The simplified equation of 7y + 8 = 9 + 3y + 2y is 2y = 1

<h3>How to simplify an equation?</h3>

The equation can be simplified as follows:

7y + 8 = 9 + 3y + 2y

We have to combine like terms

Hence,

7y + 8  = 9 + 3y + 2y

7y + 8 = 9 + 5y

subtract 5y from both sides

7y - 5y + 8 = 9 + 5y - 5y

2y + 8 = 9

Let's subtract 8 from both sides

2y + 8 - 8 = 9 - 8

2y = 1

Therefore, the simplified equation of 7y + 8 = 9 + 3y + 2y is 2y = 1

The Vertex of a parabola is at (8-1), and it's why intercept is negative 17, which function represents the parabola
suter [353]

Answer:

The function is equal to y=-(1/4)(x-8)^{2}-1

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(8,-1)

substitute

y=a(x-8)^{2}-1

<u><em>Find the value of a</em></u>

Remember that we have the y-intercept

The y-intercept is the point (0,-17)

substitute

x=0,y=-17

-17=a(0-8)^{2}-1

-17=64a-1

64a=-17+1

64a=-16

a=-16/64

a=-1/4

therefore

The function is equal to

y=-(1/4)(x-8)^{2}-1

see the attached figure to better understand the problem
