Answer:
A
Step-by-step explanation:
we can conclude from the second equation that when
2x + y = 6 then y = 6 - 2x. so instead of y in the first equation we use 6 - 2x.
now the equation would look like this : 6 - 2x = x^2 - 4x + 3 .
then we bring everything to one side of the equation : x^2 - 2x - 3 .
now we'll have two results for x ( because x^2 - 2x - 3 = 0 has 2 answers )
one of them is -1 and other one is 3.
if we put them in the first equation we will have 8 and 0 for y.
so A is the answer
Answer: 14
Step-by-step explanation:
56 = 100%
56/4 = 14
14 = 25%
25% = 1/4
I know this wont help but y=mx+c or +b will need to be used so y will equal to 3x+5 so the equasion is y=3x+5
sorry, thats all i can do
The first one is 52/161. The second one is correct.
