Answer:

The answer to your question is below

Step-by-step explanation:

1.- (2b - 1) (b + 8) = 0

2b - 1 = 0 b + 8 = 0

b = 1/2 b = -8

2.- (x + 3)(x - 12) = 0

x + 3 = 0 x - 12 = 0

x = -3 x = 12

3.- (4b+ 7)(b + 11)

4b + 7 = 0 b + 11 = 0

b = -7/4 b = -11

4.- (k - 8)(k + 6)

k - 8 = 0 k + 6 = 0

k = 8 k = -6

5.- (2n + 12)(5n+ 10)

2n + 12 = 0 5n + 10 = 0

n = -12/2 = -6 n = -10/5 = -2

6.- (w - 3)(3w - 7)

w - 3 = 0 3w - 7 = 0

w = 3 w = 7/3

7.- (6n - 5)(n - 10)

6n - 5 = 0 n - 10 = 0

n = 5/6 n = 10

8.- (n + 12)((4n + 7)

n + 12 = 0 4n + 7 = 0

n = -12 n = -7/4

9.- (3b + 4)(5b - 10)

3b + 4 = 0 5b - 10 = 0

b = -4/3 b = 10/5 = 2

10.- (p - 6)(p + 10)

p - 6 = 0 p + 10 = 0

p = 6 p = -10

The vertex of this parabola is at (3,5) when the y-value is 6 the x value -1 what is the coefficient of the squared term in the

ale4655 [162]

Answer:

1/16

Step-by-step explanation:

Here,

Vertex =(3,5)

x= -1, y=6

Simply,eqn of parabola is given by ax^2+bx+c=y

So, coefficient of squared term (x^2) is 'a'

Therefore, we've to find the value of a

Moving on to solution:

a-b+c=6 ___(i) (by putting the given values of x and y in eqn of parabola )

We know that,

Vetex=(-b/2a, ( 4ac-b^2)/4a)

(3,5) = (-b/2a , (4ac-b^2)/4a)

Equating corresponding sides,we get

3= -b/2a

b=-6a___(ii)

Again,

5=(4ac-b^2)/4a

5=(4ac/4a) - (b^2/4a)

5= c- (36a^2/4a) (by putting value of b from eqn ii )

5= c-9a___(iii)

Now,moving back to the first eqn

a+6a+5+9a=6

16a=1

therefore,a=1/16

Hence ,the required value of coefficient of squared term is 1/16.

I tried my best to give clear explanation as much as I know. It's just we've have to find the value of a . For that, you can use any method you find easier.
