Answer:
In its simplest form the domain is all the values that go into a function, and the range is all the values that come out.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Choose any point and put it into one of the choices of equations. Let's just do (4, 2):
A) y = 2x ⇒ 2 =? 2 * 4 ⇒ 2 ≠ 8 --- eliminate
B) y =1/2x ⇒ 2 =? 4 * (1/2) ⇒ 2 = 2 --- correct; keep it
C) y = 1/2 + x ⇒ 2 =? 1/2 + 4 ⇒ 2 ≠ 4.5 --- eliminate
D) y = 2 + x ⇒ 2 =? 2 + 4 ⇒ 2 ≠ 6 --- eliminate
Thus, B is the correct answer.
Hope this helps!
Answer:
12 days
Step-by-step explanation:
Set up an equation with y = mx + b, where m is the rate and b is the y-intercept (starting value)
Let x represent how many days it takes and y represent how many pages he read:
445 = 24x + 157
Solve for x:
288 = 24x
12 = x
So, it will take him 12 days to finish the book

x + y = 0
distance = lax1 + by1 + cl/√(a^2 + b^2)
= l1(6) + 1(10) + 0l/√(1^2 + 1^2)
= l6 + 10 + 0l/√(1 + 1)
= l16l/√2
= 16/√2
= 8 .2/√2
= 8 . √2.√2/√2
= 8√2
