Answers:
- C) x = plus/minus 11
- B) No real solutions
- C) Two solutions
- A) One solution
- The value <u> 18 </u> goes in the first blank. The value <u> 17 </u> goes in the second blank.
========================================================
Explanations:
- Note how (11)^2 = (11)*(11) = 121 and also (-11)^2 = (-11)*(-11) = 121. The two negatives multiply to a positive. So that's why the solution is x = plus/minus 11. The plus minus breaks down into the two equations x = 11 or x = -11.
- There are no real solutions here because the left hand side can never be negative, no matter what real number you pick for x. As mentioned in problem 1, squaring -11 leads to a positive number 121. The same idea applies here as well.
- The two solutions are x = 0 and x = -2. We set each factor equal to zero through the zero product property. Then we solve each equation for x. The x+2 = 0 leads to x = -2.
- We use the zero product property here as well. We have a repeated factor, so we're only solving one equation and that is x-3 = 0 which leads to x = 3. The only root is x = 3.
- Apply the FOIL rule on (x+1)(x+17) to end up with x^2+17x+1x+17 which simplifies fully to x^2+18x+17. The middle x coefficient is 18, while the constant term is 17.
Answer:
70
Step-by-step explanation:
C and 110° are opposite angles of a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Answer:
For number 1 the answer should be independent.
For number 2 the answer should be independent
And number 3 should also be independent
Step-by-step explanation:
My explanation is that they are all independent because you aren't depending on someone to help you do these things, therefore, independent.
I hope this helps :)
Answer:
Step-by-step explanation:
The card you draw is just as likely to be the ace of spades as that can be selected from any other from 51 cards.So the chance of it being the ace of spades is 1/52
It would be y=Mx+b that is the answer
