Answer:
a. m<CBA = m<DBA because of the definition of an angle bisector (angle bisector cuts the angle in half) We are also told that segment BD and Segment BC are congruent.
We don't know if segment AC and AD are congruent so we can't say those angles (the other two) are congruent.
b. point A and B will stay fixed because they are colinear to segment AB (on the same line)
c. Those two are needed because If those are true we can prove that they are congruent by SAS (Side Angle Side)
d. the reflection an prove that the lines and angles are congruent.
Answer:
The numbers are -15 and 100
![\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7B-15%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7B100%7D)
Step-by-step explanation:
we have
![\frac{2}{10} +\frac{x}{100} =\frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7Bx%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7By%7D)
Solve the left side
![\frac{2}{10} +\frac{x}{100} =\frac{20+x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7Bx%7D%7B100%7D%20%3D%5Cfrac%7B20%2Bx%7D%7B100%7D)
so
![\frac{20+x}{100}=\frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B20%2Bx%7D%7B100%7D%3D%5Cfrac%7B5%7D%7By%7D)
equate the numerators and the denominators
20+x=5 ------> x=5-20=-15
100=y -------> y=5
therefore
The numbers are -15 and 100
![\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7B-15%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7B100%7D)
Each side is 50ft.
[50 x 50 = 2500]
Answer:
(0, -1), (1, 0), (2, 1)
Step-by-step explanation:
I find this easier to do after multiplying the equation by -1:
y = x - 1
Pick any value for x, then subtract 1 from it to find the corresponding value of y.
