171 rounds to 200, and 727 rounds to 700. 700+200= 900.
The answer is 900.
Answer:
C = D all real Numbers ; R y>= -2
Step-by-step explanation:
for discover the domain we have to look the x axis and check for what x the graph exist. If we look this graph we can see that there are two solid lines.
the two arrows indicate that the graph continues both to left and to the right
so the domain is all real numbers
for the range we have to check the y axis. If we look at the graph we can see that under -2 there is nothing, while up -2 the graph continues to raise,
so the range is y>= -2
so the final answer is C
The statement that is best supported by the data in the stem and leaf plot is D. The most common number of items sold is 15.

The total number of items sold by each student who participated in a fund-raiser is shown in the stem and leaf plot.
Which statement is best supported by the data in the stem and leaf plot?
The number of students who sold between 10 and 20 items is greater than the number of students who sold more then 40 items.
The number of students who sold more than 30 items is greater than the number of students who sold fewer than 30 items.
The most common number of items sold is 30.
The most common number of items sold is 15.
<span>Equation at the end of step 1 :</span><span> (((x3)•y)-(((3x2•y6)•x)•y))-6y = 0
</span><span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> -3x3y7 + x3y - 6y</span> = <span> -y • (3x3y6 - x3 + 6)</span>
Trying to factor a multi variable polynomial :
<span> 3.2 </span> Factoring <span> 3x3y6 - x3 + 6</span>
Try to factor this multi-variable trinomial using trial and error<span>
</span>Factorization fails
<span>Equation at the end of step 3 :</span><span> -y • (3x3y6 - x3 + 6) = 0
</span><span>Step 4 :</span>Theory - Roots of a product :
<span> 4.1 </span> A product of several terms equals zero.<span>
</span>When a product of two or more terms equals zero, then at least one of the terms must be zero.<span>
</span>We shall now solve each term = 0 separately<span>
</span>In other words, we are going to solve as many equations as there are terms in the product<span>
</span>Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
<span> 4.2 </span> Solve : -y = 0<span>
</span>Multiply both sides of the equation by (-1) : y = 0
It is impossible as 8 is bigger than 7 and you can’t take it away ur welcome
