You can do addition and substraction operations with polynomials similarly as with simple real numbers.
First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
Answer:
7/12
Step-by-step explanation:
12/12-5/12=7/12
Answer:
C, 17 R4.
Step-by-step explanation:
6x17 is equal to 102, and 102+4 gets you to 106, therefor C is the correct answer.
Answer:
Step-by-step explanation:
I cannot use the line tool for you, but I can rewrite the equations
y = -x + 4 is good enough
Two points for this graph:
x = 0 -> y = 4 gives the point (0, 4)
x = 1 -> y = 3 gives the point (1, 3)
18x + 6y = -6
6y = -18x - 6
y = -3x - 2
Two ponts for this graph:
x = 0 -> y = -2 gives the point (0, -2)
x = 1 -> y = -5 gives the point (1, -5 )
A is 3
B she can pick 2 by 2
