Answer:
2(x - 2)
Step-by-step explanation:
Multiplying as indicated,
2x - 1 - 3 = 2x -4 or 2(x - 2)
( 6 − 7 i ) ( − 8 + 3 i )
First FOIL:
( 6 − 7 i ) ( − 8 + 3 i ) = -48 + 18i + 56i -21i^2
Combine like terms
= -48 + 74i -21i^2
Convert i^2 = -1
= -48 + 74i -21(-1)
And simplify
= -48 + 74i + 21
= -27 + 74i
Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one. Adding 0.6r to both sides makes the coeff. of r a positive one: 0.6r greater than or equal to 2.9+1.3.
0.6r then is equal to or greater than 4.2. Divide both sides by 0.6 to isolate r:
r greater than or equal to 7.
Let r be represented by the horizontal number line. Darken r = 7 and also darken the r axis to the right of r=7.
Answer:
1. 14
c. FD=ED
Step-by-step explanation:
1. 3x+28=5x -3 from both sides get:
25=2x Divide both sides by 2 and get
x=14
