Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is 
Step-by-step explanation:
We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.
If -1, 1 and 3 are real zeros, it can be written as:
x= -1, x= 1, and x = 3
or x+1=0, x-1=0 and x-3=0
Finding polynomial by multiply these factors:

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is

Step-by-step explanation:
x- red candy
y- blue candy
x + y = 11
1.29x + .79y = 11.19
129x +79y = 1119
-129x -129y = -1419
-50y = -300
y = 6 lbs. blue
x + 6 = 11
x = 5 lbs. red
