The slope is 2 and the equation of the line is y = mx+b with m =2

Then the equation becomes: y = 2x+b. How to calculate b?
Since this line passes through the point (-3 , 4), we replace x with -3 and y=4

4= 2.(-3) + b 
4 = - 6 + b
and b= 10. The final equation is : y = 2x + 10 (answer a)

Answer:

The value of n is 11 feet.

Step-by-step explanation:

Given that the area of rectangle from is A = length×width so we have to substitute the variables into the formula in order to find n :

area = length \times width

Let area = 33,

Let length = n,

Let width = 3,

33 = n \times 3

3n = 33

n = 33 \div 3

n = 11 \: feet

Find the solution set of each of the following inequations in the given domain.
BARSIC [14]
<h3>Answer:  x ≥ 5</h3>

Since x is a natural number, this is the same as saying x > 4

=======================================================

Explanation:

Let's solve for x

x+12 < 4x-2\\\\12+2 < 4x-x\\\\14 < 3x\\\\3x > 14\\\\x > 14/3\\\\x > 4.667 \ \text{(approximate)}\\\\

Since x \in \mathbb{N}, this means x is a natural number and a value from the set {1,2,3,4,...} aka the set of positive whole numbers. Zero is not in the set of natural numbers.

So we'll need to round that 4.667 to the nearest whole number to get x ≥ 5

If we were to replace x with anything from the set {5, 6, 7, 8, ...}, then that would make the original inequality to be true.

The notation x ≥ 5 and x > 4 are identical when x is a natural number, because we're describing the same solution set of any whole number 5 or larger.
