Answer:

$k=-2j+24$

Step-by-step explanation:

Take two points from the graph

(0,24) and (6,12)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{k2-k1}{j2-j1}$

substitute

$m=\frac{12-24}{6-0}$

$m=\frac{-12}{6}=-2$ ---> is negative because is a decreasing function

Find the equation of the line in slope intercept form

$k=mj+b$

we have

$m=-2\\b=24$

Note: The y-intercept is given (0,24)

substitute

$k=-2j+24$

How can you determine if a realationship is linear from a table, a graph, or and equation

Ivan

It is linear through a:

Table: the y values have a constant rate of change. For example the y values would be 7, 14, 21, 28 going up by 7 each time. This would not be an example: 6, 12, 17, 18.

Graph: The line of the graph is straight!

Equation: It is in y=mx+b or slope intercept form. Hope this helps!

In a sequence of ten terms, each term (starting with the third term) is equal to the sum of the two previous terms. The seventh

poizon [28]

Answer:

$\boxed{a_1+a_2+a_3+a_4+a_5+a_6+a_7+a_8+a_9+a_{10}=66}$

Step-by-step explanation:

We know that in a sequence of ten terms, each term (starting with the third term) is equal to the sum of the two previous terms. The seventh term is equal to 6. Therefore, we have

$a_1+a_2=x\\a_3=x\\a_4=2x\\a_5=3x\\a_6=5x\\a_7=8x\\$

We know that:

$a_7=6\\\implies 8x=6\\x=\frac{3}{4}$

We get:

$a_1+a_2=x=\frac{3}{4}\\\\a_3=x=\frac{3}{4}\\\\a_4=2x=\frac{3}{2}\\\\a_5=3x=\frac{9}{4}\\\\a_6=5x=\frac{15}{4}\\\\a_7=8x=6\\\\a_8=13x=\frac{39}{4}\\\\a_9=21x=\frac{63}{4}\\\\a_{10}=34x=\frac{102}{4}\\$

Therefore, we calculate

$\boxed{a_1+a_2+a_3+a_4+a_5+a_6+a_7+a_8+a_9+a_{10}=66}$
