How many points need to be removed from this graph so

1 answer:

4 0

2 points. You answer this with the vertical line test. There are two pairs of points with the same x-axis, so they make two vertical lines. For it to be a function, it must pass the vertical line test, so no two points have the same x-axis. I hope this helps :)

Find four consecutive integers with a sum of 106.

grandymaker [24]

4 consecutive integers...
x, x + 1, x + 2, x + 3

x + x + 1 + x + 2 + x + 3 = 106
4x + 6 = 106
4x = 106 - 6
4x = 100
x = 100/4
x = 25

x + 1 = 25 + 1 = 26
x + 2 = 25 + 2 = 27
x + 3 = 25 + 3 = 28

ur 4 integers are : 25,26,27,28

express each of the following as product of its prime factors, giving your answer in expanded form. a) 24. b) 63. c) 84. d) 150

To answer this question, you can use a factor tree, or the table thing (I forgot what it’s called.)
You divide the number by one of its PRIME factors, until there is only one left. The numbers you divided it by are written as shown.
Hope this helps. :)

The rule that best supports your answer to Question 5 would be:

Sense the two triangles are congruent you would use CPCTC.

The function f(x) = 15(2)^x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipula

weeeeeb [17]

Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
$\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\ \\ 
\dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x$

Written in plain text: f(x)=15/2*2^x
