Change the equation to slope intercept form and identity the slope and y-intercept -8x+2y=6

gulaghasi [49]

The answer is:

$y=4x+3$

The slope is: 4

The y-intercept is: 3

The explanation is shown below:

1. The slope intercept form of the linear equation is:

$y=mx+b$

Where $m$ is the slope and $b$ is the y-intercept.

2. Therefore, you must solve for <em>y</em>, as following:

$-8x+2y=6\\y=\frac{8x+6}{2}\\y=4x+3$

$m=4\\b=3$

If a car goes from 60 miles per hour to 10 miles per hour in 5 seconds, find its acceleration. Enter your answer as a whole numb

denis-greek [22]

Answer:

$a=-4.47\ m/s^2$

Step-by-step explanation:

Given that,

Initial speed of a car, u = 60 mph = 26.82 m/s

Final speed of a car, v = 10 mph = 4.47 m/s

Time, t = 5 s

We need to find the acceleration of the car. The rate of change of velocity is called the acceleration of an object. It can be given by :

$a=\dfrac{v-u}{t}\\\\a=\dfrac{4.47 -26.82 }{5}\\\\a=-4.47\ m/s^2$

So, the acceleration of the car is $4.47\ m/s^2$ and it is deaccelerating.
