Linear mathematical models describe real world applications with the use lines. For instance, a car going 50 mph, has traveled a distance represented by y=50x, where x is time in hours and y is miles. The equation and graph can be used to make predictions.
Answer:
Step-by-step explanation:
The like terms are the ones containing the variable 'c'. They are combined by adding their coefficients.
Working just with the coefficients of c, we have ...
Then the simplified expression is ...
(2 3/4)c +(3 1/8)c +7
= (5 7/8)c +7
Answer:
$21.60
Step-by-step explanation:
18/5 is 3.6, so 18+3.6 or 21.6
Hope this helps :D
Answer:
y = x - 12
Step-by-step explanation:
Since the lines are parallel, the slopes are the same.
The desired equation has the form y = x + 1. Replacing the constant (1) by C, we get y = x + C. Finally, we substitute 12 for x and 0 for y in y = x + C to determine the value of C:
0 = 12 + C, or C = -12
Then the equation of the line is y = x - 12.
