x = negative 7 plus-or-minus 4 StartRoot 6 EndRoot i
x = –7 ± 8i
x = 7 plus-or-minus 4 StartRoot 6 EndRoot i
x = 7 ± 8i

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

77

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

b is the right answer
