2. Determine if either of the following equations are functions? Draw the graphs and explain how

nekit [7.7K]

Answer:

Both equation represent functions

Step-by-step explanation:

The function is the relation that for each input, there is only one output.

A. Consider the equation

$y=-\dfrac{3}{5}x+2$

This equation represents the function, because for each input value x, there is exactly one output value y.

To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.

When you intersect the graph of the function $y=-\dfrac{3}{5}x+2$ with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.

B. Consider the equation

$y=x-x^2$

This equation represents the function, because for each input value x, there is exactly one output value y.

When you intersect the graph of the function $y=x-x^2$ with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.

Jenna and her 2 sisters want to take a camping trip. they have $125 saved. each of them will save $24 a week until they have $42

Alexxandr [17]

Answer:

After 4 weeks they have $413

After 5 weeks they have $485 (more than enough money)

Step-by-step explanation:

we know that here are 3 people saving up this money and we know that they have already saved 125 dollars.

if each saves $24 per week... 24*3=72 (total profit per week)

for 4 weeks... 72*4=288

288+125(already saved up)= 413

If they go one more week and save up another 72 dollars in 1 week this will bring them past their goal

The drama club is planning a field

Inessa [10]

Answer:

$\frac{2}{3}s+8=48$ .

Step-by-step explanation:

If we indicate the amount of students in the drama club as"s", we know that $\frac{2}{3}s$ is attending to the trip.
We also know that there are will be 8 teachers in the trip as well.
If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the $\frac{2}{3}s$ of the students: $\frac{2}{3}s+8=48$ .

Then, the equation that describes the situation is $\frac{2}{3}s+8=48$ . If we subtract 8 from both sides of the equation, and then we have $\frac{2}{3}s=40$ , which means that s=60.
