Answer:
Domain (-∞,∞). Range= f(x) >-5
Step-by-step explanation:
1) Since we are dealing with a polynomial function with no algebraic restrictions, no denominators, no variables at the exponents, no square roots, etc. And it is a continuous function the Domain is the whole Real Line the Real set of Numbers.
2) As the Range, we have to deal with the combined inverse of this polynomial function.
Do the inversion
Then susbtitute u²= and u=y² back substitute then solve
Jus like this
Back substitute and then solve it for y:
y²=x+
Then y>-5 R=(-5,∞)
Hey there! I'm happy to help!
We see that Steve runs 2.5 miles per day and Sam runs 6.5 miles per day. If you add these together, we see that they run 9 miles every day.
We now need to see how many of these 9 mile days fit into this 450 miles. Let's divide 450 by 9 and we will see how many days it will take for them to reach 450 miles combined.
450÷9=50
Therefore, it will take Steve and Sam 50 days to reach 450 miles combined!
Have a wonderful day! :D
$315, i cant give a thorough explanation since i did it all in my head but basically amal gets 5 portions of the money and Salma gets 9, meaning she gets 4 more, so if 4 portions is $252 then it cant be any of the others since they are too low or way too high, $315 is the only reasonable one.
Answer:
Second choice
Explanation :
The postulate that is used in order to prove the congruency of the triangles is the ASA which means (Angle – Side – Angle). The property that is applicable for the congruency of DB to itself is the reflexive property. Therefore, the answer to this item is the second choice.
Hope I helped! :)
If yes mark me BRAINLIEST!
Tysm!
Answer:
A
Step-by-step explanation: I am not for sure but I would think that cuz if your dealing with lines and point you gonna end up doing slope and slope is Y=MX+B
