Answer:
Option (a)
2x-10
Step-by-step explanation:
Area of shaded region= area of square - area of rectangle..
= s×s - l×b
= 2x -10...
angles in a triangle always equal to 180° so:
1. all the angles are equal to each other
180°÷3=60°
2.
•we know 1 angle, 68°
• straight lines are 180°-> 180°-126°= 54°
180°-68°-54°= 58°
Hello mate ☺️,
![2x + x + x + 2y \times 3y \times y](https://tex.z-dn.net/?f=2x%20%2B%20x%20%2B%20x%20%2B%202y%20%5Ctimes%203y%20%5Ctimes%20y)
Add 2x + x + x,
![4x + 2y \times 3y \times y](https://tex.z-dn.net/?f=4x%20%2B%202y%20%5Ctimes%203y%20%5Ctimes%20y)
Now multiply 2y x 3y x y,
![4x + 6y³](https://tex.z-dn.net/?f=4x%20%2B%206y%C2%B3)

Answer:
y = -40x+2600
Step-by-step explanation:
Writing the values as coordinate (m, s)
If after flying for 11 seconds, he is 2160 meters from her, the required coordinate is (11, 2160)
Then at 19 seconds he is 1840 meters, the required coordinate is (19, 1840)
Get the slope;
m = 2160-1840/11-19
m = 320/-8
m = -40
Substitute m = -40 and (11, 2160) into the equations;
y-y0 = m(x-x0)
y -2160 = -40(x-11)
y - 2160 = -40x+440
y = -40x+440 + 2160
y = -40x+2600
Hence the requires equation is y = -40x+2600
Answer:
f(x)=1/3x+2
g(x)=1/3x+5
Step-by-step explanation:
for f(x)
![m = \frac{rise}{run} = \frac{1}{3} \\ \\ y = mx + b \\ y = \frac{1}{3} x + 2](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Brise%7D%7Brun%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%5C%5C%20%20%5C%5C%20y%20%3D%20mx%20%20%2B%20b%20%5C%5C%20y%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%202)
So f(x) = 1/3x + 2
b is where the line hit y-axis
for g(x):
![m = \frac{1}{3} \\ y = \frac{1}{3} x + 5](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%5C%5C%20y%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%205)
So g(x) = 1/3x+5
