Step-by-step explanation:
☆Remember:
☆Slope-intercept:
---
☆We need to find the slope first. So just plug in according to the slope formula!
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
---
☆Now all we need to do is plug in and we are done!

Step-by-step explanation:
Use triangle congruency:
BC=EC, AC=DC - Given
m∠DCE = m∠ACB because they are vertical angles
Therefore ΔABC ≅ ΔDEC because of Side-Angle-Side congruency
AB=DE because corresponding parts of congruent triangles are also congruent (CPCTC)
Answer:
I think it is both first and second
Step-by-step explanation:
108/9=12 is correct
78/5 and 22/5 added together is 100/5 which is 20.
6 4/7 - 4 3/7 cannot be 10 1/7 because you are subtracting not adding.
11/3 is 9 2/3 not 4 1/3
12*9=108 there for 108/9=12
Answer:
x=10, y=-1
Step-by-step explanation:
x-y=11
2x+y=19
3x=30
x=10
10-y=11
-y=1
y=-1
USED ELIMINATION BC THERE WAS ALREADY A Y AND -Y
