A dolphin is swimming to the surface of the ocean while at the same time a bird is flying towards the surface of the ocean. The

function fx) models the position, in feet, of the dolphin x seconds after it starts swimming towards the surface. The function models the dolphin's position for the first 5 seconds The function g (x) models the position, in feet, of the bird x seconds after the bird begins flying towards the surface. The function models the bird's position for the first 5 seconds. A partial table of values ​​for the two linear functions is shown. x f (x) g (x) 0.0-11 10 0.59 9 1.07 8 1.55 7 2.0 -3 6 2.5 -1 5 After how many seconds will the dolphin and bird be at the same position?

Answer:

The dolphin and bird be at the same position will be at the same position after 3.5 seconds

Step-by-step explanation:

The general equation of a line is h(x) = m*x + b, where m is the slope and b is the y-axis interception. We can get m and b from data as follows. To get m, we need 2 points (x1,y1) and (x2, y2) and the next formula m = (y2 - y1)/(x2 - x1).  

For f(x), using (0.5, -9) and (0, -11)

m = (-9 - (-11))/(0.5 - 0) = 4

For g(x), using (0.5, 9) and (0, 10)  

m = (9 - 10)/(0.5 - 0) = -2

To get b, we need to see f(x) and g(x) values at x = 0. So, for f(x), b = -11 and for g(x), b = 10. Then,  

f(x) = 4*x - 11

g(x) = -2*x + 10

The dolphin and bird be at the same position when f(x) be equal to g(x). Mathematically :

f(x) = g(x)

4*x - 11 = -2*x + 10

4*x + 2*x = 10 + 11

6*x = 21

x = 21/6

x = 3.5 seconds

you are on a 750 mile trip by car . ur car used seven gallons of gas to travel the first 210 miles of the trip. how much more ga
stepan [7]

Answer:

A total of 18 gallons of more gas

Step-by-step explanation:

7 gallons = 210 miles

750-210= 540

210*2 =420 miles       7*2=14 gallons

210/2= 105                  7/2=3.5 gallons

525 miles                       17.5 miles

210/14= 15                      7/14=.5 gallons

540 miles                    18 gallons

2t-2=26
first you would add 2 to both sides
that equals 2t=28
then you would divide both sides by two
that would give you
t= 14
