Step-by-step explanation:
Here is a helpful method I taught my students in my mini lesson...
For you to remember, 22= 4, and 32= 9. Hence the answer to the root of 8 lies between the numbers 2 and 3. However, since the square of 3 equals to 9 which is larger than 8, the root 8 value lies in between the number 2.8 and 2.9.
 
        
             
        
        
        
“Jesse bought 10 more pencils than erasers”       means    P = 10 + E
  “A pencil costs $0.15”   means that     $0.15*P was spent on pencils
  “an eraser costs $.22”    means that    $0.22*E was spent on erasers
  “He paid a total of $4.46”    means that   $0.15*P + $0.22*E = $4.46
 15*(10+E)   +   22*E    =   446
                        150 + 37E = 446
                           37E = 296
                               E = 8   Jesse bought 8 erasers

Answer:
   90° CCW
Step-by-step explanation:
The transformation from B to B' is ...
   B(-4, 1) ⇒ B'(-1, -4)
   (x, y) ⇒ (-y, x) . . . . . matches the transformation for 90° CCW

Answer:
   yes
Step-by-step explanation:
The point is on the line.
The coordinate values satisfy the equation:
   1/3x + y = 12
   1/3(3) + 11 = 12 . . . substitute for x and y
   1 + 11 = 12 . . . . . . . true
Any point that satisfies the equation is a solution. (3, 11) is a solution.
