Answer:
x > -6
Step-by-step explanation:
Move 6 to the other side:
0.5x > -3
x > -6
First let us calculate the total cost before tax:
1.06 * cost = 16.43
cost = 15.5
Therefore the cost of sunscreen is:
2 * Sunscreen + 6.50 = 15.5
2 * Sunscreen = 9
Sunscreen = $4.50
<span>Hence each bottle of sunscreen cost $4.50</span>
Answer:
you were thinking of 41
Step-by-step explanation:
(x-9)*4=128
(x-9)=128/4
(x-9)=32
x=32+9
x=41
Answer:
(0,3)
Step-by-step explanation:
Given inequality is
y< x+ 4
to check the solution we plug in each ordered pair and check with our inequality
Lets check (-1,4)
here x=-1 and y =4
We plug in -1 for x and 4 for y in our inequality y<x+4
4 < -1 + 4
4 < 3 that is false, so (-1,4) is not our solution
Now we plug in (0,5), x=0 and y = 5
y < x+4
5 < 0 + 4
5<4 that is false, so (0,5) is not our solution
Now we plug in (0,3), x=0 and y = 3
y < x+4
3 < 0 + 4
3<4 that is true, so (0,3) is our solution
The rate of change in x is 5 intervals
and rate of change in f(x) is 3
