Answer:
y = 3
x = -3/4
Step-by-step explanation:
To get the initial value, we will make:
x = 0
y = 0
Then solve for the corresponding value of either x and y
Okay then, from the expression
y = 4x + 3
When x=0
y = 4 (0) + 3
y = 0 + 3
y = 3
When y=0
y = 4x + 3
0 = 4x + 3
4x = -3
x = -3/4
The initial value of the Linear function =
y = 3
x = -3/4
If there are y players, and each player needs 4 jerseys,
Total amount of practice jerseys needed = 4y
<span>(a) you can show the concentration by:
amount of salt / amount of water
amount of salt
= 30g / L
= [ 30 * 25g ] / [ 25L ] , 25L = 1 min
= [ 30 * 25g ] / min
amount of water
= 5000 + 25t
[ 30 * 25t ] / [ 5000 + 25t ]
= [ 30 * 25t ] / 25*[ 200 + t ]
= 30t / [ 200 + t ] yeah
(b)
lim t->∞ [ 30t / ( 200 + t ) ]
= lim t->∞ [ ( (1 / t) * 30t ) / ( (1 / t) * ( 200 + t ) ) ]
= lim t->∞ [ 30 / ( (200 / t) + 1 ) ]
= 30 / ( (200 / ∞) + 1 )
= 30 / 1
= 30

Answer: You have awnsered a & b, but when you fill out the equation, you get y=30.
Step-by-step explanation:
* y= 4(7) + 2
* y= 28 + 2
* y= 30
