2 sin squared x= 4 sinx+6

Mathematics
1 answer:
mote1985 [20]3 years ago
8 0

Answer:

x = 3π/2 + 2πk

Step-by-step explanation:

2 sin² x = 4 sin x + 6

2 sin² x − 4 sin x − 6 = 0

sin² x − 2 sin x − 3 = 0

(sin x − 3) (sin x + 1) = 0

sin x − 3 = 0

sin x = 3

no solution

sin x + 1 = 0

sin x = -1

x = 3π/2 + 2πk

Solve for . 5w-26=-4(w-7) Simplify your answer as much as possible. PLZ HELP
NikAS [45]

Answer:

w = 6

Step-by-step explanation:

5w-26 = - 4 (w - 7)   multiply -4 through

5w - 26 = - 4w + 28  add 4w to each side to cancel it out on the right

5w + 4w - 26 = 28  

9w - 26 = 28  Now add 26 to each side

9w - 26 + 26 = 28 + 26

9w = 54   Now divide each side by 9

(9w)/9 = 54/9

w = 6

x= 1, 2, 3, 4, 5. y=11\4, 25\4, 39\4, 53\4, 67\4. what equation relates y to x in the values x and y?
larisa86 [58]
(1,11/4)(2,25/4)
slope = (25/4 - 11/4) / (2 - 1) = (14/4) / 1 = 14/4 = 7/2

y = mx + b
slope(m) = 7/2
(1,11/4)...x = 1 and y = 11/4
now we sub and find b, the y int
11/4 = 7/2(1) + b
11/4 = 7/2 + b
11/4 - 7/2 = b
11/4 - 14/4 = b
-3/4 = b

so ur equation is : y = 7/2x - 3/4
