F(12)=-34(12)+2
f(12)=-408+2
f(12)=-406
The answer is 3/2
3 units up and 2 units to the left that is the slope

Answer:
x=i or no solution exists depending on the user's grade
Step-by-step explanation:
f(x) = 2x^2-5
-7 = 2x^2-5
-2 = 2x^2, x^2=-1, x=i
Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
