2x + y = - 8
y = - 2x - 8
Since we are looking for a parallel line, we use the same slope of - 2x.
y = - 2x + b
Plug in your given point.
5 = - 2(- 3) + b
5 = 6 + b
5 - 6 = b
-1 = b
Your equation is y = - 2x - 1

Answer:
370
Step-by-step explanation:
The set B∩(F∪M) is the sum of the numbers on line B in both the M and F columns:
B∩(F∪M) = 54 +316 = 370
The set B∩(F∪M) contains 370 respondents.
The real distance between the two cities is 100000 feet.
<h3>How to use scales to estimate real life distances</h3>
Scales are applications of ratios in which maps are mostly based and that are used to estimate real distances between two points. Scales (r) are represented by the following formula:
r = m' / m (1)
Where:
- m - Real length
- m' - Reduced length
If we know that m' = 400 in and r = 4 in / 1000 ft, then the real distance between the two cities is:
m = m' / r
m = (400 in) / (4 in / 1000 ft)
m = 100000 ft
The real distance between the two cities is 100000 feet.

Answer:
y = ax^2 + bx - c
Step-by-step explanation:
The product means multiply
The production cost(y) = computing components (a) * number of devices (x) + product of labour (b) * number of devices (x) - savings on reusable material (c)
Therefore,
y = ax^2 + bx - c
