Help……..-What is the rule for the function that is graphed?

klemol [59]

Answer: y = 2x +2
You need to first pick two points from the graph. Then you need to find the slope and plug in one of the original points you used to find the slope into the slope-intercept formula in order to find the b - intercept.

Which fraction do you multiply by to simplify 5/ 4 - 3i ?

Rzqust [24]

So I assume
$\frac{5}{4-3i}$

If so. Let us begin.

$\mathrm{Multiply\:by\:the\:conjugate}\:\frac{4+3i}{4+3i} \ \textgreater \ \frac{5\left(4+3i\right)}{\left(4-3i\right)\left(4+3i\right)} \ \textgreater \ \left(4-3i\right)\left(4+3i\right)$

$\mathrm{Apply\:complex\:arithmetic\:rule}:\ \left(a+bi\right)\left(a-bi\right)=a^2+b^2$
$Where\;a=4,\:b=-3 \ \textgreater \ 4^2+\left(-3\right)^2 \ \textgreater \ Refine \ \textgreater \ 25$

$\frac{5\left(4+3i\right)}{25} \ \textgreater \ \mathrm{Cancel\:the\:common\:factor:}\:5 \ \textgreater \ \frac{4+3i}{5}$

$Group\:the\:real\:part\:and\:the\:imaginary\:part\:of\:the\:complex\:number$
$\frac{4}{5}+\frac{3}{5}i\;is\;our\;answer!$

Hope this helps!

Common core question please help!!!

Maru [420]

She has 648 shirts.

Work:
Lisa has 42 pineapples. 4 + 2 = 6
Johnny has 6 marbles.
42 + 4 + 2 + 6 = 54
54 + 5 + 4 = 63
63 + 6 + 3 = 72
But 72 is a multiple of 6!
Let's go further:
72 * 6 = 432

Now let's look at the word 'shirt'.
The middle letter is I.
I is the 9th letter of the alphabet.
Remember the number 72?
72*9 = 648
