Hello!
We separate this into three sections
we are looking for a graph that has a line where x is greater than -3 and less than -2 while the circles not shaded since it does have the or equal to sign
The graphs that have this is the first and the third
Next we can look for the graph that has x greater than or equal to -2 and less than 3 with the one at -2 shaded but the one at 3 not
The graph that follows this is the third graph
The answer is the third one
Hope this helps!
The acceleration is defined as the ratio between the change in velocity and the time elapsed to perform such a change.
These "changes" are indicated with the capital greek letter delta,
, and when you write
you mean the difference between the finial and the inital values of the variable x:
![\Delta x = x_{\text{fin}} - x_{\text{init}}](https://tex.z-dn.net/?f=%20%5CDelta%20x%20%3D%20x_%7B%5Ctext%7Bfin%7D%7D%20-%20x_%7B%5Ctext%7Binit%7D%7D)
So, the acceleration is defined as
![a = \dfrac{\Delta v}{\Delta t} = \dfrac{v_{\text{fin}} - v_{\text{init}}}{t_{\text{fin}} - t_{\text{init}}}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cdfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D%20%3D%20%5Cdfrac%7Bv_%7B%5Ctext%7Bfin%7D%7D%20-%20v_%7B%5Ctext%7Binit%7D%7D%7D%7Bt_%7B%5Ctext%7Bfin%7D%7D%20-%20t_%7B%5Ctext%7Binit%7D%7D%7D)
In this case, the initial velocity is 35, the final velocity is 65. Assuming we start the clock at the beginning of the observation, the inital time is 0 and the final time is 5. So, we have
m/s^2
Answer:
19
Step-by-step explanation:
Angle ZYW is congruent to angle YWX, so the 3 angles must add to 180.
(3x - 5) + 90 + 2x = 180
5x + 85 = 180
5x = 95
x = 19
Answer: y=2x-3
Step-by-step explanation:
divide both sides by 7
7y/7=(14x-21)/7
y=2x-3
