The answer is b, 5x^2 + 24x + 1
Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
Answer:
6 + 8x
46
Step-by-step explanation:
1. Write the expression
6 + 8x
2. Plug in 5 for x
6 + 8(5) → 6 + 40 = 46
You can find this by doing: 64 points/ 8 games.
Therefore, she scored 8 points a game.
