Answer:
Every real number other than zero is either positive or negative. The non-negative whole numbers are referred to as natural numbers (i.e., 0, 1, 2, 3...), while the positive and negative whole numbers (together with zero) are referred to as integers. (Some definitions of the natural numbers exclude zero.)

Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point (x, y) is rotated 90° counterclockwise, its new coordinate is (–y, x).
Give point M (3, –6) is rotated 90° counterclockwise:
Step 1: Interchange the x- and y-coordinates to get (-6, 3)
Step 2: Multiply the new x-coordinate by –1 to get (-6(–1), 3)
Step 3: Simplify to get (6, 3)
Therefore she made an error in step 1
Answer: An error in step one

Select the locations on the number line to plot the points 9/2 and −7/2.
Answers
Answer:To plot these points on the number line, you should label the long lines on the number line as such starting from the left (-5-already there, -4,-3,-2,-1,0,1,2,3,4,5-already there).
Now take each number and convert the improper fraction into a mixed number. 9/2 = 4 1/2 and -7/2 = -3 1/2.
4 1/2 would plotted on the line exactly in between the 4 and 5.
-3 1/2 would be plotted on the line exactly halfway between -3 and -4.
You will draw a dot to show each of these positions on a number line.

Answer:
∠ MDF = 39°
Step-by-step explanation:
∠ MDH = 90°, so
∠ MDF + ∠ FDH = 90 , substitute values
2r + 59 + 6r + 111 = 90 , that is
8r + 170 = 90 ( subtract 170 from both sides )
8r = - 80 ( divide both sides by 8 )
r = - 10
Thus
∠ MDF = 2r + 59 = 2(- 10) + 59 = - 20 + 59 = 39°

Answer:
x should be 11
Step-by-step explanation:
What we know:
The angles shown are 13x + 12, and 2x + 3
The two angles are complementary, which means they equal 180 degrees.
(13x + 12) + (2x + 3) = 180
15x + 15 = 180
15x = 180 - 15
15x = 165
x = 11

z=m-x solve for x
Answers
Answer:
x = m - z
Step-by-step explanation:
z = m - x add x to both sides
z + x = m - x + x
z + x = m subtract z from both sides
z - z + x = m - z
x = m - z
Answer:
-z + m = x
Step-by-step explanation:
z = m-x
subtract the m from both sides
z-m = -x
you can't have a negative x so multiply everything by -1
-1(z-m = -x)
-z + m = x

Answer:
v=12500-2500h
Step-by-step explanation:
Ok so to create this equation all you need to do is look at what information is given. You start with 12500 gallons of water so we know our equation is going to have 12500 in it.
So far our equation would look like this v=12500
The next information we are given is that it is decreasing by 2500 every hour so we know that we are going to be subtracting 2500 based on how many hours have went by so our equation would then look like this.
v=12500-2500h
we can check this by plugging in some numbers to see if it works. So at Zero hours we should still be at 12500
v=12500-2500(0)
v=12500
Ok so we know that it works for zero, but we should check at least one more number. We know that after 3 hours we would of lost 7500 gallons of water so it should equal 12500-7500=5000 gallons. Lets check this in our equation
v=12500-2500(3)
v=12500-7500
v=5000 Gallons

y = -4x - 2
Work: The line crosses the y-axis at -2 making this the y-intercept. To find the slope, you need to take two points from the graph (you already have (0,-2) from the intercept) and put them in the equation:
y(sub 2) - y(sub 1) all over x (sub 2) over x (sub 1). Sub 1 and two just means the order of the points. so if you took the points (-1,2) and (0,-2), the equation would look like:
(-2-2)/(0-(-1)). This gives you -4/1 which is equal to -4. So now you have your y intercept (-2) and your slope (-4) so you put it into slope - intercept form:
y=mx + b where m is slope and b is y-intercept
Answer:
The answer to your question is -4x -2
