5) The height of a rocket after it is launched
 For this case, what you should do is remember the kinematics expressions where we have:
 a
 v = a * t + vo
 y = a * t ^ 2 + vo * t + i
 Where,
 a: acceleration
 v: speed
 y: vertical position
 t: time
 vo: initial speed
 yo: initial position
 We observe that the expression for the given position is given by a quadratic expression.

Write the following equation in slope- intercept form 6x+2y=20
lorasvet [3.4K]

Answer:

y = -3x + 10

Step-by-step explanation:

6x+2y=20

First, you want to subtract 6x from both sides.

2y=-6x+20

Now, you want to divide by 2 on both sides because you want to get y by itself.

y = -3x + 10

Step-by-step explanation:

(–3÷(–3/(x–2)))+2

=((–3×(x–2))÷(–3))+2

=(1×(x–2)÷1)+2

=(x–2)+2

=x

What does it mean by domain and range and how would I use that to fill out the table?​
Sav [38]

The domain is the set of all allowed x values. In this case, we consider the whole numbers between 0 and 10. So we have x = 0, x = 1, x = 2, ... all the way up to x = 10.

To find the y values, you replace each x with the numbers mentioned and simplify.

For instance, if x = 2, then,

f(x) = 3.50x

f(2) = 3.50*2

f(2) = 7

This tells us that x = 2 packages cost y = 7 dollars.
