X+2y=2 …(1)
x-2y=-2…(2)
(1)-(2): (x+2y)-(x-2y)=2- (-2)
4y=4
y=1
subs y=1 into(1)
x+2(1) =2
x=0
so x =0 y=1
the answer is C
Answer:
-12 3/5
Step-by-step explanation:
-4 3/10 - 8 3/10
The signs are the same so we add and then take the sign
4 3/10 + 8 3/10
Add the whole numbers
4+8 = 12
Add the fractions
3/10 + 3/10 = 6/10
Simplify the fraction
6/10 = 3/5
Put them together
12 3/5
Add the sign
-12 3/5
Well 57+59+61= 177 so the answer is 57
Answer:
2 + 3i, midpoint is (2,3)
Step-by-step explanation:
we need to find the midpoint between (-1+9i) and B=(5-3i)
To find the midpoint of two points (a+bi) and (c+di) in a complex plane,
we apply formula
A = (-1+9i) and B=(5-3i)
Midpoint for AB is
2 + 3i , so midpoint is (2,3)
For question 1. a five sided shape has 540° , so if you add all the sides up you get 479, so then you do 540 - 479, to get 61°, which is x
so, x° = 61°
