X +y = 5
x = 5-y
---------------------
2x -y = 1
2•(5-y) -y = 1
10 -2y -y = 1
10 -3y = 1
-3 y = 1-10
-3y = -9
then you can divide it
y = -9/-3
y= 3
for x :
x + y = 5
x + (3) = 5
x= 5-3
x= 2
(x,y)
(2,3)
Answer:
True
Step-by-step explanation:
This is true because it crosses the x-axis. (x,y)
The pattern is adding 1.43 to the term before
1.11 + 1.43 = 2.54 + 1.43 = 3.97 + 1.43 = 5.40 . . .and so on.
Just plug in the square root of 100 in your calculator (10) and then either leave it as 10/49 or simplify it to a decimal...depending on what your teacher is expecting from you.
Answer:
Option C) Angle 6 and 7 only
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
So here the angle supplementary to Angle 5 would be 6, since adding both would get us 180 degrees. Then there's angle 7 which would also give us 180 degrees when added to angle 5.
