Answer:
1.) 10000, -3, 1000 ; doesn't make sense
2.) 40000, 3, 40000 makes sense
3.) 32500, 1.5, 32500 makes sense
4.) [0,+ ∞ ]
Step-by-step explanation:
1.) r(-3) = 2500 - 3*5000=10000
2.) f(3) = 25000 + 3*5000 = 40000
3.) f(1.5) = 25000 +1.5*5000= 325000
4.) # of siblings must >= 0
-4/6 times 2 is -8/12
x - 8/12= x + 2/12
0=10/12
0=5/6
but since 0 does not equal 5/6, this will be no solution
Picture 1: The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads
books per week.
Picture 3: 80% is equal to
.
Step-by-step explanation:
Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.
Given,
Price of turkey sandwich = $9.25
Price of salad = $4.35
Total amount = 9.25+4.35 = $13.60
Tax = 7.5%
Amount of tax = 7.5% of total cost
Amount of tax = 
Amount of tax = 
The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads 1/4 book every 2/3 week. How many books does Christian read per week?
Given,
Books read every 2/3 weeks = 1/4 books

For determining the number of books read per week, we will multiply both sides by 

Christian reads
books per week.
Picture 3: What percent is equivalent to
?
We will multiply the given fraction with hundred for calculating the percentage.

Therefore,
80% is equal to

Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)
another way to do it:
f(x)=x²-10x+16
the vertex is when x=-

, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
