You could get two different functions out of this:
<u>2x + 2y = 8</u>
1). <u> 'y' as a function of 'x'</u>
Subtract 2x from each side: 2y = -2x + 8
Divide each side by 2 : <em> y = -x + 4</em>
2). <u> 'x' as a function of 'y' :</u>
Subtract 2y from each side: 2x = -2y + 8
Divide each side by 2 : <em> x = -y + 4</em>
Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical. In general, they're
not the same function.
Answer:
5 8
Step-by-step explanation:
Coefficient of x should be 5 so first ? should be 5 let the second ? = z
5×6-9×z=-42
30+42=9z
z=8
Process average or mean
is computed by dividing the total of the measurements made on the process by the number of measurements used to compute the total approximates. For example a coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
A typical length is 100m for the field of play plus the depth of the ingoal areas at both ends of the field, say 10m each - total 120m. The width is typically 70m<span> so the area = 120m x </span>70m<span> = 8400 sq m. A full size pitch (22m ingoal) would be 144m x </span>70m<span> = 10080 sq m.</span>
Answer:
mass on day 1: 3
mass on day 2: 9
mass on day 3: 27
Step-by-step explanation:
using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)
3^1 = 3
3^2 = 9
3^3 = 27
