Answer:
m perpendicular = - 3
Step-by-step explanation:
To start with, we need to find the slope of the given line, by solving for y in the equation
x - 3 y = 12
x = 3 y + 12
x - 12 = 3 y
divide by 3 both sides:
y = x/3 - 12/3
y = (1/3) x - 4
then, the slope of the given line is 1/3, and according to the property of perpendicular lines, a perpendicular slope will be the 'opposite of the reciprocal" of the slope of the original line. That is: the value - 3.
Then the slope of the perpendicular line is: m = - 3.

O A. The slope of the line is (Type an integer or a simplified fraction)
OB. The slope of the line is undefined
Answer:
The slope of the line is zero because there is no change in y or x

9(x6)=207
answer it step by step
Answer: x=1.686377,−1.686377
Step-by-step explanation:
9x6=207
Step 1: Divide both sides by 9.
9x6/9=207/9
x6=23
Step 2: Take root.
x=±(23)(16)
x=1.686377,−1.686377

The box-and-whisker plot corresponds to this distribution is A.
What is Box plot?An illustration of variation in a set of data is called a box and whisker plot. A histogram analysis usually gives an adequate display, but a box and whisker plot can add more detail while enabling the display of different sets of data on the same graph.
We have, The distribution of the gas mileage of a fleet of cars.
From the data,
Minimum value = 28
lower quartile = 29
Median= 30
Upper quartile = 31
Maximum value = 32
Here the box plot represent the above parameters in box plot A.

Answer:
1. see the first attachment for a graph; quadrants I, II, III; vertex (-3, -4); x-intercepts -5, -1; graph is dashed line, shaded inside the parabola, which opens up
2. see the second attachment for a graph; all quadrants; vertex (1, 2); x-intercepts 1±√2; graph is a solid line, shaded outside the parabola, which opens down; (-7, 0) is a solution
Step-by-step explanation:
1. The boundary expression is in vertex form, so the vertex can be read directly.
y = (x -h)^2 +k . . . . . . parabola with vertex (h, k)
y > (x +3)^2 -4 . . . . . (h, k) = (-3, -4)
The leading coefficient is +1, a positive number, so the parabola opens up. The relation is y > ( ), so values of y above the dashed line will be shaded. Those values are inside the parabola. The points (0, 0) and (-7, 0) are not in the shaded area, so are not solutions.
__
2. Again, the boundary expression is in vertex form, so the vertex can be read directly.
y ≥ -(x -1)^2 +2 . . . . . (h, k) = (1, 2)
The x-intercepts are found by solving for x when y=0:
0 = -(x -1)^2 +2
x -1 = ±√2
x = 1±√2
The leading coefficient is -1, so the parabola opens downward. The relation is y ≥ ( ), so y-values above the solid line will be shaded. Those values are outside the parabola. Point (0, 0) is not a solution. Point (-7, 0) is a solution.
_____
Additional comment
As with the graph of any inequality, the boundary line is solid when the "or equal to" case is part of the relation. If the relation is strictly "greater than" or "less than", then the boundary line is dashed.

Write and solve an equation to find the value of x and the missing angle measures.
Answer:
x = 11 --> angles = 95 degrees
Step-by-step explanation:
They are equal to each other so
7x + 18 = 8x + 7
Put the like terms together
18 - 7 = 8x - 7x
11 = x
so when we substitute this value of x into the equations, we get that both angles are 95 degrees.

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The numbers are,
⇒ 4.091 and 2.174
Now,
Since, The numbers are,
⇒ 4.091 and 2.174

evaluate the absolute value expression for x= -3 and y= -6
Answer:
-4
Step-by-step explanation:
So we are given the expression: | y - x | + y - 1, and we have our values for (x,y): (-3,-6).
So, we can just start plugging things in and simplifying, so:
| -6 + 3 | - 6 - 1 = | -3 | -7
