A1=6*1-12=-6 arithmetic sequence
a14=6*14-12=72
sum =n(a(1)+a(n))/2
sum =14*(-6+72)/2=462
Answer:
987
Step-by-step explanation:
Answer:
g(x) = -2x - 2
Step-by-step explanation:
g(x) = f(x) - 1
= -2x - 2 {the pattern of function graph moving up and down}
5x^2+60x=0
x(5x+60)=0
x=0
and
5x+60=0
5x=-60
x=-12
therefore, the first option is correct
Answer:
3.76
Step-by-step explanation:
Esther uses 9.4 pints of blur paint and white pant for her bedroom
3/5 of this amount is blue paint while the rest is white paint
3/5
= 0.6×100
= 60
Therefore the amount of white paint can be calculated as follows
40/100 × 9.4
= 0.4×9.4
= 3.76
