Yes, the price is proportional you can figure this out easily by taking each price and dividing by the amount for example $2.10 / 6 = 0.35 ,  $2.80 / 8 = 0.35  , $5.60 / 16 = 0.35

To solve the equation 2x−3=3x−7 , Esin graphs the functions f(x)=2x−3 and g(x)=3x−7 on the same set of coordinate axes.
Alecsey [184]
We have that

<span>f(x)=2x−3
g(x)=3x−7

2x-3=3x-7-------------> 3x-2x=-3+7-------> x=4 
find the value of f(x) or g(x) for x=4
</span>f(x)=2x−3 ------->  f(4)=2*4-3------> f(4)=5
<span>the solution is the point (4,5)

using a graph tool
see the attached figure

</span><span>statement

case a) </span><span>The solution of the equation cannot be found graphically. Esin should solve the equation algebraically.
this is not correct

case b) </span><span>The solution of the equation is the y-intercept of the linear equations.
</span>this is not correct

case c)<span>The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.
</span>this is correct

case d) <span>The solution of the equation is the y-coordinate of the ordered pair where the graphs of the two functions intersect
this is not correct

the answer is 
</span>case c) The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.

According to Trail Count, the annual survey of San Jose's off-street bicycle and pedestrian trail users, approximately 24% use t
ratelena [41]

Answer:

a) 0.5

Step-by-step explanation:

a)

Let T be the event that person uses trails daily and E be the event that person uses trails for exercise.

We have to find the probability that person uses the trails for exercise given that the person uses trails daily which can be denoted as P(E/T).

P(E/T)= P(E∩T)/P(T)

We are given that P(T)=0.24 and P(E∩T)=0.12. So,

P(E/T)= 0.12/0.24

P(E/T)= 0.5

Thus, the probability that person uses the trails for exercise given that the person uses trails daily is 50%

Solve for x:
Fantom [35]

2x + 6 + 3x + 12 = 33

5x + 18 = 33

5x = 33-18

5x = 15

therefore x=3
