Answer:
Step-by-step explanation:
(-7-41)(8-6)
-48*2
-96
This is what I got. I don't see anything in the equation that has "i" in it.
If it is supposed to be (-7-4i)(8-6) foil the problem.
-56+42-32i+24i combine like terms
the answer is -14-8i

Answer:
9 litres of tomato concentrate
Step-by-step explanation:
x = number of true/false questions
y = number of multiple choice questions
x + y = 40
2x + 3y = 144
from the first equation we get
x = -y + 40
this identity we can then use in the second equation
2(-y + 40) + 3y = 144
-2y + 80 + 3y = 144
y + 80 = 144
y = 64
and
x + 64 = 40
x = -24
that does not make any sense.
something is wrong with the problem description.
just think about it :
40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.
but the description says 144 points.
for 144 points we need at least 48 (144/3) questions.
that does not fit.
the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.
You could change the y intercept to something less than positive eight.
