Answer:
Below
Step-by-step explanation:
● 3 ( -x +2x - 1) = x - 1
● 3 ( -x -1 ) = x - 1
● -3x -3 = x - 1
Add -x to both sides
● -3x -3 - x = x -1 -x
● -4x -3 = -1
Add 3 to both sides
● -4x - 3 + 3 = -1 + 3
● -4x = 2
Divide both sides by -4
● -4x/-4 = 2/-4
● x = -1/2

Answer: y = -
x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = -
x - 6
Answer:
B
Step-by-step explanation:
∠ACE and ∠ECB form a straight angle whose sum = 180°, hence
2x + 2 + 5x + 3 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25 → C
Answer:
in this case you can use protector also but
there is another way
Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06
