Mathematics

Answer:

D is correct.

Step-by-step explanation:

- 2x =  {x}^{2}   - 8

{x}^{2}   + 2x - 8 = 0

(x - 2)(x + 4) = 0

x - 2 = 0 or x + 4 = 0

x = 2 or x = -4

So we have (2, -4) and (-4, 8). D is correct.

AURORKA [14]

The following are the answers to the questions presented:

Part 1:

Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>

Axis of symmetry = x = -3/2

Domain = all real numbers

Range = <span>y </span><span>≤ </span>11/2

Part 2:

A quadratic equation is symmetrical around its vertex. The equation for the axis of symmetry is x = -3/2 since the equation is in terms of x. Since no value of x is undefined, then the domain of the equation is clearly all real numbers. Since the value of “a” is negative, then that means the y coordinate of the vertex is the maximum value so the range will never get above 11/2. I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

A grocery store sells twelve bottles of water for $13.80 a convenient store sells ten bottle of water for $11.80. which store ha
Mrac [35]

At the same rate, the price of 12 bottles of water at the convenience store would be

(12/10)·$11.80 = $14.16 . . . . . this is more than $13.80

On average the cost for the same number of bottles of water is higher at the convenience store. The grocery store has the better buy.

If f(x)=-5^x-4 and g(x)=-3x-2,find (f+g) (x)
ASHA 777 [7]

Answer: (f-g)(x) = - 5^x + 3x - 2

Step-by-step explanation:

if f(x) = -5^x - 4 and g(x)= - 3x - 2,find (f-g)(x)

(f-g)(x) = -5^x - 4 - (-3x - 2)

(f-g)(x) = -5^x - 4 + 3x + 2

(f-g)(x) = - 5^x + 3x - 2
