Answer:

[tex]C" = (-4,-3)[/tex]

Step-by-step explanation:

Given

[tex]C = (4,3)[/tex]

Required

The coordinates of C"

From the question, we understand that:

C is reflected over x-axis to give C'

The rule to this is:

[tex]C(x,y) \to C'(x,-y)[/tex]

So, we have:

[tex]C(4,3) \to C'(4,-3)[/tex]

Next, C' is reflected over y-axis to give C''

The rule to this is:

[tex]C'(x,y) \to C"(-x,y)[/tex]

So, we have:

[tex]C'(4,-3) \to C"(-4,-3)[/tex]

Answer:

A.[tex]2(3^{\frac{1}{3}})-\sqrt[3]{18}[/tex]

Step-by-step explanation:

We are given that

[tex]\frac{6-3(\sqrt[3]{6}}{\sqrt[3]{9}})[/tex]

We have to find the quotient.

[tex]\frac{6}{\sqrt[3]{9}}-3(\frac{\sqrt[3]{6}}{\sqrt[3]{9}})[/tex]

[tex]\frac{2\times 3}{\sqrt[3]{3^2}}-3(\frac{\sqrt[3]{3\times 2}}{\sqrt[3]{3^2}})[/tex]

[tex]2\times\frac{3}{3^{\frac{2}{3}}}-3(\frac{2^{\frac{1}{3}}\times 3^{\frac{1}{3}}}{3^{\frac{2}{3}}})[/tex]

Using the property

[tex](ab)^n=a^n\cdot b^n[/tex]

[tex]2\times 3^{1-\frac{2}{3}}-3(2^{\frac{1}{3}}\times 3^{\frac{1}{3}-\frac{2}{3}})[/tex]

Using the property

[tex]\frac{a^x}{a^y}=a^{x-y}[/tex]

[tex]2(3^{\frac{1}{3}})-3(2^{\frac{1}{3}}\times 3^{-\frac{1}{3}})[/tex]

[tex]2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times 3^{1-\frac{1}{3}}[/tex]

[tex]2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times 3^{\frac{2}{3}}[/tex]

[tex]2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times \sqrt[3]{3^2}[/tex]

[tex]2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times \sqrt[3]{9}[/tex]

[tex]2(3^{\frac{1}{3}})-\sqrt[3]{2\times 9}[/tex]

[tex]2(3^{\frac{1}{3}})-\sqrt[3]{18}[/tex]

Hence, the quotient of [tex]\frac{6-3(\sqrt[3]{6}}{\sqrt[3]{9}})[/tex] is given by

[tex]2(3^{\frac{1}{3}})-\sqrt[3]{18}[/tex]

Cuatro es la respuesta también conocida como d

Answer:

Step-by-step explanation:

Answer:

Maggie did not apply the law correctly

Step-by-step explanation:

Given 3 numbers A, B and C, for a commutative property

(A+B)+C = C+(A+B)

This shows that the remains the same no matter what values comes first

For the given expression

4/5+6.9y-8 = 6.9y+8-4.5

The values are not commutative because of the presence of negative sign. For the expression to be commutative, they must be equal no matter the way it is arranged and the sign must be positive all through for both sides. Hence Maggie did not apply the law correctly

Answer:

1/3 + 6/35

Step-by-step explanation:

We are given;

−2/7 × 1/5 + 1/3 - 4/5 × -2/7

Using the rule of bodmas, we will group them and solve with multiplication being the first operation.

1/3 - (4/5 × -2/7) + (−2/7 × 1/5)

Factorization of first and second bracket gives;

1/3 + 2/7(4/5) + 2/7(-1/5)

Factorizing again gives;

1/3 + 2/7(4/5 - 1/5)

>> 1/3 + 2/7(3/5)

>> 1/3 + 6/35

Answer:

70

Step-by-step explanation:

We have 7 blue marbles, and 20 total marbles. As a result, if we randomly chose one marble from the bag, the probability would be (number of favorable outcomes)/(number of total outcomes) = 7/20.

This means that for each 20 trials, we would expect to pull out a blue marble 7 times, as the probability does not change over time (because we put the marbles back, there are the same amount of each marble). Over 200 trials, we can simply make it out of 200 instead of 20. We can thus multiply 7/20 by 10/10 (10/10 is equal to 1, keeping the proportions equal) to get 70/200, so we can expect 70 blue marbles out of 200.

Answer:

Answer:

ok so if they are congreant that mean the

x=38

Answer:

38

Step-by-step explanation:

Because both x and the 38° can create a linear pair with the same angle, they must be equal. Linear pairs are equal to 180°

Name the bottom angle C.

X + C = 180   (linear pair)

38 + C = 180 (linear pair)

X + C = 38 + C Subtract C from both sides

X = 38

Answer:

the second option

y = (-1/2)x + 11

Step-by-step explanation:

x = 2

y = (-1/2)×2 + 11 = -1 + 11 = 10

the same as the table.

x = 4

y = (-1/2)×4 + 11 = -2 + 11 = 9

the same as the table.

x = 6

y = -3 + 11 = 8

the same as the table.

x = 8

y = -4 + 11 = 7

the same as the table.

Answer:

The data points in Set 1 are more spread out than the points in Set 2 because the mean absolute deviation of set 1 is larger.

Step-by-step explanation:

Given

Mean absolute deviations of set 1 and 2

Required

Complete the gap

From the complete question, we have that:

set 1 has a larger mean absolute deviation than set 2

This means that:

The dataset of set 1 is more spread out than that of set 2

The reason for this is that:

set 1 has a larger mean absolute deviation

Answer:

If f(x) is parallel to the line y=3/4x+b ,it would have to have the same slope.  

In this equation:

y=mx+b

m= is the slope of the line.

A line parallel to the line y=3/4x +2/5 must have the same slope; that it is to say, the slope would be m=3/4

Examples:

y=3/4 x+ 50000

y=3/4 x -51/36

y=3/4 x -√2

These functions could be parallels to the line y=3/4 x +2/5

Answer:

see below.

Step-by-step explanation:

The key to this question is the factor 3/4. So anything that is going to make the coefficient in front of x = to 3/4 is a possible answer.

y = 3/4x + b  where b is anything but 2/5 is one answer. Disguised but still likely is

4y = 3x + b        Where you could divide everything by 4

y = 3/4x + b/4

Even something like

-4y = - 3x + b  is possible because when you divide by -4, you get

y = -3x/-4 + b/-4

y = 3x/4 - b/4
