ ft/s$
