Let's solve this problem step by step.
28=8b+13b-35
Step 1: Bring 35 to 28.
28=8b+13b-35
+35 +35
63=8b+13b
Step 2: Add 8b and 13b.
63=21b
Step 3: Divide both sides by 21.
63/21=21b/21
So, the answer for this problem is 3=b.

Answer:
The axis of symmetry is 
Step-by-step explanation:
we know that
In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex
In this problem we have a vertical parabola open upward
The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola
so
therefore
The axis of symmetry is
Answer:
x²+2x-3=0
According to Vieta's formula:
x²-(Sum of roots)x+(product of roots)=0
Sum of roots=-3+1=-2
Product of roots=-3×1=-3
The equation is x²-(-2)x+(-3)=0
x²+2x-3=0
9
230-18.84=211.16
211.16-116.22=94.94
94.94-42.13=52.81
52.81-93.17=-40.36
-40.36-50=-90.36
-90.36-13.12-50=-153.48
-153.48
