The answer is -16 - 10i.
Using the distributive property on the first part, we have:
-2i*7--2i*4i + (3+i)(-2+2i)
-14i+8i² +(3+i)(-2+2i)
Using FOIL on the last part,
-14i+8i²+(3*-2+3*2i+i*-2+i*2i)
-14i+8i²-6+6i-2i+2i²
-10i+8i²-6+2i²
Since we know that i = -1,
-10i+8(-1)-6+2(-1)
-10i-8-6-2
-16-10i

Step-by-step explanation:
Since the concert promoter started with 2
pages of ads but had to cancel 1
, subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:
2

In order to subtract fractions, you need to have like denominators, so you need to convert
into an equivalent fraction with a denominator of '8'. Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
Answer:
Leave em alone or go be noisy?
Step-by-step explanation:
Y = -1x+b
replace x and y to find b
2 = -1*2+ b
b = 4
Final:
y = -1x + 4
