Answer:
a) y= 8x+90 b) 154 pounds
Step-by-step explanation:
a) 90 will be the initial value (b) and 8 will be the slope (m)
this gives the linear function :
y = 8x + 90
b) to find his weight after 8 weeks plug in x=8
y= 64+90
y=154
154 pounds

1.609344 * 100 = 160.934 kilometers
Answer:
P = 9
Step-by-step explanation:
To find y :
[2x + 4y = 10] (x1)
[x + 9y = 12] (x2)
--------------------------- -
2x + 4y = 10
2x + 18y = 24
-------------------------- -
4y = 10
18y = 24
-------------------------- -
14 y = 14
y = 1
To find x :
x + 9y = 12
x + 9(1) = 12
x = 12 - 9
x = 3
Put the x and y to find P
P = x + 6y
P = 3 + 6(1)
P = 9
Answer:
24 weeks
Step-by-step explanation:
12 oz: 16 weeks :: 18 oz: x weeks -->
12/16 = 18/x -->
x = 18*16/12 weeks -->
x = 24 weeks
