For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3
1_1/3 = 4/3
-3_1/4 = -13/4
(4/3) - (-13/4)
(4/3) + (13/4)
We can see that (4/3) + (13/4) leads to a positive answer.
Answer: choice D
Answer:
It would be 20
Step-by-step explanation:
As we can see, the sequence starts from 5 and increases by three each time. In fact, one possible formula for that sequence could be:

Let's confirm the formula by evaluating the first 6 terms:

Answer: Choice A</h3>
Explanation:
Each table has x = 10 in it. Plug this value into the given equation.
y = -2x+17
y = -2*10+17
y = -20+17
y = -3
The input x = 10 leads to the output y = -3. Table A shows this in the middle-most row. So that's why choice A is the answer. The other tables have x = 10 lead to y values that aren't -3 (eg: choice D has x = 10 lead to y = 12), so we can rule them out.
