What is the intersection of y=7 and y=1\2x+6
kotegsom [21]
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7

and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so

to find the intersection, yo just find when both sentances are correct so

y=7
subsitute that into y=1/2x+6

7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x

so the point (2,7) is the intersection

a 2 1/2m board is to be used for making shelves,each using up 5/6m of board. Does he have enough board left to make another shel
Hunter-Best [27]
I dont think so because if you multiply 2 1/2 by 5/6 you would get 2 1/12 which means that you can make the first shelf but you would need to subtract 2 1/2 minus 2 1/12 and you would get 5/12. And 5/12 is not the same as 4/5

kirill [66]

Answer:

<em>Felix earns total $594 per week.</em>

Step-by-step explanation:

Felix’s sales are $53000.

So, <u>the amount of sales over $4800 will be</u>:  \$53000-\$4800= \$48200

Felix earns $450 per week and additional 3% of sales over $4800.

So, his additional income = (\$4800\times 0.03)=\$144

Thus, Felix's total income will be:  (\$450+\$144)=\$594
