Answer:

[tex]( - inf, - 3.5) \\ ( - 1, 2.5)[/tex]

These are interval for increasing (doesnt include relative max-min)

Step-by-step explanation:

Increasing means when we input the value of x and we get the increase of y-value.

A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.

The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.

Since we only want the increasing. We look at the graph and tell which region does the graph face up and that is the increasing.

Step-by-step explanation:

3a² - 24ab + 48b² = 3 ( a - 4b )²

We will start by rewriting the given quadratic polynomial,

3a² - 24ab + 48b²

Taking out the common "3",

=> 3 ( a² - 8ab + 16b² )

Splitting the middle term i.e. " - 8ab " appropriately,

=> 3 ( a² - 4ab - 4ab + 16b² )

=> 3 [ a ( a - 4b ) - 4b ( a + 4b ) ]

=> 3 ( a - 4b ) ( a - 4b )

Hence, option C is correct.

Answer:

[tex]\huge\boxed{\tt{ 3 (a-4b)(a-4b)}}[/tex]

Step-by-step explanation:

[tex]\sf 3a^2-24ab+48b^2\\\\Taking \ 3 \ as \ common\\\\= 3 (a^2-8ab+16b^2)\\\\= 3 [(a)^2 - 2 (a)(4) + (4b)^2]\\\\Using \ Formula \ a^2 - 2ab + b^2 = (a-b)^2\\\\= 3 (a-4b)^2\\\\= 3 (a-4b)(a-4b)\\\\\rule[225]{225}{2}[/tex]

The axis of symmetry is the x- axis of the vetex.

Step-by-step explanation:

23.1+x=-6.2

x=-6.2-23.1

x= -29.3

Answer:

х= -29.3

Step-by-step explanation:

Subtract 23.1 from both sides then simplify

Answer:

782

Step-by-step explanation:

Since it's asking for the before game miles youd have to take he total yards.

(871)

The you wanna take the total yards ran from that one game.

(89)

Then just subtract by the number of yards total and the number of yards ran in that one game.

871-89=782

Answer:

h=−5/49

Step-by-step explanation:

Answer: D.  T <-9, -2> (ΔABC) = ΔDEF

Step-by-step explanation:

D = A

A (3, 0) --> D (-6, -2)

To get the x-coordinate of D, you add -9 to 3

To get the y-coordinate of D, you add -2 to 0

T <-9, -2> (ΔABC) = ΔDEF

Hope this helped!

Answer:

x +10 =0 (1)

-8x -9y=1 (2)

x=-10 => (2) 80-9y=1 =>y=9

=> x=-10, y=9

Step-by-step explanation:

Answer:

The value of x is 3

Step-by-step explanation:

Here, we want to find the value of x

to do this, we apply the principle of similar triangles

That would work as follows;

4/x + 5 = 7/(2x + x + 5)

4/x + 5 = 7/3x + 5

4(3x + 5) = 7(x + 5)

12x + 20 = 7x + 35

12x - 7x = 35-20

5x = 15

x = 15/5

x = 3

Answer:

225%

Step-by-step explanation:

Find the difference between the two prices, then divide it by the original price:

78 - 24 = 54

54/24

= 2.25

So, the markup rate is 225%

Answer:

20

Step-by-step explanation:

if f(x)=1/5(6-x)^2 when f(16)you will replace x by 16 then solve it like this

f(16)=1/5(6-16)^2

= 1/5(-10)^2

=1/5(100)

=20

Answer:

541.1 square feet

Step-by-step explanation:

A = πr²

1) convert in. to ft because answer is in sq. ft

78 in => 6.5 ft

2) Find radius of entire area

6.5 ft + radius of inner circle

6.5 + 10 = 16.5

3) Calculate area of combined circles

A = π(16.5)²

A = 855.3 sq. ft

4) Find area of inner circle

A = π(10)²

A = 314.2 sq. ft

5) Subtract area of inner circle from combined area

855.3 sq ft - 314.2 sq. ft = 541.1 sq. ft
