Solve for k. 3.28 = –0.41(k + –5) k =

2 answers:

3.28=-0.41(k+-5)

Distribute your -0.41 to both k and -5.

It will look like this: 3.28=-0.41(k) + -0.41(-5)

You now have 3.28= -.041k+2.05, and have to subtract 2.05 from both sides to try and get k alone.

So, 1.23=-0.41k, now you divide both sides by -.041, because you cannot have a negative x as an answer.

Your answer will be k= -3

The value would be zero (0) bcuz if all ends up being 0 no matter how many zeros then yes it would be 0 as the value

Simplify<br><br> urgent pls

Answer: VI)

$\frac{x - 1}{3(x+ 1)}$

VII)

$\frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

Step-by-step explanation:

VI)

$\frac{{(x + 1)}^{2}}{6} \times \frac{2}{{x}^{2} - 1}$

$= \frac{2{(x - 1)}^{2} }{6(x - 1) \times (x + 1)}$

$= \frac{x - 1}{3(x+ 1)}$

VII)

$\frac{{m}^{2} - 49}{3n} \div \frac{2n - 14}{6}$

$= \frac{(m - 7) \times (m + 7)}{3n} \times \frac{6}{2(n - 7)}$

$= \frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

If the slope is 2 and the line goes through (3,-3) what is the equation?

motikmotik

Answer:

$y = 2x -9$

Step-by-step explanation:

To find the equation of a line using slope and a point, first use the slope to create the basic line using the slope and work from there.

For instance, the base equation here is

$y = 2x$

This line passes through the point (0, 0).

You can then plug in a value for x. In this case, use the value of 3, as it corresponds with your question.

$y = 2 * 3$

A point on the line of y = 2x would thus be (3, 6).

To make the y-value equal -3, you must then subtract from the original equation. There are 9 units between 6 and -3, so you must subtract nine units in the equation. You should get this at the end:

$y = 2x -9$
