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

Concept:

When two lines are perpendicular to each other, their slopes are negative reciprocals.

The reciprocal of a number is 1 divided by the number.

In other words, it is the image opposite of a term.

Solve:

Given information

Given line = y = 2x - 5

Point = (-4, 4)

Find the slope of the line

Given the line is perpendicular to the line y = 2x - 5, the slope of the line would be negative reciprocal of the line y = 2x - 5.

Slope of line [y = 2x - 5] = 2

Slope of new line = (-1/2)

Find the y-intercept by substituting the given point

Equation of the new line: y = (-1/2)x + b

y = (-1/2)x + b

4 = (-1/2) (-4) + b

4 = 2 + b

4 - 2 = 2 + b - 2

b = 2

Finalize the equation of the line

Slope = -1/2

Y-intercept = 2

[tex]\boxed{y=-\frac{1}{2}x+2 }[/tex]

Step-by-step explanation:

1) 3 + 4*2*29 = 3 + 232  = 235  

First we have to do multiplication and then we have to add

2) 5n + 1

Term 1 ; n = 1  ;  5n + 1 = 5*1 + 1 = 5 + 1 = 6

Term 2 ; n = 2 ; 5n + 1 = 5*2 + 1 = 10 + 1 = 11

Term 3 ; n = 3 ; 5n+ 1 = 5*3 + 1 = 15 + 1 = 16

Term 4; n = 4  ; 5n + 1 = 5*4 + 1 = 20 + 1 = 21

The sequence : 6 , 11, 16 , 21 ..........

Answer: 2/25

Step-by-step explanation: Since we are replacing the marbles, these two events are independent which means that the outcome of the first does not affect the outcome of the second.

First find the probability of selecting a blue marble.

There are 2 favorable outcomes, the blue marbles,

and 10 possible outcomes, all the marbles in the bag.

So the probability of selecting a blue marble is 2/10 or 1/5.

Always reduce when finding probability

Now we find the probability of selecting a green marble.

There are 4 green marbles and 10 total so the probability of

selecting a green marble is 4/10 or 2/5.

Now we multiply the probabilities.

So we have 1/5 x 2/5 or 2/25.

the answer is 7/9. ...........

Answer: about 15 because 14x7=78 and 2 cups for every 14 so 7x2 is 14 and there is 6 remaining so 15 is about right

12 cups of sugar needed.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

for 14 lemons= 2 cups of sugar need.

for 1 lemon= 2/14 cups of sugar need.

Now, for 84 lemons

=84*2/14

=6*2

=12 cups of sugar need.

Hence, 12 cups of sugar needed.

Answer:

I have taken out the value of xyz.

Answer:

Both numbers = 27

Step-by-step explanation:

( x + x + 49 + 25 + 42)/ 5 = 34          Multiply both sides by 5

(2x + 49 + 25 + 42) = 34*5 = 170     Combine the left

(2x + 116) = 170                                 Remove the brackets.

2x + 116 = 170                                   Subtract 116 from both sides

2x = 170 - 116

2x = 54                                             Divide by 2

x = 54/2

x = 27

Check

27 + 27 + 49 + 25 + 42

170 / 5 = 34

It does check out.

27 is right.

In geometry, transformations are used to move a point or points from one position to another. The notation that describes how the blue function is transformed into the red function is -f(x)

I have attached the graph of both functions.

From the attached graph, we can see that the blue function is reflected over the x-axis to produce the red function.

Let:

[tex]f(x) \to[/tex] Blue

[tex]g(x) \to[/tex] Red

The transformation of reflection across the x-axis is:

[tex]g(x) = -f(x)[/tex]

Hence, the notation that describes how the blue function is transformed into the red function is -f(x)

Answer:

4^2 * 4^8 = B)4^10

Step-by-step explanation:

When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

We have to given that;

Number line is shown in figure.

And, The point A is at - 7 on number line.

The point D is at 8 on number line.

Hence, We get;

The length of AD on the number line is,

⇒ AD = | - 7 - 8 |

⇒ AD = | - 15 |

⇒ AD = 15
