Answer:
f(3) = 41
Step-by-step explanation:
f(3) = 5 + 4.3^2 = 5 + 36 = 41
Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
You have 10 batteries 3/10 are dead there are only 7/10 batteries that are good. So the expected number of good batteries you could get is 7.
Ans: area = 33
Solution: (in the pic below)
You would divide $29 by 7 batteries to get the price per battery.
29/7 = $4.14 per battery ..
! Check Your Work !
4.14 * 7 = $28.98
round 28.98 to the nearest tenth to get $29.00 even. Hope this helps!! :)
