Answer:
None
Step-by-step explanation:
Let's attempt to solve the equation, and see what happens:
-2(3x-1) = -6x -1
-6x +2 = -6x - 1 (expanding the brackets).
2 = -1 (cancelling out the -6x term from each side).
So, since 2 = -1 is not true, this means there are no solutions to this equation.
Answer:
If you know what the formula y = mx +b is, then you know that mx is the slope and b is the y-intercept.
Let`s suppose the equation is y = 2x + 1. The line should be intersecting with the coordinate (0, 1) on it`s way across.
The y axis will ALWAYS be the vertical line. Whatever coordinate the line crosses on the y-axis is the y-intercept.
The y-intercept can also be a negative number.

Answer:
The value of x = 4
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle x
Here the ray cuts the angle into half.
Since the total of the angle was 120, half of this would be 120/2 = 60
Now, it is this value of 60, that our new angle equals to
Mathematically;
3x + 48 = 60
3x = 60-48
3x = 12
x = 12/3
x = 4
This problem is accompanied by a figure.
You can infere these relationships from the figure
(x-5)° = 74° => x = 74 + 5 = 79°
(x-5)° + 58° + (y-1)° = 180 ° => 74 + 58 + y-1 = 180 =>
y = 180 + 1 - 58 - 74 = 47°
Answer: x = 79°, y = 47°. This is the option d)
