Answer: The equation that represents the other equation is
.
The solution of the system is <u>(3,6).</u>
Step-by-step explanation:
Linear equation:
, where m= slope
c = y-intercept.
In the first table, the y-intercept = 5 [ y-intercept = value of y at x=0.
Slope for first table = 
The equation that represents the first table:

So, the equation that represents the other equation is
.
Also, the solution of the system is the common point (x,y) that satisfy both equations in the system.
Here, x=3 and y=6 is the common value in both tables.
So, the solution of the system is <u>(3,6).</u>
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
Okay, so first divide 336 / 12 to find out how many miles are driven on each gallon. 336 / 12 = 28 So the car travels 28 miles per gallon (mpg).
Then, divide 1,344 / 28 1,344 / 28 = 48
And there's your answer! D) 48 gallons
The answer is C) 21, because 6/14 is simplified to 3/7. assuming it’s a pattern 3/7, 6/14, 12/21.
