Answer:
independent system
Step-by-step explanation:
The first linear equation () can be written in slope y-intercept form by solving for the y variable. When it is in that form, one can easily understand its geometrical shape and distinguish if it the same, if it crosses or if it is parallel, to the second line ()
We proceed to re-write it in slope y-intercept form:
Therefore it has a slope of "-1" and a y-intercept of "-5", while the second line has slope "1" and y-intercept "-7".
Therfore, they are lines that intercept at a unique point, and therefore represent an independent system.
Answer:
A)3.375
Step-by-step explanation:
0.75 * 4.5 = 3.375
Answer:
Part A)
Part B)
Part C) The graph in the attached figure
Step-by-step explanation:
Part A) Model with an inequality.
Let
w -----> the limit of weight in an elevator
we know that
The inequality that represent this situation is
Part B)
Solve the inequality
solve for w
Subtract 35 sides
All real numbers greater than 1,015 pounds
Part C) Where would the solution for the inequality be graphed on the number line?
The solution is the interval -------> (1,015,∞)
In a number line is the shaded area at right of the number x=1.015 (open circle)
see the attached figure
Ones negative and ones positive
First find the amount of time:
12 pm - 8 am = 4 hours
now divide the total miles traveled by the amount of time travleed:
1700 miles / 4 hours = 425 miles per hour
