b. the slopes of both functions are positive
Step-by-step explanation:
hope this helps :)
Answer:
C. The slope of function A is positive and the slope of function B is negative.
Step-by-step explanation:
For this problem, you need to determine the slope of each function.
For function A:
You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.
So the slope for function A is 1/4.
For function B:
You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)
Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].
Therefore, the slope of function A is positive and the slope of function B is negative.
y = 2x + 1
y = 4x - 1
Solve by graphing
Answers
Answer:
See attached graph
Step-by-step explanation:
Because both expressions are equal to y, they'll intersect each other at a certain point, which is the solution to the system of equations. In this case, as shown by the graph, the point of intersection is (1,3) which means x=1 and y=3.

Justin likes to get 7 hours of sleep. He woke up after sleeping for 5 1/3 hour. How many more hours does he need to get the amount of sleep he likes?
Answers
Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes
1/3 hours = 60/3 = 20 minutes
Hours Minutes
7 00 when we borrow 1 hour we borrow 60 minutes
5 20
1 40
He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours
