3/10 + 4/100 = ???

.

Answers

Answer:

34/100

Step-by-step explanation:

Answer:

17/50

Step-by-step explanation:

Hi!

How you want to go about this is first make the 3/10 into 30/100 to make it match up with 4/100.

You want the denominators to both be 100 so they match.

So you would do this by finding 10 x what gets you to 100.

You could eyeball it and see that 10 x 10 = 100 or go backwards (right to left horizontally) and divide 100 / 10 to get 10.

But now what we have is :

30/100 + 4/100

All you have to do is add the first numbers and simplify if possible.

30 + 4 = 34

So :

34/100

To simplify we can divide both numbers by 2 :

34/2

100/2

17/50

And that is our final answer.

I hope this helped!

The greatest common factor is 6. Thus means we divide every part of the expression by 6.

3. The point P(3,5) is rotated 90° clockwise

P'?
A. P'(-3,-5)
B. P’(5,-3)
C. P'(-5,3)
D. P'(5, 3)

Please :)

Answers

Answer:

New coordinates of  P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Step-by-step explanation:

When a point A(x, y) is rotated 90° clockwise around the origin, we flip x and y and reverse the sign of x.  

Thus,  

The rule to rotate a point A(x, y) after a rotation 90° counterclockwise around the origin is:  

A(x, y) → A'(y, -x)

In our case, the point P(3, 5) is rotated 90° clockwise about the origin. Thus, the coordinates of  P' will be:

A(x, y) → A'(y, -x)

P(3, 5) → P'(5, -3)

Therefore, coordinates of P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Answers

Answer:

A. y = -4x + 2  and  B. 2x + 2y = 6      

Step-by-step explanation:

A. y = -4x + 2        This is correct since the displayed picture shows a negative slope. Therefore, m is negative

B. 2x + 2y = 6       This is converted to     y = -x +3   So, it is also correct

C.  2x - y = 7           This is converted to y = 2x-7      So, it is not correct

D. y = 5                   Y value would have to always be at 5  So, it is not correct

Answer:

all values less than 5.5

Step-by-step explanation:

Given the inequality expression – 6 + 2y < 5

We are to find all the possible values of x

-6 + 2 y < 5

Add 6 to both sides

-6 + 2y + 6 < 5 + 6

2y < 11

Divide both sides by 2

2y/2 < 11/2

y < 11/2

y < 5.5

hence the possible values of y are all values less than 5.5

{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​

Answers

Given:

The set of ordered pairs is

{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}

To find:

Which relation has the same domain as the given relation?

Solution:

We know that, domain is the set of input values or x-values.

For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is

Domain={0.5, 1.5, 4.0, 6.5}

Similarly,

For {(1,5),(2,2),(-3,15),(-8,12)},

Domain = {1, 2, -3,-8}

For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},

Domain={0.5, 1.5, 4.0, 6.5}

For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},

Domain = {2, 5, 12, 15}

For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​,

Domain = {-1, -3, -6, -10}

So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.

Therefore, the correct option is B.

Which equations best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3)? O y = 2x +4 O 2x +y=24 Ov--x-4 O y = x + 2​

Answers

Answer:

The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

y = -1/2x - 2

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

In our case, we are given

The slope m = -1/2

Point (2, -3)

now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

[tex]y = mx+b[/tex]

-3 = -1/2(2) + b

-3 = -1 + b

b = -3 + 1

b = -2

now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation

y = mx + b

y = -1/2x + (-2)

y = -1/2x - 2

Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

y = -1/2x - 2
