x represents the new value.
This multiplies 660, the starting value, by 110% for each year (t).
Answer:
y = - 8
Step-by-step explanation:
y = 3 is the equation of a horizontal line parallel to the x- axis.
The equation of a parallel line must therefore be a horizontal line with equation
y = c
where c is the value of the y- coordinates the line passes through.
Here the line passes through (- 2, - 8) with y- coordinate - 8, thus
y = - 8 ← equation of parallel line
Step-by-step explanation:
When something is inversely proportional it can be solved by using the equation:
y = k/x
where k is the constant.
So using this we can plug in x and y to find the value of k.
27= k/3
Next we isolate k and find that k = 81. Now we use this to find the value of x when y = 9. Plug in y and you get x = 81/9 or x = 9
