Vector u has initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and terminal point at

spin [16.1K]

Answer:

⟨-5, -1⟩

Step-by-step explanation:

Vector:

A vector is given by its endpoint subtracted by its initial point.

Vector u has initial point at (3, 9) and terminal point at (–7, 5)

Then

$u = (-7, 5) - (3,9) = (-7 - 3, 5 - 9) = (-10,-4)$

Vector v has initial point at (1, –4) and terminal point at (6, –1).

Then

$v = (6,-1) - (1,-4) = (6-1,-1-(-4)) = (5,3)$

What is u + v in component form?

$u + v = (-10,-4) + (5,3) = (-10+5,-4+3) = (-5,-1)$

⟨-5, -1⟩ is the answer.

3p - 2(p-4) = 7p + 6

Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

$3p-2 (p-4) = 7p + 6$

We apply distributive property on the left side of the equation taking into account that $+*-=-$ and $- * - = +$ :

$3p-2p + 8 = 7p + 6$

We add similar terms:

$p + 8 = 7p + 6$

We subtract $7p$ from both sides of the equation:

$p-7p + 8 = 6\\-6p + 8 = 6$

We subtract 8 from both sides of the equation:

$-6p = 6-8\\-6p = -2$

We divide by -6 on both sides of the equation:

$p = \frac {-2} {- 6}\\p = \frac {1} {3}$

Answer:

$p = \frac {1} {3}$

Clare mixes 2 and one half cups of water with one third cup of orange juice concentrate.

Keith_Richards [23]

Answer:2 1/2 + 1/3 = 5/2 + 1/3 = 15/6 + 2/6 = 17/6 cup

(2/6)/(17/6) = (2/6)(6/17) = 2/17 (two parts in 17), or 11.8%

1 2/3 + 1/4 = 5/3 + 1/4 = 20/12 + 3/12 = 23/12 cup

(3/12)/(23/12) = (3/12)(12/23) = 3/23 (three parts in 23), or 13.04%
