We FOIL, multiply firsts, outers, inners and lasts, and add them all up.
(x-3)(x+2) = x·x + 2x - 3x + (-3)(2) = x² - x - 6
Answer: x² - x - 6
Number 2 is not an equation.
Step-by-step explanation:
y=2.5| ?
x=0.5| 20
It'll be criss-crossed then it'll be:-
2.5×20=50
The probability of getting all heads is 1 / 2^6 = 1/64 as there is only 1 event where this happens in a possible 2^6 = 64 events. It is the same as the probability of getting all tails. The probability of getting at least 1 head is 1 - p(all tails) = 63/64.
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
well then, so since this equation has that slope therefore
so we're really looking for the equation of a line whose slope is 8/5 and runs through (10,10)
