ight what do i gotta answer tho
Answer:
(4,-4)
Step-by-step explanation:
3*(6x+5y=4)
18x+15y=12
-) 18x – 4y = 88
19y = -76
y=-4
plug back into first equation
6x + 5(-4) = 4
6x = 4+20
x=4
Step-by-step explanation:
1. 3x + 4 = 19
3x = 15
x = 5
2. 7 + 2x = 15
2x = 8
x = 4
The values of tan x is undefined for odd number multiples of x.
Thus, the values of tan x is undefined for x = . . . -3(90), -1(90), 1(90), 3(90), . . .
Therefore, the values of x for which tan (x) is undefined are <span>-270°, -90°, 90°, and 270°</span> [option A].
