Answer:
x=-7/9
Step-by-step explanation:
To solve this equation we would consider the bracket first according to BODMAS rule
B ..... Bracket open
O........ Of
D,............. Division
M............. Multiplication
A.............. Addition
S............. Subtraction
So, from the question
-3( x +3) = 3(x+1)-5
-3x -9 = 3x + 3 - 5
Collecting like terms
-3x -3x = 3-5+9
-9x= 7
Dividing both sides by -9
-9x/-9= 7/-9
x=-7/9
Answer:
36
Step-by-step explanation:
180-126=54 Since two angles are supplimentary if they both add up to 180, and 90-54=36 since two angles are complementary if they add up to 90.
Answer:
Plug it into geogebra. The answer should be c.
Step-by-step explanation:
The coefficient of x in the equation of the given line, 3, is its slope. The slope of the perpendicular line is the negatve reciprocal of that, -1/3. You now have the slope and a point on the perpendicular line, so you can write its equation using the point-slope form:
y = m(x -x₁) +y₁
where m is the slope and (x₁, y₁) is the point.
An equation for your perpendicular line is
y = (-1/3)(x -(-1)) -3
y = (-1/3)x -10/3
The slope-intercept form of the equation of the perpendicular line is ...
y = (-1/3)x -10/3
