Answer:
547 & 544
Step-by-step explanation:
when you round 552 to the nearest 10 its 550 and 544 would be 540.
when rounded to the nearest hundred 552 would be 600 & 544 would be 500.
(could be wrong)
9% of $2500 = 225
7 × 225 + 2500 = $4075
Answer:
Both of those are functions.
Step-by-step explanation:
is a parabola that opens up.
Any upward or downward parabola is a function because they pass the vertical line test.
![x=\pm \sqrt{1-y}{/tex]Square both sides:[tex]x^2=1-y](https://tex.z-dn.net/?f=x%3D%5Cpm%20%5Csqrt%7B1-y%7D%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3ESquare%20both%20sides%3A%3C%2Fp%3E%3Cp%3E%5Btex%5Dx%5E2%3D1-y)
Subtract 1 on both sides:

Multiply both sides by -1:

So this is a another parabola and it is faced down. So this is also a function.
wit
willl always be a parabola.
If
then it is open up.
If
then it is open down.
Upwards and downward parabolas will always be functions.
are also parabolas but these open to the left or right. These will not be functions because they will not pass the vertical line test.
