Answer:

No solution

Step-by-step explanation:

x + 2y = 9

x = - 2y + 9

2x + 4y = 20

2(-2y + 9) + 4y = 20

-4y + 18 + 4y = 20

-4y + 4y = 20 - 18

Answer:

(12, 12), (18, 21), (24, 0)

Step-by-step explanation:

To dilate a figure, you multiple each of the numbers in its coordinates by the scale factor.

The vertices of the new triangle is:

4. (12,12) (18,21) (24,0)

We have:

The vertices of a triangle: (4, 4) (6,7) and (8,0)

We dilate the triangle by a scale factor of 3

To find the vertices of the new triangle after a dilation of 3, multiply the old vertices by 3. That is:

3 * (4, 4) => (12, 12)

3 * (6, 7) => (18, 21)

3 * (8,0) => (24, 0)

Therefore, the vertices of the new triangle is (12,12) (18,21) (24,0)

Advantages of cluster sampling

Note: Cluster sampling is not as accurate as simple or stratified random sampling.

Answer:

Probability of at least two cuckoo eggs is 0.738.

Step-by-step explanation:

probability of cuckoo egg = 0.1

probability of not a cuckoo egg = 1 - 0.1 = 0.9

Probability of at least two cuckoo eggs is

= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +

probability of three cuckoo eggs

= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9

= 0.009 + 0.729

= 0.738  

Ans5 and 2

Step-by-step explanation:

Answer:

the answe is 187 cm square

Answer:

v = 9 because it is what would make a great answer

Step-by-step explanation:

the angles are supplementary, meaning it sums up to 180 degrees

so to find v, you have to find the total angle of v.

180- 105 equals 8v+3, or 75 equals 8v+3

subtract 75 with 3 leaving 72 equals 8v

v would equal 9

1 year = 12 months.

30 years x 12 months per year = 360 total months

Multiply total months by monthly payment:

360 months x 1,073.21 per month = $386,355.60 total monthly payments for 30 years.

Now add the down payment to the total monthly amount:

$386,355.60 + $45,000 = $431,355.60

Most of the data is clustered in the 80s. Therefore, D is correct.

Answer:

64°

Step-by-step explanation:

We know that a right angle is 90°

so we do 90° - 26° = 64°

The number of children that would usually be around at the Nursery on Monday are; 24 Children

We are given;

Percentage of children that were absent = 34%

Number of children that attend on Monday = 29

Thus;

Number of children that are absent on Monday = 34% * 29

Number of children that are absent on Monday ≈ 10

Thus;

Number of children that would be around on Monday = 34 - 10 = 24 children

Answer:

998796

Step-by-step explanation:

For a number to be divisible by 12. it must be divisible by 3 and  4

Since we need the largest 6 digit number, we will take x = 9

So the number is 9987yz

Again since we need the largest number we will consider the largest 2 digit number multiple of 4 and 3.

Largest 2 digit number divisible by 4 is 96, which is also divisible by 3.

So, yz  = 96

Therefore , the largest number in the form will be : 998796

Answer:

The largest number is 998796

------------------------------------------------------

The largest digit you could use is 9 so, our number would be, 998799,

but the thing is that it's not divisible by 12.

The next largest would be 8. (998798) Not divisible.

7, so our number would be, 998797. Not divisible.

6, 998796. 998796/12= 83233, which means that it is divisble, so, the largest number in the form x987yz that is divisble by 12 is 998796

OPTION B and E are the correct answers.

Answer:

B & E

Step-by-step explanation:

Main Expression: - 8 - ( - 1 ) - 5 = - 7 - 5 = - 12  

A: - 8 - 1 - 5 = - 9 - 5 = - 14  

B: - 8 + 1 - 5 = - 7 - 5 = - 12

C: - 8 + ( - 1 ) + ( - 5 ) = - 9 + ( - 5 ) = - 14

D: ( 8 + 1 ) - 5 = 9 + 5 = 14

E: - ( 8 - 1 + 5 ) = - ( 7 + 5 ) = - ( 12 ) = - 12

2) y=-3x+36

Step-by-step explanation:

Hi there!

We're given a graph and we want to find the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We'll need two points, so pick any two from the graph

For example, let's do (0,36) and (12,0)

first let's find the slope

The formula for the slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points

we'll be using (0,36) and (12,0)

let's label the points to avoid any confusion

x1=0

y1=36

x2=12

y2=0

Now substitute into the formula:

m=(y2-y1)/(x2-x1)

m=(0-36)/(12-0)

m=-36/12

m=-3

so the slope is -3

here's the equation so far:

y=-3x+b

we need to find b

The equation of the line will pass through both (0,36) and (12,0) so we can use either one of them to solve for b

let's take (12,0) for example

substitute 12 as x and 0 as y

0=-3(12)+b

multiply

0=-36+b

add 36 to both sides to isolate b

36=b

now substitute 36 as b into the equation

y=-3x+36

There's the equation of the line, so the answer is option 2

Answer:

first hust rotate 180 and next reflect it over x axis.

the given point (-7,3) id in second quadrant but after rotation it will be in fourth quadrant.

afterwards you have to refect that point over x-axis which gives you the image of the points on first quadrant ie. (7,1).
