Answer:

you +1 on each side

Step-by-step explanation:

a is 30-1=7

b is 32=8

to get from "a" to "b" you simply add one on both sides

32 - 1 = 7

+ 1 +1

------------------

32=8

The Pythagorean theorem states that a² + b² = c² for a right triangle with leg lengths, a and b, and hypotenuse length, c.
Jet001 [13]

Answer:

Step-by-step explanation:

Draw the third point at (0, 0). This would make the distance from (3,0) to (0,0) equal to 3, and the distance from (0,4) to (0,0) be 4.

Michael cuts a piece of wood for a project. The first cut is shown and can be represented by the equation . The second cut needs
Verdich [7]
Short Answer: A
Remark

The second cut is going to have the same slope as the original line. The lines are parallel.

Step One
You need to find the slope. That is the main part of this problem. You can pick any 2 points on the graph to do that.

<em>Point one</em> 
(- 11, 10) That point is on the upper left of the line

<em>Point Two</em>
The y intercept is a handy point in this question. It is right on the y axis. Each square counts as 2, so it is at (0,6)

<em>Formula</em>
slope = m = (y2 - y1) / (x2 - x1)

<em>Givens</em>
y2 = 10
y1 = 6
x2 = -12    Each square counts as 2 in the x direction.
x1 = 0

<u>Substitute and solve.</u>
m = (10 - 6) / (-12 - 0)
m = 4/ - 12
m = - 1/3

Step Two
Find the y intercept of the new line using the given point. 

So far what we have is  
y = (-1/3)x + b
The point used for the second line is (0,-2)
-2 = (-1/3)*0 + b 
b = - 2

Answer
The second line is
y = (-1/3)x - 2

A report states that the mean household income last year for a certain rural county was $46,200 and the median was $54,500. If a
Masja [62]

Answer:

skewed to the left

Step-by-step explanation:

A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.

If the mean is greater than the median, the histogram would be skewed to the right

If the mean is less than the median, the histogram would be skewed to the left.

The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left
