Let's take a look at the exponent rule:
Her mistake was she multiplied the exponents instead of adding it up.
Answer:
1/6y+1/6(y+12)-2... so the third one
Step-by-step explanation:
1/6y+1/6(y+12)-2
1/6y+1/6y+2-2
2/6y
Reduces to 1/3y
Answer:
Domain: (-5,-4,-3,-2,-1,0,1,2,3,4,5)
Range: (0,1,2,3,4, -1, -2)
Step-by-step explanation:
Domain means all of the x-axis values on the graph, so for example in (-2,0), -2 would be part of the domain and 0 part of the range. Therefor, what you would do would be take all of the plots and put all x values as the domain and all y values as the range. Hope this helped!
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
