Solve your system of equations.
2x+y=1;4x+2y=−1
Solve 2x+y=1 for y:
2x+y+−2x=1+−2x(Add -2x to both sides)
y=−2x+1
Substitute (−2x+1) for y in 4x+2y=−1:
4x+2y=−1
4x+2(−2x+1)=−1
2=−1(Simplify both sides of the equation)
2+−2=−1+−2(Add -2 to both sides)
0=−3
Answer: No solution. C)
Answer:
Length of AB = Length of C′D′
Length of CD = Length of B′C′
Step-by-step explanation:
Not sure but I think
I think C would equal 15, because 14 + 14 = 28; 15 + 15 = 30 which is greater than 28.
