Answer: Choice A.  (8, 4)

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

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Answer:

Commutative property of addition: Changing the order of addends does not change the sum.

Step-by-step explanation:

For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.

The answer is

[tex]y = - 7[/tex]

Answer:

y = -7

Step-by-step explanation:

Hey :)

y = mx + b

*m is equal to the slope...

y = (0)x + b

Plug in the point you have...

-7 = (0) (5) + b

-7 = 0 + b

-7 = b

y = (0)x - 7

y = -7

Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.

Answer: y = -7

Answer:

344 visitors

Step-by-step explanation:

Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as

y=14.1x+62.0

when the daily rainfall is 20 mm, the number of visitors

y = 14.1(20) + 62

= 282 + 62

= 344

It means that the expected number of visitors is 344 persons (to the nearest integer).

Answer:

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

Step-by-step explanation:

Simplifying expressions...

1. use as many steps as you need, don't take shortcuts or try to do too much in one step... only touch each item in the expression once at most at each step

2. Follow PEMDAS

3. consider some of the rules of exponents: (a/b)^n = (a^n)/(b^n) and (x)^(-n) = 1/(x^n) and a^(b^c) = a^(bc)

examples x^(-4) = 1/(x^4)

                3^(-x) = 1/(3^x)

                (2/x)^(-n) = (1/(2/x))^n = (x/2)^n

                 2^(-x^3) = 2^(-3x) = 1/(2^3x)

so for example

2^(-x) - (x)^(-n) + (-n)^(x^(-2)) touch each part only once, do what you can

1/(2^x) - 1/(x^n) + (-n)^(-2x) the third part needed two steps, so be it

1/(x^n) - 1/(x^n) + (1/((-n)^2x)

Hey!

0.309<0.32<0.35<0.4

hope this helps you

The numbers in order of size start with the smallest can be done as 0.309 < 0.32 < 0.35 < 0.40.

The decimal numeral system is the most widely used system for representing both integer and non-integer values. It is the Hindu-Arabic numeral system's expansion to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system.

The given number can be arranged from smallest to largest can be arranged as shown below. Therefore, we can write,

0.309 < 0.32 < 0.35 < 0.40

Hence, the numbers in order of size start with the smallest can be done as 0.309 < 0.32 < 0.35 < 0.40.

Answer:

Step-by-step explanation:

Answer in your own words:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. Which can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.  

• The scale factor of a dilated figure is denoted by 'r' or 'k'.

• If the scale factor is more than 1 (k > 1), the image is enlarged.

• If the scale factor is less than 1 (0< k <1), the image is contracted.

• If the scale factor is 1 (k = 1), the image remains the same.

• The scale factor cannot be zero.

Scale factor = k

Pre-image lengths: a, b  

(perimeter = 2a + 2b)

Image lengths: ka, kb

(perimeter = 2ka + 2 kb or k (2a + 2b))

Marissa needs to say that the perimeter of the image is the perimeter of the pre-image times the same scale factor.

area of the pre-image = ab

area of the image = (ka)(kb) or k^2 (ab) (The area of the image is the area of the preimage times the square of the scale factor)

Scale factor 5 (then repeat it with scale factor 6)

length of the pre-image = 3 x 4  

(perimeter = 2 (3 + 4) = 2(7) = 14)

length of the image = (3x5) x (4x5) = 15 x 20= 300

(perimeter = 2 (15 + 20) = 2 (35) = 70 or 14 x 5 = 70  

area of the pre-image = 3 x 4 = 12

area of the image = 15 x 20 = 300

12 x (5^2) = 12 x 25 = 300
