HELLO? HELLO? ANYONE THERE TO ANSWER

Svetach [21]

Answer:

-2u + w ⇒ answer B

Step-by-step explanation:

* To solve this problem you must find the result from the graph

- The ray move from the origin 6 units to the left and then 1 unit up

∴ The result is <-6 , 1>

* Now lets check which answer give the same result

∵ u = <5 , -5> , v = <1 , -4> , w = <4 , -9>

# Answer A: w - 2v

∵ w = <4 , -9>

- Find 2v by multiply v by 2

∵ 2v = 2<1 , -4> = <2 , -8>

- Subtract 2v from w

∴ w - 2v = <4 , -9> - <2 , -8> = <(4 - 2) , (-9 - -8)> = <2 , -1> ≠ <-6 , 1>

# Answer B: -2u + w

∵ u = <5 , -5>

- Find -2u by multiply u by -2

∵ -2u = -2<5 , -5> = <-10 , 10>

- Add -2u and w

∵ w = <4 , -9>

∴ -2u + w = <-10 , 10> + <4 , -9> = <(-10 + 4) , (10 + -9)> = <-6 , 1> = <-6 , 1>

∴ The answer is B

Answer: The required length of each piece of wood is or 9 inches.

Step-by-step explanation: Given that a piece of lumber is feet long is to be cut into 3 equal pieces.

We are to find the length of each piece of wood in feet and in inches.

We will be using the UNITARY method to solve the given problem.

The length of 3 pieces of wood is equal to

Therefore, the length of each piece of wood will be

Thus, the required length of each piece of wood is or 9 inches.

Convert 14x + 6y = 36 to slope intercept form.

zubka84 [21]

Answer:

y = - $\frac{7}{3}$ x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

14x + 6y = 36 ( subtract 14x from both sides )

6y = - 14x + 36 ( divide all terms by 6 )

y = - $\frac{14}{6}$ x + 6, that is

y = - $\frac{7}{3}$ x + 6 ← in slope- intercept form
