Answer:
scale triangle its side are not equal
Answer: y = 5/6x - 2
Step-by-step explanation:
Y =mx + b
Step 1 find slope also known as m:
Y2 - y1 / x2 - x1
3-(-7)/6-(-6) = 10/12 can be reduced to 5/6
Step 2 find b:
3 = 5/6 (6) + b
3 = 30/6 + b
3 = 5 + b
-5 - 5
-2 = b
Step 3 write equation:
Y = 5/6x - 2
Area of the rectangle
.
Solution:
Given data:
Height of a rectangle = ![t^2+7t+6](https://tex.z-dn.net/?f=t%5E2%2B7t%2B6)
Width of a rectangle = ![2t+1](https://tex.z-dn.net/?f=2t%2B1)
Area of the rectangle = height × width
![=(t^2+7t+6)\times(2t+1)](https://tex.z-dn.net/?f=%3D%28t%5E2%2B7t%2B6%29%5Ctimes%282t%2B1%29)
Multiply each term of height with the each term of width.
![=(t^2+7t+6)2t+(t^2+7t+6)1](https://tex.z-dn.net/?f=%3D%28t%5E2%2B7t%2B6%292t%2B%28t%5E2%2B7t%2B6%291)
![=(2t^3+14t^2+12t)+(t^2+7t+6)](https://tex.z-dn.net/?f=%3D%282t%5E3%2B14t%5E2%2B12t%29%2B%28t%5E2%2B7t%2B6%29)
![=2t^3+14t^2+12t+t^2+7t+6](https://tex.z-dn.net/?f=%3D2t%5E3%2B14t%5E2%2B12t%2Bt%5E2%2B7t%2B6)
Adding like terms of the polynomial.
![=2t^3+15t^2+19t+6](https://tex.z-dn.net/?f=%3D2t%5E3%2B15t%5E2%2B19t%2B6)
Therefore, Area of the rectangle
.
Answer:
The first one
Step-by-step explanation:
It says that the value of <em>t</em> is more than or equal to -4 and less than or equal to 2.
An equation of the line is :
![y=mx+p](https://tex.z-dn.net/?f=y%3Dmx%2Bp)
where m is the slope ; so we have :
![y=\frac12x+p](https://tex.z-dn.net/?f=y%3D%5Cfrac12x%2Bp)
Can you find the value of
![p](https://tex.z-dn.net/?f=p)
?
