PLEASE HELP WITH QUESTION, MARKING BRAINLIEST + POINTS!!!

1. This is a very easy question as you can just plug in 2 x-values and get the y-value, run a line through it, and you are done. 

For example,
x = 2t
x = 2(2) = 4
x = 2(3) = 6

Now, you know there are points at (2, 4) and (3, 6).

2. This one is a little tricky, but all it's saying is that it has a specified domain. The parametric equation only works for values -2 ≤ t ≤ 3. So, you can do the exact same thing, except your line will only exist for points through the x-values -2 and 3. Let's plug in numbers:

y = t + 5
y = -2 + 5 = 3
y = 1 + 5 = 6

Now you know that this line runs through (-2, 3) and (1, 6). Remember, your line starts at -2 and ends at 3. It can't go any further than that.

Can someone please help me with these!!!!!
Alona [7]
Yes, No, Yes, Yes, No. You fill in (x,y) numbers into the equations and if it cancels out into 4, it would be 4=4. If it doesn’t become 4=4, it’s no.

Naomi is a songwriter who collects royalties on her songs whenever they are played in
barxatty [35]

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and  the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

<em />x \to<em>  commercials</em>

<em />y \to<em> movies</em>

<em />

She earned a total of $300.

This is represented as:

20x + 100y =300

Her songs were played on 3 more commercials than movies.

This is represented as:

x = 3 + y

See attachment for the graphs of

20x + 100y =300

x = 3 + y

From the graph, the lines of both equations intersect at:

x = 5

y = 2

This means that:

  • <em>The number of movies is 2</em>
  • <em>The number of commercials is 5</em>

<em />
