Answer:
P=32cm
Step-by-step explanation:
Step 1: Cross multiply making it
<u>5 (2t+1)</u> <span>> <u> 9(t) </u></span>
t(2t+1) (t) 2t+1
Step 2: Now that the denominators are the same, we can make simplify it by dividing it by 't (2t+1)'
5(2t+1) > 9(t)
Step 3: Remove parenthesis
10t+5 > 9t
Step 4: Isolate t
10t>9t-5
t > -5 (FINAL ANSWER)
<u>Answer:</u>
D is the correct answer
<u>Explanation:</u>
the following function satisfies each output to its input for the set D
f(x)=x/2
let's check each pair:
0/2=0
-1/2=-0.5
-2/2=-1
-3/2=-1.5
-4/2=-2
the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)
- in A x=-1 | y=2, -2 and this wrong
- in B x=3 | y=9, 16 and this wrong
- in C x=0 | y=0, 1 and this wrong
