Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3
Answer:
Lenght - Width
2 - 4
3 - 6
5 - 10
7 - 14
Step-by-step explanation:
Because we have 5 and 10, we know that width is lenght multiple by 2, and lenght is width divided by 2.
Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x=

,

. Now we have our first ordered pair:

- for

,

which gives us our next ordered pair:

- for x=2,

, so (2,1)
- for x=4,

, so (4,2)
- for x=8,

, so our last order pair is (8,3)
Finally we can plug the points and joint them to create our graph:
Answer:
x= 0.4
Step-by-step explanation:
x^2 = 4/25 (0.16)
x = 0.4 Square root both sides
