3(2b + 3)² = 36
Divide both sides by 3.
3(2b + 3)² / 3 = 36/3
(2b + 3)² = 12
Take the square root of both sides.
√(2b + 3)² = √12
(2b +3) = +√12 or -√12
Solving when:
2b + 3 = +√12 2b + 3 = -√12
2b = √12 - 3 2b = -√12 - 3
b = (√12 - 3)/2 √12 ≈ 3.46 b = (-√12 - 3)/2
b ≈ (3.46 - 3)/2 b ≈ (-3.46 - 3)/2
b ≈ 0.46/2 b ≈ -6.46/2
b ≈ 0.23 b ≈ -3.23
Therefore b ≈ 0.23 or -3.23
Hope this helps.
Answer:
1. Equation: 
2. Total pay if Henry sells 27 copies: 
Step-by-step explanation:
1. The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
According to the information given in the exercise, his base salary is $2,100. So you can identify that:
Since he makes an additional of $90 for every copy of he sells, you can identify that:
Therefore, the equation that represents this situation is:
2. If he sells 27 copies, then:
Substituting this value into the equation, you get that his total pay would be:

N represent the number of rides each of them took
entrance fee for both of them = 2x
Total cost of rides = 2n x 3.50 = 7n
The total cost is 44
2x + 7n = 44 (Answer E)
2x + 7n = 44
2(x + 3.5n) = 44 (Answer C)
