Answer:
x= -15
Step-by-step explanation:
divide 30 by 2 then flip the sign
To find the unit rate do 649.60/116=5.60
($5.60)kg
to find how much for 192 kilograms we have to multiply the unit rate we have to sub in the kg
5.60×192=1075.2
192kg= $1075.20
Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
