Step-by-step explanation:
Given the function that models the income of a family as g(X) = ax+b
at x = 0, g(x) = 42000, the function becomes;
g(X) = ax+b
42000 = a(0)+b
42000 = 0+b
b = 42000
at x = 1, g(x) = 56256
56256 = a(1) + b
56256 = a+b
a = 56256 -b
a = 56256 - 42000
a = 14,256
To get the average family income in 1997, wee need to calculate g(x) at when x = 5, since the number of years between 1992 and 1997 is 5years.
g(x) = ax+b
g(5) = 14256(5) + 42000
g(5) = 71,280+42000
g(5) = 113,280
Hence the average family income in 1997 is 113,280
If we expand -7x ( 5 - x ) ..
.....we have to multiply the outside term with the inside values
there fore if we multiply 7 and 5 the answer is 35....... and the negative symbol will make it negative so it will be -35 and the x in the outside value will be multiplied to it so it will become -35x.....
then if we multiply -7x and -x ...... - sign and the other - sign when multiplied will make + sign
and when x and x are multiplied from both sides it comes as x^2 ( this means x squared )........when 7 is multiplied the final answer will be 7x^2.......
so we will have -35x + 7x^2
SO when this will be arranged in descending order it means from biggest to smallest....so this will be 7x^2 - 35 x

Answer:
20%
Step-by-step explanation:
1.) 125-100/125 --> 25/125 --> .2 --> 20%
She needs to run around it 5 times because if 1 mile is six runs that means 1 mile is 1/6 of a run. 1/6 x 5 =5/6
