Let P(x) be the statement"x= x2", If the domain consists of the integers, what are these truth values? (a) P(0) (b) P(1) (c) P(2
jeka57 [31]

Answer: i guess the problem is with P(x) => "x = x^{2}", then P(x) is true if that equality is true, and is false if the equality is false.

so lets see case for case.

a) x = 0, and 0^{2} = 0. So p(0) is true.

b) x = 1 and 1^{2} = 1, so P(1) is true.

c) x = 2, and 2^{2} = 4, and 2 ≠ 4, then P(2) is false.

d) x= -1 and 1^{2} = 1, and 1 ≠ -1, so P(-1) is false.

Question 2
S_A_V [24]

Answer: B -8/7x+11/7

Step-by-step explanation:

First find the slope using teh formule y_{2}-y_1\\x_2-x_1 which is teh formula for slope in this case the slope would be (-8/7) then pick a pair of points in this case we will use (4,-3) plug in the slope and the coordinate pair into the intercept formula (y=mx+b) so it would look like -3=-8/7(4)+b then solve for b so the answer be 8/7x+11/7

ZanzabumX [31]
Ok lets go ahead and see if the following answers can help:
<span>A) if p = 0.2 then C(p) = 157.52
B) if p = 0.95 then C(p) = 753.86
C) smallest p value that gives C(p) > or = 0. This is p = 0
D) largest INTEGER value for C(p) to exist or be >=0. This is p = 99. p = 100 gives 786000/0; does not exist. p > 101 starts giving negative numbers.
</span>I hope this has been of help
