Answer:
false
Step-by-step explanation:
Triangle = 5*6=30/2=15
Parallelogram = 6*5 = 30
Answer:
![\displaystyle m = \frac{1}{5}\cdot t](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7B1%7D%7B5%7D%5Ccdot%20t)
Step-by-step explanation:
<u>Proportional Model</u>
The number of miles m that Lexus can skateboard in t minutes can be modeled by:
m = kt
It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.
Substituting:
4 = k.20
Dividing by 20
![k=\frac{4}{20}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B4%7D%7B20%7D)
Simplifying:
![k=\frac{1}{5}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7B5%7D)
This produces the model
![\displaystyle m = \frac{1}{5}\cdot t](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7B1%7D%7B5%7D%5Ccdot%20t)
Answer:
7(x+1)^2 - 3
Step-by-step explanation:
To Write in The Vertex Form Simply means expressing the equation using completing of the square method
step 1: Make the coefficient of x^2 to 1
7 [x^2 + 2x + 4/7]
step 2: express the coefficient of x as half's of positive and negative
7 [x^2 + 2x + (1)^1 - (1)^1 + 4/7]
step 3: separate the negative part and the constant to solve then correct x^2 and 1^2 together
7 [ (x+1)^2 -3/7 ]
step 4 : distribute the 7
7(x + 1)^2 - 3
