Answer:the nth term of the sequence, Tn= -3n +12

Step-by-step explanation:

The nth term of an arithmetic progression is given as

Tn=  a+ (n-1) d

where a= first term

and d = common difference

In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that  the number is decreasing by 3

The first term, a= 9

and common difference, d = -3

using our formulae

Tn=  a+ (n-1) d

Tn= 9 + ( n-1) -3

Tn=9- 3n+ 3

Tn= -3n +12

Answer: (x-6)(x+1)

Step-by-step explanation:

Sum :  x2 − 5  x- 6

x2 + x-=6 x − 6

factor pair: x  2 + x − 6 x − 6

x( x+ 1 ) − 6 ( x + 1 )

rewrite from: x (x  + 1 ) − 6 ( x + 1 )

(x-6)(x+1)

Answer:

A: (x-6)(x+1)

Step-by-step explanation:

We need to find 2 numbers that add to make -5 and multiply to make -6.

We already have the numbers infront of us, so by process of elimination we can remove B and D.

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.

If we expand A, it makes the expression that needs to be factorised because...

-6 × 1 = -6

-6 + 1 = -5

So expanding it properly we get.

x² - 6x + x - 6

Simplify.

x² - 5x -6

Answer:

d. V = 668.2 ft³

Step-by-step explanation:

[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]

Answer:

[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]

Step-by-step explanation:

The volume of a triangular prism is found using this formula:

[tex]V=\frac{1}{2} bhl[/tex]

For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.

[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]

Substitute the values into the formula.

[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]

Multiply the first two numbers in parentheses.

[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]

Multiply again.

[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]

Multiply by 1/2 or divide by 2.

[tex]V= 668.22 \ ft^3[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.

[tex]V \approx 668.2 \ ft^3[/tex]

The volume is about 668.2 cubic feet.

4 goes into 17 four times.

4x4= 16

giving you

Answer:

quotient-----4

Remainder---1

Step-by-step explanation:

This is basic division am I right?

Opposite of division is Multiplication

Multiplication is repeated addition

4+4+4+4=16

16+4=20 but that is greater than 17.

so quotient is 4 and remainder is 1

Answer:

ML = 6

Step-by-step explanation:

Since HIJ is a scale drawing of KML, this means the IJ and ML are corresponding sides. The corresponding sides have proportional lengths, so from HJ ≅ LK you can learn that the scale factor is 20 / 5 = 4. likewise you can confirm this with HI ≅ MK is 36 / 9 = 4.

So ML is found by dividing JI by 4 = 24/4 = 6.

Hope that helps!

If x is an odd integer and 2y is an even integer then K. 2y  x is odd.

Odd + Odd = Even.

Odd + Even = Even + Odd = )dd.

Even + Even = Even.

Odd × Odd = Even.

Even × Even = Even.

Odd × Even = Even × Odd = Odd.

Odd ÷ Odd = Even.

Even ÷ Odd = Even Or Odd.

Odd ÷ Even = Fraction/Decimal.

Given, x is an odd integer and 2y is an even integer.

So, y can be even or odd we are not sure.

Therefore, the only option that must be true is 2y + x is odd.

Answer: 11.5 feet

Step-by-step explanation:

We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:

Let the length of Fahims shadow be x

hypotenuse² = opposite² + adjacent ²

13² = 6² + x²

169 = 36 + x²

x² = 169 - 36

x² = 133

x =✓133

x = 11.53

Answer:

x = -5 , y = 10

Step-by-step explanation:

As given ,

a = ( x₁ , y₁ ) = ( -6, 7)

b = ( x₂ , y₂ ) = (-1, -3)

For a -b = ( x₁ - x₂ , y₁ - y₂ )

            = ( -6 - (-1) , 7 - (-3) )

            = ( -6 + 1 , 7 + 3 )

            = ( -5 , 10 )

⇒ a - b = ( -5, 10 ) = ( x, y)

∴ we get

x = -5 , y = 10

Answer:

x = 28

m∠ACD = 68°

Step-by-step explanation:

∠BAE ≅∠DAC because they are vertical angles

∠ACD = 180 - 124 = 56°

to find 'x':   56 + 2x + (180 - 4x) = 180

236 - 2x = 180

-2x = -56

x = 28

m∠ACD = 180 - 4(28)  =  180 - 112  =  68°

Answer:

increase by the percent

The fraction will decrease by 20%.

A fraction represents a part of a whole.

Let's assume the original fraction to be x/y.

If we increase the numerator by 20%, it becomes 1.2x.

If we increase the denominator by 50%, it becomes 1.5y.

So, the new fraction will be:

(1.2x) / (1.5y)

Simplifying this expression, we get:

(4x/5y)

The new fraction is (4/5) times the original fraction.

Therefore, the fraction will decrease by 20%.
