ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
Answer:
-1
Step-by-step explanation:
i is √-1
i^2 is -1
i^3 is -i
i^4 is 1
This cycle repeats itself every 4 powers
so i^6 is -1
Answer:
p + 45 < 89
Step-by-step explanation:
The sum of something is the result of addition so you know that they are adding p and 45 together. They then state that p plus 45 must be less than 89. You can show that by using the less than symbol "<"
If you want to find all of the different values that P could equal then all you have to do is subtract 45 from both sides so the equation would be
p < 44
this means that p can equal anything less than 44 for this statement to be valid. Hope this helped!
