Answer:
x + y = 680
5x + 7y = 3914
Step-by-step explanation:
Let the amount of students who purchased tickets equal x.
Let the amount of adults who purchased tickets equal y.
If you add the amount of adults and students, you get the total amount of people:
x + y = 680
Also, to find the amount students spent on tickets, you multiply the ticket price by the amount of students to get 5x. And to find the amount adults spent on tickets, you multiply the ticket price by the amount of adults to get 7y. By adding the two amount, you get the total amount of money:
5x + 7y = 3914
These are the two equations:
x + y = 680
5x + 7y = 3914
The first function is y = 4x + 5 so the slope is 4
To find the slope of the second function, do rise or run which is 6-10/1-3 = 2
since 4 is greater than 2, function 1 is greater so the answer is the second choice.
Answer:
Scale factor = 1.82 units.
Step-by-step explanation:
We have been given that side length OQ of our prei-mage is 9.4 units and side length OQ' after dilation is 17.1 units. Since our pre-image (original image) is smaller than our new image, so our scale factor (r) will be greater than 1.
Since we know that in a dilation, the sides of the pre-image and the corresponding sides of the image are proportional, so we will use proportion to find a scale factor our given side lengths as:


Upon multiplying both sides of our equation by OQ we will get,


Upon rounding our answer to nearest hundredths place we will get,

Since side length OQ' is 1.82 times side length OQ, therefore, our scale factor (r) will be 1.82 units.
Answer: 20-2x/-4
Step-by-step explanation:
To actually solve for y as a number, you need two equations.
For this case move the 2x to the other side, making the equation -4y=20-2x.
Then divide by -4 on each side making the equation y=20-2x/-4.
