-7 + 6i - 14i+ 12i^2

-7 - 8i - 12

-19 - 8i

What is Yx6 for Y=2/3

Karolina [17]

Well, it would be 2/3 x 6, which you could 2/3 x 6/1 and then it would be 12/3 which would equal 4. This can also be proven through inspection, since 2/3's of 6 is 4 because 1/3 of 6 is 2.

The point-slope form of a line that has a slope of –2 and passes through point (5, –2) is shown below.

Leviafan [203]

Answer:

y = -2x +8

Step-by-step explanation:

One way to write the equation of a line with slope m through point (h, k) in point-slope form is ...

y = m(x -h) +k

In this form, the equation of the line is ...

y = -2(x -5) -2

Eliminating parentheses and collecting terms puts this in slope-intercept form:

y = -2x +8

What are the excluded values v^2 +1 / v^2 -v-6

valentina_108 [34]

The rational expression
$\dfrac{v^{2}+1}{v^{2}-v-6}=\dfrac{v^{2}+1}{(v-3)(v+2)}$
will be undefined where the denominator is zero. Values of v that make the denominator zero are v=3 and v=-2.

Excluded values of v are -2 and 3.
