1/100,000,000 , note that 100,000,000 = 10⁸ , then:
1/100,000,000 = 1/10⁸
Remember that 1/aⁿ = a⁻ⁿ
Hence 1/100,000,000 = 1/10⁸ = 10⁻⁸
Answer:
Step-by-step explanation:
<h3>Given</h3>
- If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm
- s = ?
<h3>Solution</h3>
<u>Add up the 3 equations and solve for s:</u>
- s - a + s - b + s - c = 5 + 10 + 1
- 3s = 16 + a + b + c
- s = 1/3(a + b + c + 16)
First thing you should do is reduce coefficients.
1st equation has all multiples of '2'. Divide by 2
---> x +3y = -6
2nd equation has multiples of 5. Divide by 5.
---> x - y = 2
Now elimination part is easier.
Eliminate 'x' variable by subtracting 2nd equation from 1st.
x + 3y = -6
-(x - y = 2)
----------------------
4y = -8
Solve for 'y'
4y = -8
y = (-8)/4 = -2
Substitute value for 'y' back into 2nd equation:
x - (-2) = 2
x + 2 = 2
x = 0
Solution to system is:
x=0, y =-2
You can just do rise over run to find the slope or use the slope equation which is
3=x1
0=x2
5=y1
-1=y2
input those and you can get the slope graphed.
