I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right
to represent all numbers greater than 7.
Finally, state your answer in set notation if possible.
It is read as {x: x > 7}.

Determine the amount of sales she made that month
<u><em>Answer:</em></u>
6.9 oz and 8.1 oz
<u><em>Explanation:</em></u>
<u>The data collected by Lucilla is as follows:</u>
7.1 oz
6.9 oz
7.3 oz
7.6 oz
8.1 oz
7.5 oz
<u>We need to put this data in order, this will give us:</u>
6.9 , 7.1 , 7.3 , 7.5 , 7.6 and 8.1
<u>We can note that:</u>
smallest value is 6.9 oz
largest value is 8.1 oz
all other values fall in this range
<u>Therefore,</u> the weight of an orange based on her calculations is between 6.9 oz and 8.1 oz
Hope this helps :)
According to your text first equation is
y = 3x+2
second equation is
y = Ix-1I + 1
Definition of our absolute value Ix-1I is
1) we take x-1 with condition x-1≥0 => x≥1
2) we take -(x-1) = -x+1 with x<1
Let's form the first system with condition x≥1
y= 3x+2 and y=x-1+1=> y=x
If the left sides of the equations are equal, than the right sides are equal too
3x+2=x => 3x-x=-2 => 2x=-2 => x=-1
This solution we can't accept because it does not meet the condition
x≥1
Lets's form the second system with condition x<1
y=3x+2 and y= -x+1+1 =. y = -x+2
In the same way as previous the right sides are equal =>
3x+2=-x+2 => 3x+x = +2-2 => 4x=0 => x=0
We accept this solution bacause its meet with condition x<1
When we replace this solution in equation y=3x+2 we got
y=3*0+2=2 Only one solution is (x,y) = (0,2)
Good luck !!!!!
