6 0

Answer:

y = -1

Step-by-step explanation:

1) Plug in the slope (0) into y = mx + b

y = 0(x) + b

2) Plug in (-3,-1), x = -3, y = -1

-1 = (0)-3 + b

3) Isolate b

b = -1

4) Construct the line equation (y = mx + b)

y = -1

If carlos did some work and got 3x + 2x - 6 = 24 what mistake did he make

Makovka662 [10]

Carlos made the mistake that he did not combine like terms (3 x and 2 x) properly and did not use addition property of equality.

Step-by-step explanation:

Carlos did the work as 3 x + 2 x - 6 = 24

We need to find his mistake that he made in above given.

Here, he did not add the like terms (3 x and 2 x)

3 x + 2 x = 5 x

Therefore, his work should be

5 x - 6 = 24

Also, he did not use addition property of equality. It means the equation remains same even though the same number gets added on both sides. It would be

5 x - 6 = 24

+ 6 = + 6

-----------------------

5 x = 30

Dividing 30 by 5, we get answer as '6'. Hence,

$x=\frac{30}{5}$ = 6

So, stated the above two are the mistakes found in carlos work.

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle

zimovet [89]

Answer: $\left | 2t-5\right |,\ 2,\ 2t-5$

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

$s(t)=t^2-5t+1$

Speed of the particle is given by

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left | 2t-5\right |$

Acceleration of the particle is

$\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2$

velocity can be negative, but speed cannot

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5$
