What value of x makes the equation true? –(9 + (–17)) = –9 + x

x=

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

The trigonometric ratios sine and secant are reciprocals of each other

Give me the equations of two lines that have the same slope but are not parallel.
