Hi there!
One way to find the solution is to list out all of the possible combinations- which, in most cases, will take a long time.
<u>Another more effective way</u> to find the possible combinations is to multiply the amount of each component together and find the product of all of the amounts of items combined.
In this case, you would multiply:
6 * 3 * 3 * 3 * 3
= 486.
So, there'd be 486 combinations.
Hope this helps!
Step-by-step explanation:
since you know already that it is a linear equation with a constant change rate (slope), you don't know the equation itself yet ?
you found the change rate (slope).
it is x goes up by 2, and y goes down by 6.
the slope is the ratio y/x representing the y and x changes, and it is always the factor of x.
"down" or "left" means "-","up" or "right" means "+".
the slope here is therefore
-6/2 = -3/1 = -3
so, we know the line function looks like
y = -3x + b
to get b we use one of the x y pairs like (1. 4)
4 = -3×1 + b
7 = b
and the full line function is
y = -3x + 7
It helps when you count decimal places to line up the numbers
Answer:
Step-by-step explanation:
From the table,
The common difference is
This means that , we can get the subsequent term by adding 5 to the previous term.
The recursive formula is
The correct choice is A
Answer:
=3y^2
Step-by-step explanation:
let,
length: x
width: y
According to condition,
x = 3y -----------(1)
Second condition
Perimeter = 2 (l + b)
80 = 2 (x + y)
x + y = 40 -------------(2)
To find area,
Area = L x B
=3y x y
= 3y^2
