Answer:

Ranges' (4.5, 4, 3.5, 3, 2.5, 2)

Step-by-step explanation:

x+2y=7

-2+2y=7

+2 both sides

2y=9

divide by 2

y=4.5

-1+2y=7

2y=8

y=4

0+2y=7

y=3.5

1+2y=7

2y=6

y=3

2+2y=7

2y=5

y=2.5

3+2y=7

2y=4

y=2

2. Find the cosine function that is represented in the graph.
Diano4ka-milaya [45]

Answer:

f(x) = cos(x - \frac{\pi }{4} ) -1

Step-by-step explanation:

In this graph, we have the coordinate point (\frac{\pi }{4} , 0). Without translations, cos(0) = 0, which means that the graph is shifted to the right by \frac{\pi }{4}. We also know that the graph is shifted down by 1 because we have the point

(\frac{5\pi }{4} , -2), but accounting for the right shift, this point should really by (\pi , -2). cos(\pi) = -1, but on the graph it is -2, meaning that it is shifted down by 1.

Therefore, accounting for the right shift by \frac{\pi }{4} and the shift down by 1, our equation is f(x) = cos(x - \frac{pi}{4} ) - 1.

At 3:30 p.m., Berto’s train was 34 miles past the egg farm, traveling at an average speed of 85 miles per hour. At the same time
timurjin [86]

E=egg farm

x=distantce between  the Berto´s trains and the meeting point.

t=time where the trains meet up

⇒110 miles/h                                          ⇒85miles/h

[---------------------------E----------------------]-------------------------------------X

[............12 miles.......][........34 miles.....][------------ x ----------------------]

distance between Berto´s train and Eduardo´s train=

=12 miles+34 miles=46 miles.

S=d/t      ⇒d=S*t

S=seed

d=distance

T=time

Eduardo´s train;

46 miles+x=t*110 miles/h  ⇒x=t*110 miles/h-46 miles  (1)

Berto´s train;

x=t*85 miles/h  (2)

With the equations (1) and (2) we suggest this system equations:

x=t* 110 miles/h-46 miles

x=t*85 miles/h

we solve this system equiations :

t*110 miles/h-46 miles=t*85 miles/h

110t miles/h-85t miles/h=46 miles

25 t miles/h=46 miles

t=46 miles/25 miles/h=1,84 hour  (≈1 hour, 50 minutes, 24 seconds)

x=t*85 miles/h=156,4 miles

Solution: 1,84 hour
