Answer:
at first , you need the sum of both equations . It will be like :
2y= 0 + 2
Y=1
_____
now that you know the value of Y , place it in the one of the equation that you like , forexample i place it in the second equation and find out that the value of x is ( -3/2)
1= 2X+5
-4=2X
X= -2
Hope it helps , good luck ^.^

Answer:
B
Step-by-step explanation:
y=x+2. let it eq 1
put y= - 2 and x=-4 in eq 1
-2 = -4+2
-2= -2
now put x= -3 and y= -1 in eq 1
-1 = -3+2
-1 =-1
now put x= -2 and y=0 in eq 1
0 = -2+2
0=0
now put x= -1 and y=1 in eq 1
1 = -1+2
1=1
Answer:
1=256
2=16
3=64
4=4
Step-by-step explanation:
to convert fractions to percentages, we use this formula: x/y = z/100
where x is the fraction numerator, y is the fraction denominator, and z is the percentage
so plug the numbers in: x/12 = 88.2/100
cross multiply: 100x = 1058.4
divide each side by 100: x = 10.584
88.2% = 10.584/12
