Answer:
Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is
13x - 4y = 84.
Step-by-step explanation:
Given:
Let,
point A( x₁ , y₁) ≡ ( 4 ,-8)
point B( x₂ , y₂) ≡ (8 , 5)
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula
Substituting the given values in a above equation we get
Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is
13x - 4y = 84.
The angle between w and u is approximately
Step-by-step explanation:
X + 9= 7
get x by itself you -9 on both sides
X + 9 = 7
- 9. -9
X = -2
Let us consider the given expression:
in the scientific notation.
= 
[Using the law of exponents, which states
]
= 
On dividing, we get
= 
Hence, it is the required scientific notation of the given expression.
Answer:
C = 8
Step-by-step explanation:
So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:
C - 12 = -4
C - 12 + 12 = -4 + 12
C = 8
