Answer:
C
Step-by-step explanation:
Answer: The correct option is A.
Explanation:
The given equation is,

Multiply both sides by 2.
![2[4(x+5)-5]=\frac{8x+18}{2}](https://tex.z-dn.net/?f=2%5B4%28x%2B5%29-5%5D%3D%5Cfrac%7B8x%2B18%7D%7B2%7D)



Subtract both sides by 8x.

This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
Answer:
y = - 2x - 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 2) and (x₂, y₂ ) = (1, - 8)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 2), then
- 2 = 4 + c ⇒ c = - 2 - 4 = - 6
y = - 2x - 6 ← equation of line
You set it up like this.
It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
