The first one : y = ( x-3/2 ) ^2 + 31/4
second one : y = (x+6)^2-25
vertex ; (-6,-25)
33+33+3^0 = 100
(in case you didnt know the third one is three to the power of 0)
If you are solving for b:
-2.6b+4=0.9b-17 <subtract 4 from both sides
-4 -4
-2.6b =0.9b-21 <subtract 0.9b from both sides
-0.9b -0.9b
-3.5b = -21 <divide by -3.5
--------- ------
-3.5 -3.5
b=6
Answer:
- y = -3/5 × -5 - 2
- y = 2 × -1 + 2
Step-by-step explanation:
#1
- y = mx + b
- m = -3/5, x = -5, b = -2, y = y
- put in correct order
#2
- (2, -1) - (5,5) = 6/3 = 2/1 = 2 (remember, y is over x. The formula is y2 - y1 / x2 - x1)
- Pick either point given (2, -1) or (5, 5)
- Plug the point in
- y = y, m = 2, x = 2, b = -1
- Put in order
