Answer:
x=4.5 and y= -6
Step-by-step explanation:
2x+5y= -21
-2x+3y= -27
add the two equations: 8y= -48
y=-48/8= -6
sub for y in 2x+5y= -21
2x + 5(-6)=-21, 2x-30= -21
2x= -21+30= 9
x= 9/2=4.5
Answer:
0.1-0.2 is a change of 100% as it is doubled.
Answer:
A
Step-by-step explanation:
The correct divisor is 2. You change the sign of the real number without a variable when that real number is the divisor.
So - 2 becomes 2 and C and D are both incorrect.
The 0 comes between - 2 and 4 because the x term is 0x. (there isn't one).
That makes B wrong.
The answer is A
