Answer: C
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
substitute the values from the replacement set into the left side of the equation to find which values of x make it true.
x = - 21
14 - 2(- 21) = 14 + 42 = 56 ≠ 28 ← False
x = - 7
14 - 2(- 7) = 14 + 14 = 28 ← True
x = 7
14 - 2(7) = 14 - 14 = 0 ≠ 28 ← False
Thus x = - 7 is the solution
Answer:
x= 7.1
Step-by-step explanation:
use sine because x is the opposite and 10 is the adjacent
set up your equation:
sin(45)= x/10
multiply both sides by 10:
10(sin(45))= (x/10)10
10(sin(45))= x
multiply 10 by sin(45):
7.1=x
