Mathematics
1 answer:
Andru [333]3 years ago
8 0

Answer:

- 20 + 8i

Step-by-step explanation:

Noting that i²  = - 1

Given

[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket

= ( 6i + 9 + 4i - 5 ) × 2i

= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i

= 20i² + 8i

= 20(- 1) + 8i

= - 20 + 8i

F(x)-mx+ b, f(-2)=3 and f(4)=1 , what is the value of m and b
NeX [460]

Answer: m=\dfrac{-1}{3}, b=\dfrac{7}{3}

Step-by-step explanation:

Given

Function is  f(x)=mx+b

f(-2)=3

\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)

f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)

from (i) and (ii) we get

m=\dfrac{-1}{3}, b=\dfrac{7}{3}
