11(7+4)=__x7 + 11x__

Answer:

A'(-6, 6) and B'( 9, 6), D( -1, 1) and C( 1.5 , 1)

Step-by-step explanation:

Part A: dilation factor of 3 means you will multiply the given coordinates by 3 so

is given A(-2, 2) and B( 3, 2) and this will become A'(-2*3, 2*3) and B'( 3*3, 2*3)

A'(-6, 6) and B'( 9, 6)

Part B: dilation factor of  [tex]\frac{1}{2}[/tex] you multiply thhe coordinates by this number so

A(-2, 2) and B( 3, 2) will become D( -2*(1/2), 2*(1/2)) and C( 3*(1/2), 2*(1/2))

D( -1, 1) and C( 3/2, 1)

Part (1)

n is some positive integer. Let's say for now that n is even. So n = 2k, for some integer k

This means n-1 = 2k-1 is odd since subtracting 1 from an even number leads to an odd number.

Now multiply n with n-1 to get

n(n-1) = 2k(2k-1) = 2m

where m = k(2k-1) is an integer

The result 2m is even showing that n(n-1) is even

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

Let's say that n is odd this time. That means n = 2k+1 for some integer k

And also n-1 = 2k+1-1 = 2k showing n-1 is even

Now multiply n and n-1

n(n-1) = (2k+1)(2k) = 2k(2k+1) = 2m

where m = k(2k+1) is an integer

We've shown that n(n-1) is even here as well.

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

So overall, n(n-1) is even regardless if n is even or if n is odd.

Either n or n-1 will be even. If you multiply an even number with any number, the result will be even.

=======================================================

Part (2)

n is some positive integer

2n is always even since 2 is a factor of 2n

2n+1 is always odd because we're adding 1 to an even number. The sequence of integers goes even,odd,even,odd, etc and it does this forever.

-----------

Another way to see how 2n+1 is odd is to divide 2n+1 over 2 and you'll find that we get (2n+1)/2 = 2n/2+1/2 = n+0.5

The 0.5 at the end is not an integer, so there's no way that (2n+1)/2 is an integer; therefore 2n+1 is odd.

Answer:

The answer is an angle that equals 180 degrees.

Step-by-step explanation

You would need to draw pictures that are just a line with a semi-circle that has an angle of 180 degrees as your examples.

Answer:

62

Step-by-step explanation:

Let the two digit number be XY

X+Y = 8

10X+Y - (10Y+X) = 10Y+X+10

10X+Y-10Y-X=10Y+X+10

8X-19Y=10

8(8-Y)-19Y=10

64-8Y-19Y=10

27Y=54

Y=2

The number is therefore 62.

The required two-digit number with sum of digits as 8 is 62.

Let us say the number is xy

The place value of digits, x and y in the number xy are 10 and 1 respectively.

So the number xy can be written as 10x+y

When the digits are reversed

The new number or reversed number obtained will be yx

So the new number yx can be written as 10y+x

Since the difference between the original number and the reversed number is 10 more than the reversed number.

So, (10x+y) - (10y+x) = 10 + (10y+x)

8x-19y =10.......(1)

Since the sum of digits is 8

So, x+y = 8......(2)

By solving equations (1) and (2) we get

x=6, y=2

So, the required number is xy i.e. 62.

Therefore, The required two-digit number with sum of digits as 8 is 62.

Step-by-step explanation:

XZ ≅ EG and YZ ≅ FG is enough to make triangles to be congruent by HL. Option b is correct.

Two triangles ΔXYZ and ΔEFG, are given with Y and F are right angles.
Condition to be determine that proves triangles to be congruent by HL.

HL implies hypotenuse and leg pair of the right angle triangle.

Here, two right angle triangle ΔXYZ and ΔEFG to be congruent by HL only if their hypotenuse and one leg is equal i.e. XZ ≅ EG and YZ ≅ FG respectively.

Answer:

0.17 cents per ounce, which is the 20 ounce

Step-by-step explanation:

3.40 / 20 = 0.17 cents per ounce

2.10/14 = 0.15 cents per ounce

Answer:

14 Ounces for $2.10

Step-by-step explanation:

To find the answer you need to find the cost per ounce by dividing the cost by the ounces

3.40/20 = 0.17. So $0.17 per ounce

2.10/14 = 0.15. So $0.15 per ounce

Answer:

2(12x + 10y)  

Step-by-step explanation:

The value of three expression that are equivalent to the given expression (24x + 20y) are,

⇒ 2 (12x + 10y)

⇒ 4 (3x + 5y)

⇒ 48/2x + 40/2y

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ 24x + 20y

Now, We can write the expression as,

⇒ 24x + 20y

⇒ 2 (12x + 10y)

⇒ 4 (3x + 5y)

⇒ 48/2x + 40/2y

iv) [tex](-1, 4), (0,4), (2,5), (3,-6), (3, 7)[/tex]

Step-by-step explanation:

From Function Theory, we remember that a relation is not a function when at least one element from domain (x-coordinate) is related to one or more elements from range (y-coordinate). Hence, there are four possibilities of making the relation not a function:

i)  [tex](-1, 4), (0,4), (2,5), (3,-6), (-1, 7)[/tex]

ii) [tex](-1, 4), (0,4), (2,5), (3,-6), (0, 7)[/tex]
