2z+16=124
124-16=108
108/2=54
19.
To find this you first have to find the f(x) values for x = 5 and x = 8
x = 5
f(x) = 5^2 + 6(5) + 11
f(x) = 25 + 30 + 11
f(x) = 66
x = 8
f(x) = 8^2 + 6(8) + 11
f(x) = 64 + 48 + 11
f(x) = 123
Then you subtract the two from each other to see how much it has changed in those 3 numbers.
123 - 66 = 57.
Then you take that answer and divide it by the change in x (which is 3)
57/3 = 19
Answer:
Step-by-step explanation:
(x²-6x)+(y²+8y)=-21
(x²-6x+9)+(y²+8y+16)=-21+9+16
(x-3)²+(y+4)²=4
center=(3,-4),radius=√4=2
Answer:
D. 24 Units
Step-by-step explanation:
tracing the points given we get a rectangle
the perimeter of a rectangle = 2a+2b
a=length
b= width
in this case a= 8
b= 4
the perimeter of a rectangle = (2*8)+(2*4)
the perimeter of a rectangle = 16+8
the perimeter of a rectangle = 24
Answer:
No, this spigot doesn't fill at a faster rate.
Step-by-step explanation:
The first spigot can fill a pool with 9 gallons of water in a minute. Whereas the second spigot can only fill a pool with 8 gallons of water in a minute. Therefore, the second spigot fills at a faster rate.
