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:
56 is the other number
Step-by-step explanation:
let the first number be a
the other number is 5/14 from the question
a x 5/14 = 20
5a/14 = 20
5a = 14 x 20 = 280
a = 280/5 = 56
You would factor a 5x out of the numerator sine there is a 5x in 5x^3, 10x^2 and 15x. when you factor, it should be 5x( x^2+2x+3). The 5x on top and bottom would then cancel out, leaving x^2+2x+3 as you answer.
