21x - 19 = 3x + 17 |add 19 to both sides
21x = 3x + 36 |substract 3x from both sides
18x = 36 |divide both sides by 18
x = 2
The answer is e = -2

Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
2e + 4 = 2 • (e + 2)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : e+2 = 0
Subtract 2 from both sides of the equation :
e = -2
Answer:
(-2,-6) (6,2)
Step-by-step explanation:
Answer:
B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:
Where
MD=60
n=9
df=n-1=8
Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)
C I think because vertical lines is (VUX) which is Vertical, undefined slope, and x=
