Since its telling you that x is the number of years and the question is "How much does the cost of milk increase EVERY YEAR" then you can conclude that the cost is increasing by 0.25 each year
Answer:
A) $14 per hour
B) Luis earns two dollars per hour more than Carl
Step-by-step explanation:
Oooh, looks fun
ok
erm
we might want to know some properties


if

where a=a, then assume m=n

so



minus 17*2^x both sides

use u subsitution, u=2ˣ

solve

or

ac method
2 times 8=16
what 2 number multiply to get -17 and add to get 16
-16 and -1
2u²-1u-16u+8=0
(2u²-1u)+(-16u+8)=0
u(2u-1)+(-8)(2u-1)=0
(u-8)(2u-1)+0
u-8=0
u=8
2u-1=0
2u=1
u=1/2
now
u=2ˣ
8=2ˣ

3=x
and


-1=x
x=-1 and 3
neat problem
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
