The correct answer is D, because -3 multiplied by -x + 12 is 3x + - 36, which is 3x - 36, which is D
Answer:
Step-by-step explanation:
This might be familiar to you if you know about the pythagorean relationship in right triangle, aka pythagoras's theorem.
It states that, in a right triangle, the sum of the squares of the 2 shorter sides equals the square of the longest side, aka the hypotenuse.
Note that the triangle in this case is a right angled triangle, and all the surrounding shapes are squares.
So by the pythagorean relationship we have,
2^2 + 4^2 = c^2
4 + 16 = c^2
20 = c^2
c = sq root 20 = 2 * sq root 5

Answer:
1. Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
2. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:
![y=2x\\\\x+y=-6](https://tex.z-dn.net/?f=y%3D2x%5C%5C%5C%5Cx%2By%3D-6)
In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,
![x+2x=-6\\\\3x=-6](https://tex.z-dn.net/?f=x%2B2x%3D-6%5C%5C%5C%5C3x%3D-6)
Dividing both sides by 3, we get:
![\frac{3x}{3}=\frac{-6}{3}\\\\x=-2](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B-6%7D%7B3%7D%5C%5C%5C%5Cx%3D-2)
Now, ![y=2x=2\times -2=-4](https://tex.z-dn.net/?f=y%3D2x%3D2%5Ctimes%20-2%3D-4)
Therefore, the solution is (-2, -4)
