Answer:
see explanation
Step-by-step explanation:
Using 
= i, then i² = ( )² = - 1
and i³ = i² × i = - 1 × i = - i
also
= i² × i² = - 1 × - 1 = 1
We can surmise that i raised to any multiple of 4 will equal 1
Given
( note 35 = 32 + 3 and 32 is a multiple of 4 ), thus
= 
= 1 × i³ = - i
Answer:
y=2x-2
y=3x+1
Step-by-step explanation:
To solve this I will be using the point slope formula
It is as follows
y-y₁=m(x-x₁)
We can choose any m value so I will be choosing m=2
(x₁,y₁) will be (-3,-8) respectively because all we want is for the line to pass through that point
so we have
y-(-8)=2(x-(-3)
We can simplify this to
y+8=2(x+3)
y+8=2x+6
y=2x-2
We then repeat this process but choose a new m (the m value doesn't really matter as long as it's not 0)
I will choose 3
so we have
y-(-8)=3(x-(-3))
Which gives u
y+8=3(x+3)
y+8=3x+9
y=3x+1
for number 7 on the paper is 450 over 300 and answer is 750 over 1 thats how the teachers tought me.

Answer:
Step-by-step explanation:
Using the least common denominator, we have ...
The values of a and b are ...
a = 3
b = -18
Hey there!
So, first, you need to rearrange the second equation so y is in front.
x+y=10
Subtract x.
y=10-x
Plug that in for y.
2x+3(10-x)=45
2x+30-3x= 45
Subtract 30 on both sides.
-x= 15
Divide by -1 on both sides.
x=-15.
I hope this helps!
