Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL

(3-2i)(1+7i)

3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers

3+19i+14

17+19i or C

Consider this exponential equation:

ioda

Step-by-step explanation:

F( x ) = 5 (3) ^ x

Y intercept

Let x = 0

f(0) = 5× 3 ^ 0

f(0 = 5 × 1

f(0) = 5

X intercept

let y = o

0 = 5 × 3 ^x

No x intercept/ zero

therefore

Vertical intercept (0; 5)

What is t+1/5=t+7/8? What is the value of t? There should be 2 values and the slashes are fractions

muminat

There is NO solution.

Cancel t on both sides (1/5 = 7/8).

Since 1/5 = 7/8, that doesn't make any sense so that is inapplicable ( So NO answer).
