Answer:
see the explanation
Step-by-step explanation:
Let
s ----> the number of students on the trip
t ----> the number of teachers on the trip
we have the equation
This linear equation represent a proportional relationship, because the line passes through the origin
The constant of proportionality is equal to the slope of the line
so
That means -----> there are a ratio of 25 students by teacher in the trip
or
The number of students is 25 times the number of teachers in the trip
Lets say that J is for Jennys messages, B is for Boris’ and E is for Erics (or Ericas?).
79 = J + B + E
J = E - 6
B = 3E
Since both Jenny’s and Boris’ number of text messages has some kind of relation to Eric’s number of messages, we can say that:
79 = E - 6 (Jenny) + 3E (Boris) + E (Eric), so:
79 = E - 6 + 3E + E /combine like terms
79 = 5E - 6 /add 6 to both sides
79 + 6 = 5E /switch sides + combine like terms
5E = 85 /divide both sides by 5
E = 85/5
E = 17
So, Eric sent 17 messages. Lets get back to those equations we made for Jenny and Boris:
J = E - 6 = 17 - 6 = 11
B = 3E = 3 * 17 = 51
And we can check if it adds up: 51 + 11 + 17 = 79, which is what we were supposed to get.
Multiplicity 2 means you're using that same root twice. So we will FOIL out (x+1)(x+1)(x-3). Doing that multiplying gives us
. Combining like terms gives us the third degree polynomial we are looking for:
Answer:
2/6
Step-by-step explanation:
There are 6 sides, and two are green. That makes it 2/6
