Choose all of the points that would be on a graph for y=7x
pav-90 [236]
Hey there! :D

Plug in the points to see if they work. 

y=7x

(2,14) -> (x,y)

14=7*2

14=14

That works. 

(0,0) 

0=7*0

0=0

That works 

(1,7)

7=7*1

7=7

That works. 

The points that work are (2,14), (0,0), and (1,7)

I hope this helps!

Find all the integers,b, that make up the trinomial x2 + bx + 10 factorable.
KonstantinChe [14]

By the fundamental theorem of algebra, we can write

x^2+bx+10=(x-r_1)(x-r_2)

Expanding the right hand side, we get

x^2+bx+10=x^2-(r_1+r_2)x+r_1r_2\implies\begin{cases}r_1+r_2=-b\\r_1r_2=10\end{cases}

We want b to be an integer, which means r_1,r_2 must also be integers. This means r_1,r_2 must be factors of 10. There are several possibilities:

r_1=\pm10,r_2=\pm1\implies b=-(10+1)=-11\text{ or }b=-(-10-1)=11

r_1=\pm5,r_2=\pm2\implies b=-(5+2)=-7\text{ or }b=-(-5-2)=7

So there are 4 possible values for b: -11, -7, 7, and 11.
