Answer:

Option B is correct

(9, 3)

Step-by-step explanation:

Given the system of equations:

x-2y = 3          .....[1]

2x-3y = 9       ......[2]

Multiply equation [1] by 2 both sides we have;

2x-4y = 6               .....[3]

Subtract [3] from [2] to eliminate x we get;

2x-3y-2x+4y = 9-6

Combine like terms;

y = 3

or

y = 3

Substitute in [1] we have;

x-2(3) = 3

x -6 =3

Add 6 to both sides we have;

x = 9

Therefore, the solution for the given system of equations is, (9, 3)

Element X decays radioactively with a half life of 7 minutes. If there are 980 grams of Element X, how long, to the nearest tent
xeze [42]

Answer:

32.3m

Step-by-step explanation:

Use equation A = Ao(0.5)^(t/t½)

Now input values: 40 = 980(0.5)^(t/7)

rearrange for t: t = [7ln(2/49)]/ / ln(0.5). Then from here, you can extract 32.3 as your answer

tester [92]

Answer:

the third choice

Step-by-step explanation:

I haven't done those questions in a long time so I would double check. But I think its choice C because 0 has two functions, and I'm pretty sure that a number can only have 1 output, therefore C is not a function..
