Answer:
Option B gives the directly proportional relation.
Step-by-step explanation:
If a function can be written as in the form y = kx ........... (1), where x is the independent variable, y is the dependent variable and k is the proportionality constant.
Now, from the given four tables in options, the table in option B only satisfies this relation between x and y.
The ordered pairs in the option B are (1,0.5), (2,1), (3,1.5) and (4,2).
Now, take any two pairs of coordinates and find the equation of the function that satisfies all four points.
Taking (1,0.5) and (2,1) points, the equation of the straight line will be
⇒ 2(y - 1) = x - 2
⇒ 2y = x
⇒ 
............. (2)
Therefore, this equation (2) is similar to equation (1) and hence this table is directly proportional relationship. (Answer)
System of equation consists of two or more equations with unknow variables. A possible step used in eliminating the y-term is (y + z 6) *5
<h3>System of equations</h3>
System of equation consists of two or more equatons with unknow variables.
Given the system of equations
y + z = 6
5y + 9z =1
In order to eliminate the variable "y", we <em>will multiply equation 1 by 5 and subtract from equation 2;</em>
5y + 5z = 30
5y + 9z = 1
Subtract
5z - 9z = 30 - 1
-4z =29
This leaves only the variable "z" eliminating variable. "y"

Step-by-step explanation:
Answer:
547
Step-by-step explanation:
Answer:
The total distance they will travel on their trip is 308 miles.
Step-by-step explanation:
This question can be solved using a rule of three.
114 miles is 37% = 0.37. How many mines are 100% = 1?
114 miles - 0.37
x miles - 1
Rounding to the nearest mile
The total distance they will travel on their trip is 308 miles.
