The vertex is (2,-1). Thats your answer.
R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
Answer:
<em>The value of b is</em><em> 8</em><em>.</em>
Step-by-step explanation:
The given function is,

The given data is,

i.e when the value of x is -2, then the value of the function is -14.
Putting all the values,




Therefore, the value of b is 8.
