Answer:
(1,-1)
Step-by-step explanation:
To write it in simplest form, you must find a common factor.
In
, 3 is a factor of both 3 and 9
3÷3=1 and 9÷3=3
So
is your answer in simplest form.
Answer:
multiple choice is worth 2
short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
multiple choice is worth 2
short response is worth 4
Answer:
n = -2 or n = 10
Step-by-step explanation:
n^2 - 8n - 20 = 0
triangles angles always add up to 180° that being said,
41+32=73
180-73=107
angle e= 107°
hope this helps!
