Answer:
B
Step-by-step explanation:
Unit rate means one quantity in terms of another unit quantity. In the answer choices, we see that the denominator is always in terms of UNIT LITERS (1 L), so that means, we have to find gallons in terms of UNIT LITERS.
It means, we have to divide gallons by liters to get in terms of unitary liters.
Let's check the first line:
19.5/75 = 0.26 Gallons / 1 Liter
Now, checking 2nd:
39/150 = 0.26 Gallons / 1 Liter
So, yes, they are the same and other 2 lines would be the same as well. The unit rate is:
0.26 gal/1L
That's answer choice B
-the general equation is y=ax^2+bx+c
-the general equation is y=ab^x
-the graph contains a vertex
-the slope of the graph is constant and can be defined as rise over run
Answer:
The general equation is y=mx+b
the graph contains a vertex
the slop of the graph is constant and can be defined as rise over run
I would go for Y=mx+b
Answer:
Second option: Draw a graph that joins the points and and has a
Step-by-step explanation:
We know that the company charges $135 for 100 megabytes of data and $375 for 500 megabytes of data.
This gives us two points:
Then, we can find the slope of the line with this formula:
In this case we can identify that:
Substituting these values into the formula, we get that the slope is:
Therefore the best description for the steps to draw the graph is:
Draw a graph that joins the points and and has a slope of 0.6
Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 0.6 is correct.
To represent the relationship between total megabytes used (x) and total monthly charges (y).
We need to create a linear equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
Given that the telephone company charges $135 for 100 megabytes of data and $375 for 500 megabytes of data, we have two points: (100, 135) and (500, 375).
The slope (m) can be calculated using the formula:
m=y₂-y₁/x₂-x₁
m=375-135/500-100
=240/400
=0.6
So, the correct option is Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 0.6.
