Answer:

[tex]\frac{mCD-mGE}{2}[/tex]

Step-by-step explanation:

It's the equation to find an exterior angle.

Answer:

-9x^2+911x-202

Step-by-step explanation:

You will need to multiply each term in the parenthesis with each term in the other parenthesis.

Answer:

Original Ratio: 100:200

Divide both sides by 100: 1:2

The ratio 1:2 cannot be simplified further, so 1:2 is he correct answer.

Answer:

Option C

Step-by-step explanation:

The translation rule for the given question is:

[tex](x+3,y-2)[/tex]

Two units down, three units right.

The coordinates of the triangle are (-3, 5) and (-1, 2).

[tex](-5,2) \rightarrow (-5+3,2-2)\rightarrow\boxed{(-2,0)}\\\\\\(-3,5)\rightarrow (-3+3,5-2)\rightarrow\boxed{(0,3)}\\\\\\(-1,2)\rightarrow(-1+3,2-2)\rightarrow\boxed{(2,0)}[/tex]

Option C should be the correct answer.

Hope this helps!

Step-by-step explanation: I dont know this either

Answer:

x = 3

y = 2

Step-by-step explanation:

5x + 4y= 23

x - y = 1   then x = y + 1

substitute for x:

5(y + 1) + 4y = 23

simplify:

9y = 18

y = 2

x = 2 + 1 = 3

check:

3-2 = 1

1 = 1

and:

5(3) + 4(2) = 23

23 = 23

Answer:

y = 3x² + 15x + 12

Step-by-step explanation:

A quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = 3(x + 4)(x + 1) ← expand the factors using FOIL

  = 3(x² + 5x + 4) ← distribute parenthesis by 3

  = 3x² + 15x + 12

Answer:

this could work y=(-22)x+41

Answer: n = 100 and p close to 1/2

Step-by-step explanation:

Answer: 69.2%

Step-by-step explanation:

There are 101 Year 13 students out of a total number of 146 pupils.

To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:

= Year 13 students/ Total students * 100%

= 101 / 146 * 100%

= 0.692 * 100%

= 69.2%

Answer:

Option (4)

Step-by-step explanation:

Given sequence is,

-3 + 6 + 15 + 24 + ........+ 132

Difference in 1st and 2nd term = 6 - (-3)

                                                   = 9

Difference in 2nd and 3rd term = 15 - 6

                                                    = 9

There is a common difference of 9 in each successive term.

Therefore, it's an arithmetic sequence.

Let the nth term of this sequence is (a + bn).

For the first term → n = 0,

a = -3

For second term → n = 1

-3 + b(1) = 6

b = 6 + 3

b = 9

Therefore, nth term of the sequence will be,

[tex]T_n[/tex] = -3 + 9n

For nth term = 132

-3 + 9n = 132

9n = 135

n = [tex]\frac{135}{9}[/tex]

n = 15

Sum of 15 terms can be represented by the expression;

[tex]\sum_{n=0}^{15}(-3+9n)[/tex]

Option (4) is the answer.

Answer:

D) 10.00 for a 36 pack

Step-by-step explanation:

(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)

1.80 for a 6 pack (double it to become a 12 pack)

3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)

5.40 for a 18 pack (add another 6pack)

7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)

9 for a 30 pack

10.80 for a 36 pack

Answer:

8^2-60 ,   11^1   , 2^2x5

Step-by-step explanation:

2^2= 4

4 x 5 = 20

11^1= 11

8^2= 64

64-60 = 4

Answer:

3 : 10

Step-by-step explanation:

Given that :

Total number of rolls = 50

Nunber of times '4' appeared = 15

Expressing the Number of times 4 appeared and the total number of rolls as a ratio:

Number of times 4 appear : total number of rolls

15 : 50

We reduce the the lowest term :

Divide both sides by 5

3 : 10

Answer:

Step-by-step explanation:

1) Area of garden = side * side

                             = 10* 10

                             = 100 Sq.m

2) Area of each flowerbed = 1*1 = 1 sqm

3)  Area of 4 flowerbed = 1 * 4 = 4 sqm

 Area of the remaining garden = Area of garden - area of 4 flower bed

                                                    = 100 - 4

                                                    = 96 sq.m

4) Length of the fence = 4 *side

                                      = 4 * 10 = 40 m

5)  Cost of planting in the remaining garden = 96 * 20

                                                                          = ₹ 1920

Answer:

25

Step-by-step explanation:

hopw this helps

Answer: That would be called absolute value (how far a number is from zero) so that means that it could be any number as long as the negative AND POSITIVE version of the number has lines on each side of it. In this case since you're using 4( which is positive) the answer would be -4( which is negative).  

The functions are not fractions and do not have a denominator so there is no horizontal asymptote.

The answer is 0

Answer: the answer is -10

Step-by-step explanation:

the asymptote is always k

y = f(x+k) or  y = f(x-k)
