Hi!
1in:4m
3in:xm
3/1 = 3
4 x 3 = 12
1in:4m
3in:12m
The answer is 12
Hope this helps! :)
Answer:
8meters
Step-by-step explanation:
Perimeter of the square ribbon = 4L
L is the side length of the table
Given
L = 2 meters
Substitute
Perimeter of the square ribbon = 4(2)
Perimeter of the square ribbon = 8meters
Hence she will need 8meters of ribbon to decorate the square
Answer:
b. ![\frac{1}{y^3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%5E3%7D)
Step-by-step explanation:
Here we are given
and are asked to simplify it. We are going to apply the law of exponents which says that
![a^{-n}=\frac{1}{a^n}](https://tex.z-dn.net/?f=a%5E%7B-n%7D%3D%5Cfrac%7B1%7D%7Ba%5En%7D)
Hence applying this rule in our problem we get, where a=y and n=3
![y^{-3}=\frac{1}{y^3}](https://tex.z-dn.net/?f=y%5E%7B-3%7D%3D%5Cfrac%7B1%7D%7By%5E3%7D)
Hence our C) Option is correct
The answer you are looking for is C
Answer:
y-1=0
Step-by-step explanation:
I'm going to write into y=mx+b form first.
m is the slope and b is the y-intercept.
First step is to find the slope.
To find the slope given two points you can use m=(y2-y1)/(x2-x1).
Instead, I like to line up the points and subtract vertically. Then put 2nd difference on top of 1st difference.
Let's do that:
(-2,1)
- (2,1)
--------
-4, 0
The slope is 0/-4=0. That means the line is horizontal and is of the form y=a number.
If you look at the points, you see the y-coordinate doesn't change. The y-coordinate is always 1. So the equation for the line is y=1.
If we subtract 1 on both sides we get y-1=0.
So general form is Ax+By+C=0 which is why I decide to move the one on the other side of the equation.
If I had noticed earlier that the y-coordinates were the same I would have stopped and say y=whatever y-coordinate I seen. However, I really didn't take notice of that until after I found the slope.
