Answer:
Table 1 is not a function because there are two y-values with the same x-values. Remember... y values can repeat but x values cannot repeat when their corresponding y values are different.
Table 2 is a function.
You would need to omit either (3,7) or (3,-2).

The interval that f(x) is increasing is the distance from 200 to 300.
The minimum value of f(x) in the interval 0<x<300 is 200.
At a value of 500, the value of f(x) is 0.
The function can't be a quadratic function since there are two points in the graph where f(x) changes its rate from increasing to decreasing or the opposite. A quadratic function has only one of that point.
Answer:
15 = x
Step-by-step explanation:
3/5x + 22 = 28
-22. -22
3/5x = 6
(5/3)(3/5)x = 6 × (5/3) multiply by the reciprocal
x = 6 × (5/3) -------------> 6 and 3 can be simplify so it will be x = 2 × 5 = 10
check
3/5 (10) + 22 ---> 3 × 2 + 22
28 = 28 ✔
Ok so this is the first page
1.
78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas.
It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one
2.
Online store=$208 and the superstore=$224
The difference is $16 so it would be cheaper to get it at the online store
3.
It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000
Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000
