Answer:
4 and 20
Step-by-step explanation:
100 times 5 is 500. If we go backwards 500 ÷ 5 = 100.
100 ÷ 5 = 20. 20 ÷ 5 = 4.
An exponential sequence is a sequence that grows more every time. It would get really big really quickly.
Move the constant to the right-hand side and change its sign
Subtract the numbers
Divide both sides of equation by 2
The solution of two equations/lines is their intersect point.
Therefore, there can only be one intersection point/solution, because these lines are neither parallel or identical.
In the graph you can see that they intersect at (x,y)=(2,3) which is your solution and option b or d as one of them seems to be mistyped :)
@question2
y=kx+b
both your equations share the same k=-2:
y=-2x+3
y=-2x-1
therefore these lines are parallel and don't have any intersection as they are always at different y values (the b)
Answer:
5000 aluminium cans
Step-by-step explanation:
So if the bring in ten aluminium bottles they make 1 dollar. If they bring in 50 they make 5 dollars.
If they 500 they make 50 dollars
If they bring in 5000 they make 500 dollars
Hope this helps!
Answer:
Step-by-step explanation:
Given:
The radius of a cylindrical gift box = 
The height of the gift box is three times the radius.
Question asked:
What is the surface area of the cylinder ?
Solution:
The height of the gift box is three times the radius means,
Now, surface area of the cylinder = 
\\=8\pi x+2\pi(16x+4)\\=8\pi x+32\pi x+8\pi\\=40\pi x+8\pi\\=8\pi(5x+1) \ Taking \ common](https://tex.z-dn.net/?f=%3D2%5Cpi%5B4x%2B1%5D%284x%2B1%2B12x%2B3%29%5C%5C%3D8%5Cpi%20x%2B2%5Cpi%2816x%2B4%29%5C%5C%3D8%5Cpi%20x%2B32%5Cpi%20x%2B8%5Cpi%5C%5C%3D40%5Cpi%20x%2B8%5Cpi%5C%5C%3D8%5Cpi%285x%2B1%29%20%5C%20Taking%20%5C%20common)
Therefore, surface area of the cylinder is .
