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

Which Graph Represents A function ?<br><br> NEED ANSWER ASAP !!!!
ANEK [815]

Answer:

The very last one is a function

Step-by-step explanation:

The last one is a function because there are no y values that repeat. For example, If the points on one graph are like this; (1, 3) (2, 3); then it cannot be a function, the y values cannot repeat if it is a function.

To make things easier, just try to imagine vertical drawing lines through each point in every graph, if this imaginary vertical line passes more than one point in any graph, then that graph is not a function.

I hope this helps!! :D

Decide if the expression is positive or negative. Explain in words how you know, please.
AysviL [449]

Step-by-step explanation:

The first expression is :

-11\times \dfrac{2}{3}

Numerator = -11×2 = -22

Denominator = 3

So, answer will be :

-11\times \dfrac{2}{3}=\dfrac{-22}{3} (negative)

The second expression is:

-11\times \dfrac{-2}{3}

Numerator = -11×-2 = 22

Denominator = 3

So, the answer will be :

-11\times \dfrac{-2}{3}=\dfrac{22}{3} (positive)

Hence, this is the required solution.
