What is the equation of a vertical line that has an x-intercept of -2?

1 answer:

IrinaVladis [17]3 years ago

4 0

As the line is vertical, it has same points for x - coordinates. And it never changes for whole line.
We know, slope (m) = y2 - y1 / x2 - x1
As x2-x1 = 0 [ x2=x1 ]

m = y2-y1 / 0
m = undefined

So, y = mx + c
y = c

In short, Your Answer would be y = c

Hope this helps!

G(t)=(t+1) ^2-20.25 what are the zeros of the function

Vinil7 [7]

Step-by-step explanation:

g(t) = (t + 1)² − 20.25

0 = (t + 1)² − 20.25

20.25 = (t + 1)²

±4.5 = t + 1

t = -1 ± 4.5

t = -5.5 or 3.5

The zeros are (-5.5, 0) and (3.5, 0).

The ratio of my action to comedy movies is 4:5. If I have 35 comedy movies, how many are action? *

iogann1982 [59]

Answer:

28 action movies

Step-by-step explanation:

Set up a proportion: $\frac{4}{5} = \frac{x}{35}$
Cross multiply, then divide: 35 × 4 = 140, 140 ÷ 5 = 28
So, if you have 35 comedy movies, you would have 28 action movies.

I hope this helps!
