Two solutions were found :
x = 9/4 = 2.250
x = 0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
18x - 23x2 = 0
The answer is C
you can buy three shirts because 11×3=33 then you use your coupon and it becomes 33-6= 27
All you need to do is multiply 3 yards by 10 yards to get 30 square yards.
1=5-4 because you have to substitute x and y (x,y) or (5,1)
As stated in (i), the equation of the line is: ln y = -0.015x + .26
(By the way, I checked your answers for parts (i) and (ii) and they are both correct)
(iii)
Plug in (1.1) for y and solve:
ln (1.1) = -0.015x + .26
0.095 = -0.015x + .26
-0.165 = - 0.015x
10.979 = x
Answer: x = 10.979
