Answer:
gravity is working
Step-by-step explanation:
gravity works on objects with energy
Answer:
B = 49/5 - 7a/5
A = = -5b/7 + 7
Step-by-step explanation:
Given that,
7a+ 5b= 49
Solution:
<em>Solving for a:</em>
Add -5b to both sides:
Divide both sides by 7:
Hence,a = -5b/7 + 7.
<em>Solving for b:</em>
Add -7a to both sides:
Divide both sides by 5:
Hence,b = 49/5 - 7a/5.
So,
Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6
![y = \frac{4}{-6} x - 4](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B4%7D%7B-6%7D%20x%20-%204)
Just use the slope to find the points you need.
The y-intercept is
(0,-4).The slope is
![\frac{4}{-6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B-6%7D%20)
. Finding the next point:
(-6,0)You could have also used the <em>slope intercept method.</em>
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
The answer is b because in order for it to represent a function, each input just has one unique output and never repeat
