Answer:
PQ is perpendicular to RS
that is to mean:
PQ⊥RS
Step-by-step explanation:
Answer:
x-intercepts: (12, 0)
Step-by-step explanation:
1) it must be fulfilled that the denominator is different from zero, then for this expression
x^2 -9 ⇒ x^2-3^2 = (x-3)(x+3)⇒ (x-3)(x+3) = 0 ⇒ x = 3 o x = -3 , the dominium is all numbers reals except 3 and -3
2 3/4a=9 1/4
2.75a= 9.25
cross off 2.75 and a will remain
divide 9.26 and 2.75
so a=3.36363636
a=<span>3.36363636
but you can round it to a=3.4ish i guess</span>
