Answer:
B, C, D are functions
Step-by-step explanation:
Functions are those that do not share an x value. Look at A. x-values are used twice everywhere except the vertex. This is not a function, it is just a relation. B does not at any time share x-values, so this is a function. C is also a function, and so is D. F is a vertical line that shares the same x value throughout the whole line, so this is definitely not a function.
Answer:
False, A polygon must have at least 3 sides.
Step-by-step explanation:
A polygon must have at least 3 sides. Not at least 2 sides.
We know that
10 hundred is equals to 1 thousand
so
X-----------------> is 20 thousands
x=20*10--------> x=200 hundreds
the answer is
200 hundreds
Let the tens be x.
Therefore the hundreds will be (26 - x).
Since they both total to 26. x + (26 - x) = 26
10*x + 100*(26 - x) = 1610
10x + 2600 - 100x = 1610
10x - 100x = 1610 - 2600
-90x = -990
x = -990/-90
x = 11.
So the 10s are x =11, the 100s are (26 -11) = 15
11 tens bills and 15 hundred bills.
Answer:
Mr Singleton will only need $198 to buy calculator for the 9 student without one. Therefore run fundraiser to raise $1000 for this is No it is much too high
