The sum of the vectors is (2,1)
A vector exists as an object that has both a magnitude and a direction. Geometrically, we can imagine a vector as a directed line segment, whose length exists the magnitude of the vector and with an arrow suggesting the direction. The direction of the vector exists from its tail to its head.
(-1,-4) + (3,5)
( -1+3 , -4+5 )
( 2,1)

Answer:
Step-by-step explanation:
Good evening
-x(6x-7)
= (-x)(6x-7)
Distribute
(-x)(6x)(-x)(-7)
= -6x²+7x
I hope that's help !
Leah'sdog weighed 14 pounds and Darlene'sdog weighed 70 pounds.
We have,
Let's represent the weight of Leah's dog as 'x' pounds.
According to the given information,
Darlene's dog weighed 5 times as much as Leah's dog, so the weight of Darlene's dog can be represented as '5x' pounds.
Together, the dogs weighed 84 pounds, so we can set up the equation:
x + 5x = 84
Combining like terms, we have:
6x = 84
To solve for x, we divide both sides of the equation by 6:
x = 84 / 6
x = 14
Therefore,
Leah's dog weighed 14 pounds.
To find the weight of Darlene's dog, we substitute the value of x back into the equation '5x':
5x = 5 * 14 = 70
Therefore,
Darlene's dog weighed 70 pounds.
Thus,
Leah'sdog weighed 14 pounds and Darlene'sdog weighed 70 pounds.
