How many solutions y=5x-4 y=5x-5

Mathematics
1 answer:
AlladinOne [14]3 years ago
8 0

Answer:

No solution

Step-by-step explanation:

Any equations with the same slope are parallel, or will never intersect.

In a slope-intercept equation, this would mean the 'm' values are the same.

y = mx + b

Two equations:

y = 5x - 4

y = 5x - 5

Since the two equations given have the same slope, they will never intercept and therefore have no solution.

Maria is climbing a mountain. Maria's elevation, E(t) , in feet after t minutes is given by E(t) = 1200 + 40t.
svetlana [45]

E(t) is the elevation Maria is at at t minutes.

The expression to calculate the elevation is 1200 + 40t.

E(t) = 1200 + 40t

E(15) means the elevation Maria is at at time 15 minutes.

E(15) = 1200 + 40(15)

E(15) = 1200 + 600

E(15) = 1800

E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.

While passing a slower car on the highway, i accelerate uniformly from 12 m/s to 24 m/s in a time of 10.0s. How far do you trave
Taya2010 [7]
You say that there is uniform acceleration so:

vf-vi=at  (final velocity minus initial velocity is equal to acceleration times time)

We know vf, vi, and t so we can solve for acceleration:

24-12=a10

12=10a

a=1.2

That is the acceleration, we will need to integrate with respect to time twice...

v=⌠a dt

v=at+vi  , we know a=1.2m/s^2 and vi=12m/s

v=1.2t+12, 

x=⌠1.2t+12 dt

x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem...

x(t)=0.6t^2+12t

Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:

x(10)=0.6(10^2)+12(10)

x(10)=60+120

x(10)=180 meters
