Answer:
the domain is that x is a set of real numbers.
the range is y ≤ -3
Step-by-step explanation:
y = -|x + 3|
y is either positive or equal to zero.
Now, x is all real numbers because any value of x used will yield a valid value of y.
Thus, we can say that the domain is that x is a set of real numbers.
Now, for the range:
The minus sign in front of the absolute value indicates that the function has a maximum value.
Thus, the range is y ≤ -3
Answer:
the answer for this questionis 93(68+7)
Answer:
The reason why linear pairs and vertical angles are used to prove lines are parallel is because they area transversal drawn through the parallel lines will form angles on each of the two parallel lines including;
1) Supplementary linear pairs and
2) Vertical angles
3) Alternate angles
Given that either;
a) The corresponding angles that form the linear pairs are congruent
b) The corresponding vertically opposite angles are congruent
c) The corresponding alternate angles are congruent, we have;
The two lines are said to be parallel.

Here's the equation,please do ask if you don't understand. Sorry for my terrible hand writing ^^; hope it helps!
Answer:
- an = 160·0.85^(n-1)
- $51.29
Step-by-step explanation:
In the given formula, a1 refers to the first term of the sequence (160), and r refers to the common ratio (136/160 = 0.85). Putting these values into the formula gives ...
a) Explicit formula: an = 160·0.85^(n-1)
__
b) The 8th term is found by putting n=8 into the formula and doing the arithmetic:
a8 = 160·0.85^(8-1) ≈ 51.29
After 8 months, the price is predicted to be $51.29.
