Answer:
a. The variable X represents the amount of hot dogs
b. the variable Y represents the amount of sodas
c. Their total expense would be $13.50
If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.
then you would add 10.50 and 3.00 to get $13.50
To find the coordinates of points A and B, go to Desmos and graph the given equation.
The word gradient means slope.
The slope is the coefficient of x in the equation. See it?
The gradient is 2.
The answer is DE/DF, which I'm assuming is option D. This is because sin is opposite/adjacent.
Thomas and his grandparents are on a trip of 140-mile. From Points D and E, there is no movement of the bus, which means they halt at the point.
<h3>What is a graph?</h3>
An orderly schematic illustration or diagram of facts or quantities is known as a graph in mathematics.
Usually, the graph's examples indicate how two or more items are related to one another.
As per the graph provided in the question,
As we can see in the graph there are covering 140 miles in a bus and the graph shows distance (in miles) and time (in hours).
From the graph we can see that between point D and E only time is increasing but the distance is constant which means they stopped at some place to halt.
