We have that F is proportional to m1. Hence, we have that F=m1*c when we change the first mass. We also have that F=m2*c when we only change the 2nd mass. Since F scales inversely with the square of the distance, we have that
![F= \frac{c}{d^2}](https://tex.z-dn.net/?f=F%3D%20%5Cfrac%7Bc%7D%7Bd%5E2%7D%20)
. Combining all of the facts above, we get that F=c*
![\frac{m_1 m_2}{d^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bm_1%20m_2%7D%7Bd%5E2%7D%20)
where c is a constant.
Answer:
4/9
Step-by-step explanation:
Answer:
(2, 4)
Step-by-step explanation:
Given the system of equations
y=3×-2.... 1
y-2=× ... 2
Substitute 2 into 1
y = 3(y-2) - 2
y = 3y - 6 - 2
y - 3y =-6-2
-2y = -8
y = -8/-2
y = 4
Recall that
x = y - 2
x = 4-2
x = 2
Hence the solution (x, y) is (2,4)
Use slope formula as seen in the picture.
Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.
