-4=-1b-(1/3)b
-4=-(4/3)b
-4/-(4/3)=b
b=3
-------------------------------
(1/2)3+(5/3)2
3/6+10/6=13/6
-23/3=13/6a
(-23/3)/(13/6)=a
a=-46/13
the slope is -2
have a nice day :D
8, 15, 17
You can do this by using the Pythagorean Theorem and setting the sides equal to
shorter leg = x
longer leg = x + 7
hypotenuse = 2x + 1
Then solve so that one side is equal to zero and use the quadratic formula.
Answer:
C.) X=3 and X=-6/7
Step-by-step explanation:
Use the quadratic formula to solve
Given: y = 2x^2 - 32x + 56
1) y = 2 [ x^2 - 16x] + 56
2) y = 2 [ (x - 8)^2 - 64 ] + 56
3) y = 2 (x - 8)^2 - 128 + 56
4) y = 2 (x - 8)^2 - 72 <----------- answer
Minimum = vertex = (h,k) = (8, - 72)
=> x-ccordinate of the minimum = 8 <-------- answer
