No 11.473 is greater then 11.447
Table:
x y
-3 0.5
-2 1
-1 2.5
0 5
1 8.5
Now, y = ax^2 + bx + c
Start replacing x = 0 and y = 5
5 = a(0) + b(0) + c => c = 5.
Now, replace any other two pair of data:
(-2, 1) => -1 = a(-2)^2 + b(-2)
-1 = 4a - 2b
(1, 8.5) => 8.5 = a(1)^2 + b(1)
8.5 = a + b
Solve the system
4a - 2b = - 1
a + b = 8.5
=>
4a - 2b = - 1
2a + 2b = 17
-------------------------
6a = 16
=> a = 16 / 6 = 8/3
b = 8.5 - a = 17/2 - 8/3 = 35/6
=> y = (8/3)x^2 + (35/6)x + 5 <--------- answer
Answer:
-6 gal/min
Step-by-step explanation:
(-4 1/2 gal)/(3/4 min) =
= (-4.5 gal)/(0.75)
= -6 gal/min
Answer: -6 gal/min
ANSWER - x= 4
steps : 3 time x which is 3x and 3 times 2 then 9 times 6 which is 54 and 9 times x then add nine to both sides to cancel out the -9x then it’s 12x + 6 = 54 now subtract 6 from both sides and you get 12x = 48 now divide both sides by 12 and you get 4
Answer:
x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.
Step-by-step explanation:
6x+2y=4
2x+4y=18
---------------
-2(6x+2y)=-2(4)
2x+4y=18
-------------------------
-12x-4y=-8
2x+4y=18
----------------
-10x=10
x=10/-10
x=-1
6(-1)+2y=4
-6+2y=4
2y=4-(-6)
2y=4+6
2y=10
y=10/2
y=5
