Answer:
no solutions
Step-by-step explanation:
if y=2x-5
and y=2x+7
2x-5=2x+7
-5 is not equal to 7
Answer: 
Step-by-step explanation:
Height of the building AB= 443 meters
Distance between the building and the agent at the ground BC= 18 meters
Let x be the angle the agent should shoot his laser gun
Since ΔABC is a right triangle, then
Step 1: Find f'(x):
f'(x) = -6x^2 + 6x
Step 2: Evaluate f'(2) to find the slope of the tangent line at x=2:
f'(2) = -6(2)^2 + 6(2) = -24 + 12 = -12
Step 3: Find f(2), so you have a point on y=f(x):
f(2) = -2·(2)^3 + 3·(2)^2 = -16 + 12 = -4
So, you have the point (2,-4) and the slope of -12.
Step 4: Find the equation of your tangent line:
Using point-slope form you'd have: y + 4 = -12 (x - 2)
That is the equation of the tangent line.
If your teacher is picky and wants slope-intercept, solve that for y to get:
y = -12 x + 20
