In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis.
y - 4 = -2x - 6
Now you need to move the constant to the right side and change its sign.
y = -2x - 6 + 4
Calculate the sum of -6 + 4.
y = -2x - 2
Since we cannot simplify this down any further,, y is going to equal -2x - 2.
Let me know if you have any further questions.

Answer:
a) (0.576, 0.624)
Step-by-step explanation:
Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%
α = 1 - C = 1 - 0.85 = 0.15
α/2 = 0.075
The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence 
The margin of error (E) is:

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
Answer:
yes
Step-by-step explanation:
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
