The first one is:
x=2
y= -1
The second one has no solution.
35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
Answer:
x = 1
Step-by-step explanation:
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.
