Answer:
-7c
Step-by-step explanation:
1,35 3,57
slope = (57 - 35)/(3 - 1) = 11
y = 11 x + b
35 = 11 (1) + b
b= 24
y = 11x + 24
y = 11(5) + 24 = 79
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
