Answer:
A. 2x + 9 + 11 over x - 2
Step-by-step explanation:
2x^2+5x-7 over x-2
divide - 2x^2 + 5x - 7 over x - 2 = 2x + 9x - 7 over x - 2
= 2x + 9x - 7 over x - 2
divide - 9x - 7 over x - 2 = 9 + 11 over x - 2
= 2x + 9 + 11 over x - 2
Answer:
-3 the reaction force will be 3, the net force will have to add up to 0.
Step-by-step explanation:
Answer:

C 8.0
Step-by-step explanation:
Assuming the linear model y=mx+b where m is the slope and b the intercept.
For this case the slope with the following formula:
Where:

After the calculations we see that m=3 and b=2 from the info given by the linear model.
For this case we have the equation obtained by least squares given by:

Where 2 represent the intercept and 3 the slope. We are interested on the best predicted value of y when x=2.
If we see our linear model we have the equation in terms of y and x. So we can replace directly the value of x=2 into the equation and see what we got:
