8x - 3x - 7 = 23
5x - 7 = 23
5x = 30
x = 30/5 = 6
If i = √-1 ,
then ...
i² = (√-1)² = -1
i³ = - √-1 = -i <== the answer to the question
i⁴ = (i²) · (i²) = (-1) · (-1) = 1
and then the whole thing starts over again, for higher powers of i .
Answer:
x = 4
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 8 when x = 10
k = yx = 8 × 10 = 80
y = 
← equation of variation
When y = 4, then
4 = ( multiply both sides by x )
4x = 80 ( divide both sides by 4 )
x = 20
To answer this question, the first thing you should know is that if they have the same base, the exponents are added.
We then have to multiply:
-3y (5y ^ 3 + 11y ^ 2 - y + 8) = -15y ^ 4 -33y ^ 3 + 3y ^ 2 - 24y
answer
the MISSING LINEAR Term is
- 24y
Answer:
47 degrees
Step-by-step explanation:
A shape always adds up to 180 so I added the two degrees and subtracted it from 180. You get the answer 47
