Select the correct answer from each drop-down menu. Consider the equations below.
A. y=-2x^2-8x
B. y=2(x+6)(x-2)
C. y=x^2-8x+16
D. y=2(x+4)^2-2
Use the equations to complete the following statements.

Equation (A,B,C, or D) reveals its extreme value without needing to be altered. The extreme value of this equation has a (minimum or maximum) at the point (-4,-3,0 or 2 , -32,-8,8, or -2 ).

Answers

Answer 1

Answer:

From each of the given equations, the option which gives a squared expression for the variable with x ; hence does not need any further mathematical calculation in other to determine it's extremes is the expression y = 2(x+4)² - 2 ; option (D) with minimum at the points (-4, - 2)

The extreme vlaue of an expression has a minimum at ;

Obtain the value of x when (x + 4) = 0:

x + 4 = 0

x = - 4

Substitute -4into the equation :

y = 2(-4 + 4)² - 2

2(0) - 2 = - 2

Therefore, the equation has its extremesat (-4,-2)

Step-by-step explanation:

How many solutions are there to the equation below ? 8x+47 =8 (x+5)

Answers

First, distribute the right side.

8*(x + 5) = 8x + 40

Then, we write the whole equation:

8x + 47 = 8x + 40

Looking at it, we can subtract 8x from both sides, so that we're left with:

47 = 40

However, we obviously know that 47 is NOT equal to 40, so there is no solution for this equation.

the ratio of blue marbles to red marbles in a bag is 11:9.If there are 99 blue marbles in the bag,how many red marbles are there?

Answers

Let the number of red marbles be x.

We have: 99/x = 11/9

Cross multiply:
11x = 99*9
⇒ x= (99*9/11)= 81

There are 81 red marbles~

I thought of a number, multiplied it by 2 1/2 , divided the result by 1 1/5 , subtracted 7/18 from it, and got 1 5/6 . What was my number?

The number is 16/15

What is a fraction?

A fraction is the ratio of two integers.

it is usually two integers written above and below and dividing line.

These integers are called numerators and denominators.

Analysis:

Let the number be x

1 1/2 =5/2, 1 5/6 = 11/6 1 1/5 = 6/5

(5/2x / 6/5) - 7/18 = 11/6

(5/2x × 5/6) - 7/18 = 11/6

25x/12 - 7/18 = 11/6

taking LCM of 12 and 18

$(75x-14)/(36)$ = 11/6

6(75x - 14) = 11 x 36

75x - 14 = 6 x 11

75x = 66 + 14

75x = 80

x 80/75 = 16/15

In conclusion, the number is 16/15

Step-by-step explanation:

Determine whether the following statement is always, sometimes, never true. Justify your reasoning.If the scale factor of a scale drawing is greater than one, the scale drawing is larger than the actual object.

Answers

The statement 'If the scale factor of a scale drawing is greater than one, the scale drawing is larger than the actual object.' is always true. If the scale factor of scale drawing is larger than one, the dimensions of the drawing are multiplied by that number. The only way that it would not be larger would either be if the scale factor is not larger than one or if the dimensions of the drawing are negative. However, since the dimensions of a drawing cannot be negative and the scale factor will be greater than one (in this example) the statement is always true.

Answer: always true
