Which complex number is equivalent to (5 + 12i) − (9i2 − 6i), where i = <br> −1<br> ?

Alchen [17]

Answer:

14 + 18i

Step-by-step explanation:

$(5 + 12i) - (9 {i}^{2} - 6i) \\ = (5 + 12i) - (9 \times (- 1) - 6i) \\ = (5 + 12i) - ( - 9 - 6i) \\ = (5 + 12i) + ( 9 + 6i) \\ = 5 + 12i + 9 + 6i \\ \red { \bold{ = 14 + 18i}}$

Express each equation in slope-intercept form. -2x+4y=68, 13x+4y=284

lara31 [8.8K]

To get the answer we have to tranform into y=ax+b form
-2x+4y=68 /+2x
4y=2x+68 /:4
y= $\frac{1}{2} x+17$ - its the result

13x+4y=284 /-13x
4y=-13x+284 /:4
y= $- \frac{13}{4}+ 71$
y=- $3 \frac{1}{4}x+71$ - its the result

It takes 42 cherries to make a cherry pie. If a chef bought 444 cherries, the last pie would need how many more cherries?

jeka94

It takes 42 cherries to make a cherry pie.
If a chef bought 444 cherries and you would like to know how many more cherries would the last pie need, you can calculate this using the following steps:

444 / 42 = 74 / 7 = 10 4/7 pies

4/7 * 42 = 24 cherries

42 - 24 = 18 more cherries

Result: The last pie would need 18 more cherries.
