Hello!
The independent variable here is <u>whether or not the group received a calculator.</u> This is the factor that is being changed, and this is what is going to affect the results of the test.
The dependent variable in this case is the seventh graders' <u>speed solving the integer problems.</u> This is because this is the variable being affected by the independent variable - whether they have a calculator.
The controlled variables in this case would be both groups are <u>seventh graders, and they are both solving integer problems.</u> These need to maintain constant as if not, they can affect the dependent variable as well.
Hope this helps!
Answer:
Step-by-step explanation:
9 * -9 * -1 =
-81 * -1 =
81 <===
In multiplying (or dividing), if the signs are the same, the result is positive
if the signs are different, the result is negative
these rules do not apply to addition or subtraction
"r (0,0)" is the one point among the following choices given in the question under <span>which transformation there will there be no invariant points.

Answer:
Assuming the problem is actually 5x^2-3y... the answer is 221
Step-by-step explanation:
5(7 times 7) is 245 and 3(8) is 24, therefore 245-24=221
The x intercepts occur when you set the factors equal to 0. x+1=0 & x-6=0 gives you the x-intercepts. x+1=0 -> x=-1. x-6=0 -> x=6. Therefore, -1 & 6 are your x intercepts
