Answer:
C. The variable
Step-by-step explanation:
The given value states that all values of x will be replaced by 1. The definition of a variable in algebra is a symbol for a number we don't know yet, so x will be the variable in this equation
Answer:
Step-by-step explanation:
4 3/4 divided by 3/4
= 19/4 ÷ 3/4
= 19/4 ÷ 4/3
= 19/3
= 6 1/3
Answer:
x = 100
Step-by-step explanation:
-100x - 100 = -100x
+100= +100
-100x= -100x + 100
x=100
Answer:
Step-by-step explanation:
tan x = ( sin x ) / ( cos x )
tan²x + 1 = sec²x
sec x = ± √(tan²x + 1)
sec x = 1 / cos x
~~~~~~~~~~~~
tan x = 4 and sin x < 0
cos x - ?
<u><em>If tan x > 0 and sin x < 0 ⇒ cos x < 0</em></u>
sec²x = 16 + 1 = 17 ⇒ cos²x =
cos x = -
