Answer:
a=-3
b=6
Step-by-step explanation:
equation 1: ax+6
equation 2: -3x+b
get the -3 from equation 2 and plug it into equation 1
get the 6 from equation 1 and plug it into equation 2
Answer:
the pic is blocked
Step-by-step explanation:
y = $185.30
x = the orignal cost minus 9% or .09. To increase an objects value by 9% you need to multiply by 1 + .09 or 1.09. So, x being increases by 9% would equal y or $185.30
1.09x = y
1.09x = $185.30
Divide both sides by 1.09
x = $170
Given:
The expression is
To find:
The value of given expression when x=5.
Solution:
We have,
Substituting x=5 in the above expression, we get
On further simplification, we get
Therefore, values of the given expression at x=5 is 87.
