Pythagorean theorem helps us find a sides measurements in a right triangle. the formula is a^2+b^2=c^2<span />
Answer:
A) x + 0
Step-by-step explanation:
In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)
In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)
Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.
Therefore, the rule for x-coordinates = x + 0
Answer: A) x + 0

20x and 9y. Terms can be either a single number or variable. Also, terms are separated by +, - signs. Thus, terms are parts of a mathematical expression separated by + or - signs.
<u>Let's set up some variables</u>:
- b: # of boys
- g: # of girls
<u>Let's set up some equations based on the informative given</u>:
- boys to girls ratio ⇒ 1: 12
(M<em>athematical form)</em> g = 12b
(<em>Mathematical form) </em>g = b + 77
<u>Let's put the equation together</u>:
g = 12b -- equation 1
g = b + 77 -- equation 2
(equation 2)'s value of g into (equation 1)
12b = b + 77
11b = 77
b = 7
There are 7 boys.
<u>Answer: 7 boys</u>

Hope that helps!
