Answer:
A product of factors is zero if and only if one or more of the factors is zero. That is, if ab = 0, then either a = 0 or b = 0 (or both).
Hence (x+3)(x+12) = 0 only if (x+3) = 0 or (x+12) = 0 or both. (x+3) = 0 when x = 3.(x+12) = 0 when x = 12.
Hence the values of x that make (x+3)(x+12) = 0 are x = 3 and x = 12.
30000= 100%
x=5%
30000/x=100/5
<span>(30000/x)*x=(100/5)*x
</span>30000=20*x
30000/20=x
x=1500
5%of 30000 is 1500
The pairs of f(x) =-3x+5 can be found by putting value of x and getting f(x).
x=0, f(x)=5
X=-1, f(x) =3+5=8
x=1, f(x)= -3+5=2
So few ordered pairs arw (0,5) ,(1,2),(-1,8) etc.
The probability of the student picked will be a junior is 27 percent.
there is a total of 30 kids. 8 are juniors. 8/30 = 0.266
move the decimal back two spaces for a percent. 26.6% is your precise answer. after rlunding it wpuld be 27 percent.
hope this helps
