Answer:
Step-by-step explanation:
a(1) = -7 (given)
a(2) = a(1) + 4 = -7 + 4 = -3
a(3) = a(2) + 4 = -3 + 4 = 1
a(4) = a(3) + 4 = 1 + 4 = 5
and so on.
Answer:
±3i
Step-by-step explanation:
Given the value ±√-9, we are to express the value using the imaginary number 'I'
±√-9 = ±√9×-1
= ±√9 × √-1
In complex number, √-1 = i
The expression becomes;
±√9 = ±3 × i
±√9 = ±3i
Hence the value in simplified form is ±3i
Y=3x-5 and passes through the point 5,10 should be 56
Answer:
0.1 or if u want it as a fraction 1/10
Step-by-step explanation:
the equations
1/4=2x and 1/4/x=2have the same solution
because 1 / 4/ x = 2 can be simplified to
1 / 4 = 2x which is the same with the first equation
Solve for x = 1/8
Then substitute it to the both equation
¼ = 2 ( ¼)
¼ = ¼
2nd equation
1/ 4 /( 1/8) = 2
2 =2
