Elimination method - -4x = 4y<br> 4x - 8y = 12
nika2105 [10]

Answer: (4,-4)

y=-4, x=4

Step-by-step explanation:

-4x=4y

4x-8y=12

-8y=-4x+12  Now I can substitute -4x for 4y

-8y=4y+12

-2y=y+12

-3y=12

y=-4

-4x=4y

-4x=4(-4)

x=4

Simplify the given expression below 4/3-2i
ANTONII [103]
So-called simplifying, really means, "rationalizing the denominator", which is another way of saying, "getting rid of that pesky radical in the bottom"


\bf \cfrac{4}{3-2i}\cdot \cfrac{3+2i}{3+2i}\impliedby \textit{multiplying by the conjugate of the bottom}&#10;\\\\\\&#10;\cfrac{4(3+2i)}{(3-2i)(3+2i)}\implies \cfrac{4(3+2i)}{3^2-(2i)^2}\implies \cfrac{4(3+2i)}{3^2-(4i^2)}\\\\&#10;-------------------------------\\\\&#10;recall\qquad i^2=-1\\\\&#10;-------------------------------\\\\&#10;\cfrac{4(3+2i)}{3^2-(4\cdot -1)}\implies \cfrac{4(3+2i)}{9+4}\implies \cfrac{12+8i}{13}\implies \cfrac{12}{13}+\cfrac{8}{13}i

A cylinder has a base radius of 4m and a height of 6m. What is its volume in cubic m,
BlackZzzverrR [31]

Answer:

301.4

Step-by-step explanation:

Volume of a cylinder=pi*r^{2}*h.  Assuming you want 3.14 for pi, we can substitue the 4m for r, 6 for h and 3.14 for pi.

V=3.14*4^{2}*6

V=301.44

Since you want to round to nearest tenths, the answer is 301.4
