Answer:
Option b: (-0.3, -7)
Step-by-step explanation:
If we have two points v = (x₁, y₁) and w = (x₂, y₂)
The vector that connects these two points and starts in point v, is written as:
vector = w - v = (x₁, y₁) - (x₂, y₂) = (x₂ - x₁, y₂ - y₁)
In this case, we want to find the vector that goes from (-3.7,2) to (-4, -5).
Then we will have:
vector = (-4, -5) - (-3.7,2) = (-4 - (-3.7), -5 - 2)
vector = (-0.3, -7)
Then the correct option is b.
I believe the answer would be D.
= 3x + 9x = 6x + 42
= 3x + 9x - 6x = 42 ( transposing +6x from LHS to RHS changes +6x to -6x )
= 12x - 6x = 42
= 6x = 42
= x = 42 ÷ 6 ( transposing ×6 from LHS to RHS changes ×6 to ÷6 )
= x = 7
Let us check whether we have found out the correct value of x or not by placing 7 in the place of x :
= ( 3 × 7 ) + ( 9 × 7 ) = 6 × 7 + 42
= 21 + 63 = 42 + 42
= 84 = 84
= LHS = RHS
Hence proved we have derived the correct value of x .
Therefore , the value of x = 7 .
