1) 2a = 9b ⇒ 2:9
2) a + b = 3b ⇒ a = 2b ⇒ 1:2
Answers: 2:9 and 1:2
Answer: f(2) is 3.
Step-by-step explanation:
f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

[One could also determine the equation for the line. Provided below.]
The slope is -(1/2) and the y-intercept is 4:
y = -(1/2)x + 4
For x=2,
y = -(1/2)*(2) + 4
y = 3
y(2) = 3
Translate to fraction
are 30/12 and 40/16 equivilent?
if a/b=c/d then a/b times d/c=1
basically if ad=bc then they are equivilent
30/12 ad 40/16 equvilient?
30/12 times 16/40=1?
480/480=1?
1=1?
yes
they are equivilent
I think your answer would be d. The number one rule of absolute value is no negatives, and the opposite of -179 is 179.
