Answer: a=8
Step-by-step explanation:
The rate of change of function is given by :-
For , linear function, the rate of change of function remains constant.
From, x=3 and x=4, we have
Since , the rate of change k= +5 (given)
Then, 
Hence, the value of a is 8.
If goal post is rectangle shaped then u can see distance of bc base is 3 times of its sides(distance from top to ground)(imagine aectangle)
So let x be the distance so bc=3x
Perimeter is given now u just put values in a formua of perimeter
60
30 *2
15 * 2 * 2
5 * 3 * 2 * 2
Remember for any two polygons
Area of polygons is directly proportional to square of sides
So
- BC²/XY²=135/15
- 15²/XY²=9
- (15/3)²=XY²
- XY=5in
#35
- HJ²/XY²=168/378
- 8²/XY²=0.44
- XY²=64/0.44
- XY²=145.45
- XY\approx 12+
Answer:
the answer is y=1x+(-1) or just 1x-1
