Answer:
Yes
Step-by-step explanation:
The amount of money Albert receives is described by the expression
The graph is shown below.
To determine if the relation is a function, we can use the vertical line test:
If a vertical line crosses the graph more than once in any location, the relation is not a function.
We see that at no place will a vertical line intersect the graph more than once.
The relation is a function.
To determine the answer it would be helpful if we write this equation into the slope intercept form which is expressed as:
y = mx+b
<span> y−2x=816
y = 2x + 816
4x=2y
y = 2x
We can see that the slope of the two equations are the same. Therefore, they are parallel which means they do not intersect. The correct answer is the third option, there is no solution.</span>
Answer:
D or B
Step-by-step explanation:
Brooke needs to get a 98 on the final to get an average of 80.
So you know that the total of the five given score is 382 by adding all the scores.
Now you multiply the average, 80 by 6 for the total of six tests including the final which is 480
Then you subtract 480-382 to find your answer.
