Answer:

Step-by-step explanation:

Choose 0 to substitute in for x to find the ordered pair. Remove parentheses. Simplify 3(0)−10 3 ( 0 ) - 10 .

Answer:

x +10 =0 (1)

-8x -9y=1 (2)

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

=> x=-10, y=9

Answer:

38

Step-by-step explanation:

If you’re adding it’s 38

If you’re multiplying its 325

but I think you’re adding so it’s 38

Answer:

356

Step-by-step explanation:

13 x 12= 156

25 x 12= 300

300+156= 356

So the answer is 356

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.

Answer:

=0

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

I am right for sure

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

Answer:

2000

Step-by-step explanation:5%= 100 nickels

1%= 20 nickels

20 x 100 = 2000

Answer:

2,000

Step-by-step explanation:

If 5%=100 nickels , then 20x100=the number of nickels Chi has.  

20x100=2,000

Answer:

on product side there will also 6 carbon atom

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:

x= -8, y= -9

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:

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

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]
