oksian1 [2.3K]

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.

A parabola has zeros at (5,0) and (-3,0) and passes through point (6,18) determine the axis of symmetry
worty [1.4K]

Answer:

The axis of symmetry is x=1

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

x=\frac{5-3}{2}=1

therefore

The axis of symmetry is x=1
