Answer:

Option B k > 0

Step-by-step explanation:

we know that

Observing the graph

The slope of the line is positive

The y-intercept is negative

we have

3y-2x=k(5x-4)+6\\ \\3y=5kx-4k+6+2x\\ \\3y=[5k+2]x+(6-4k)\\ \\y=\frac{1}{3}[5k+2]x+(2-\frac{4}{3}k)

The slope of the line is equal to

m=\frac{1}{3}[5k+2]

Remember that the slope must be positive

so

5k+2> 0\\ \\k > -\frac{2}{5}

The value of k is greater than -2/5

Analyze the y-intercept

(2-\frac{4}{3}k) < 0\\ \\ 2 < \frac{4}{3}k\\ \\1.5 < k\\ \\k > 1.5

1.5 is greater than zero

so

the solution for k is the interval ------> (1.5,∞)

therefore

must be true

k > 0

Prove that (a-b) x (a+b)=2a x b is true.<br> (a and b are vectors)
Anon25 [30]
(a-b) X (a+b)
=  aXa - bXa +aXb -bXb (distributing)

Now, cross product of a vector with itself = 0
so, aXa = 0, bXb = 0

Also, aXb = - bXa

so,
(a-b) X (a+b) = 0 + aXb + aXb + 0
= 2aXb

hence, proved :)

G(x) = 3x − 3; Find g(−6)
atroni [7]

Answer:

The correct answer is -21.

Step-by-step explanation:

To solve this problem, we must plug in -6 for each x in the function.

This is modeled below:

g(x) = 3x - 3

g(-6) = 3(-6) - 3

Now, we must simplify by first multiplying and then adding the remaining terms together.

g(-6) = -18 - 3

g(-6) = -21

Therefore, the correct answer is -21.

Hope this helps!
