Answer:
$1200
Step-by-step explanation:
3/4 of 1600 is 1200
Answer:
It means that you need to state whether there are any solutions and how many there are. For example if the equation ends up with an answer like 2=5 there is no solution because 2 does not equal 5. if the equation ends up with an answer of 0=0 there is infinitely many solutions because 0 does equal 0. if it comes out as x=9 there is one solution because x only has one answer to (keep in mind these are just examples)
Step-by-step explanation:
The order pair would be where the two lines intersect perpendicularly with each other forming a 90° angle
Answer:
8
Step-by-step explanation:

Answer: t^2=-f-576/16
Step-by-step explanation:
Step 1. Switch the equation around:
-16t^2+576=f
Step 2. Subtract 576 from each side:
-16t^2+576-576=f-576
Step 3. Now simplify:
-16t^2=f-576
Step 4. Divide everything now by -16:
-16t^2/-16=f/-16-576/-16
Step 5. Simplify again:
t^2=-f-576/16
