We can do this two ways. For now, we can just do it the easiest way.
Since they are giving us coordinates, let’s just plug them in and see if they work.
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
So, (2,4) is not an answer. Let’s test 3,3.
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
It’s neither.
Now, we can see the other way.
-3x+5y=2x+3y
Let’s move the y to one side and the x to the other. Let’s subtract 3y from both sides.
-3x+2y=2x
Now add 3x.
2y=5x
We could’ve plugged in the x and y values with this as well.
But the answer would be neither.
Answer:
11/29/2020
Step-by-step explanation:
Every seventh and fifth day, both numbers are prime, 5 x 7 = 35, so 35 days after October 24th is November 29th because October has 30 days.
Are you trying to graph it?
There are indefinite answers.
Answer:
this answer requires that you do a little solving to find all the dimensions we need for the volume.
We know that H (height) = 2m
Diameter = 5 x height, so
Diameter = 5 x 2m = 10m
If you have the formula for finding the volume of a cylinder, it is basically the area of the circular base x cylinder height. You may know already that the area of a circle is (pi) x radius2
So this will be 2 (the height) x (pi) x r2
As we just figured out, the DIAMETER is 10, so the radius is half the diameter = 5.
This brings our volume to 2 x (pi) x 52
= 2 x (pi) x 25
2x25 = 50, so we have 50 x (pi).
Pi = 3.14
50 x 3.14 = 157
And don't forget your units = 157 m3
