What’s the rule for the translation (x,y) (x+3,y+7)

Answers

The rule would be right 3, since the algebraic composition is changing the x values, and up 7, since the y values are being changed. Whenever a number is being added to the x in the coordinate, the function is being moved to the right. When a number is subtracted from the x, then the function is moving left. 
For the y value, if you are adding a number to the y coordinate, you are moving it up, whereas when you subtract a number, you are moving it down that amount. 

Which operation flips the graph of a function over the x-axis?


A. Multiplying the function by –1
B. Multiplying the function by 1
C. Subtracting 1 from the function

Answers

A. multiplying the function by -1

Multiplying the function by –1 is the  operation flips the graph of a function over the x-axis

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The operation that flips the graph of a function over the x-axis is multiplying the function by -1.

When a function is multiplied by -1, the y-values are negated, which causes the graph to reflect over the x-axis.

if we have a function f(x) = x², the graph will be a parabola that opens upwards.

However, if we multiply this function by -1 to get -f(x) = -x², the graph will be the same parabola reflected over the x-axis and opening downwards.

Hence, Multiplying the function by –1 is the  operation flips the graph of a function over the x-axis

On the first day of summer a rainstorm brought 2.29 inches of rain to the area. During the rest of the summer there was 3 times as much rain as on the first day. What was the total number of inches of rainfall for the summer?

Answers

To solve this problem, we simply have to multiply the original inches of rain to that of how many times it was for the rest of summer. So in this case, simply multiply 2.29 by 3, that is:

 

2.29 inches * 3 = 6.87 inches

 

Answer:

Divide.

(5 1/4)÷(−2 1/2)

Enter your answer as a mixed number, in simplified form, in the box. Please Explain your answer.

Answers

Before you can divide anything mixed numbers, you must first put it as an improper fraction so 5 1/4 will change into 21/4 because 5*4+1 is 21 and don’t forget the fraction so it would be 21/4, and -2 1/2 would change into -5/4 because -2*2+1 is -5 and if u add the fraction it would become -5/4. Now, the method I use is leave, change, flip, so I first leave the 21/4 in 21/4/-5/4 and I change the division sign into a multiplication sign, and I flip the -5/4 to -4/5, so your new equation now looks like, 21/4•-4/5. Now we have to multiply. Since we can cross simplify, you can cancel out both fours leaving you with 21/1•-1/5 and when u multiply across you get -21/5. When u simplify it to a mixed number, it should look like -4 1/5 because you see how many times 5 goes into 21 which is 4 times and it leaves u with a remainder of 1 because 21-20 is 1 and when ever u have a remainder, u have to keep a denominator of 5 so your final answer is: -4 1/5
Final answer:

To divide (5 1/4)÷(−2 1/2), convert the mixed numbers into improper fractions and then multiply by the reciprocal of the divisor. Simplify the result to get the quotient as -2 1/10.

Explanation:

To divide the given mixed numbers, (5 1/4)÷(−2 1/2), we first convert them into improper fractions.

5 1/4 can be written as (4*5 + 1)/4 = 21/4.

(−2 1/2) can be written as (-2*2 + 1)/2 = -5/2.

Now, we can divide the fractions by multiplying the reciprocal of the divisor: (21/4) * (-2/5) = (-21/4) * (2/5) = -21/10.

Finally, we simplify the result by dividing both the numerator and the denominator by their greatest common factor, which is 1. The simplified result is -21/10, which can be written as -2 1/10 as a mixed number.

The temperature rose 4 f every 90 minutes before noon and rose 2 f for every 45 minutes after noon are these rates equivalent

Answers

Yes, because the afternoon rate is just the morning rate split in half. Instead of checking the temperature every hour and a half, the temperature was checked every 45 minutes. And, the temperature rate was also split in half when the time was split in half. So basically, if the 2 degrees every 45 minutes was multiplied by 2,(both the time and the temperature) or if the 4 degrees every 90 minutes was divided by 2, (once again, both the time and the temperature) then, they would both be either 2 degrees every 45 minutes, or they would both be 4 degrees every 90 minutes.

0 + 1 = 1

so your answer is 1 1/x

Answer :  Option B is correct.

Explanation :

Since we have given that

f(x) = x+1

and

g(x) =x

and when we divide f(x) with g(x) i.e.

[tex]\frac{f(x)}{g(x)}[/tex]

And we know the division algorithm , i.e.

[tex]f(x)=g(x).q(x) +r(x)[/tex],

Where q(x) represents quotient and r(s) denotes remainder

So, we write it in this manner ,

[tex]x+1=x.1+1\\\\\text{Remainder becomes 1}[/tex]

Hence, Remainder = 1

So, Option B is correct.

holly and melanie were playing a video game. the ratio of holly's score to melanie's score was 8:3. after melanie scored 34 points, the ratio of their scores became 2:5. what were their scores at the end?

Answers

They started with a ratio of 8:3.
Since we don't know the actual numbers, let's say their scores were originally 8x for Holly and 3x for Melanie.
Then Melanie scored 34 points, so her score became 3x + 34.
Holly's score remained the same at 8x.
The new ratio is 2:5, so

8x/(3x + 34) = 2/5

Now we solve the equation for x.

40x = 6x + 68

34x = 68

x = 2

With x, we can find the scores.

Holly ended up with 8x = 8 * 2 = 16
Melanie ended up with 3x + 34 = 3(2) + 34 = 40

The sum of two numbers is 39 . the larger number is 17 more than the smaller number. what are the numbers?

Answers

Larger Number + Smaller Number = 39
Larger Number = S + 17
Smaller Number = S

S + 17 + S = 39
2S + 17 = 39
2S = 39 - 17
2S = 22
S = 22/2
S = 11

Larger Number is S + 17
Larger Number is 11 + 17

Larger Number is 28
Smaller Number is 11
Final answer:

The smaller number is 11 and the larger number is 28.

Explanation:

Let's assume the smaller number is 'x'.
The larger number is 17 more than the smaller number, so the larger number can be represented as 'x + 17'.
The sum of the two numbers is 39, so we can set up the equation: x + (x + 17) = 39.
By simplifying the equation, we get 2x + 17 = 39.
Subtracting 17 from both sides gives us 2x = 22.
Dividing both sides by 2 gives us x = 11.
So, the smaller number is 11 and the larger number is 11 + 17 = 28.

Which unit fraction should be used to convert 15 inches to centimeters?

Answers

Answer:  ([tex] \frac{2.54 cm}{1 in} [/tex])  .
Final answer:

To convert from inches to centimeters, the unit fraction used is 2.54 cm/1 in. Therefore, 15 inches is equal to 38.1 centimeters.

Explanation:

To convert a measurement from inches to centimeters, we utilize a unit conversion factor. In this instance, the unit conversion factor we're interested in relates inches to centimeters. One inch is equivalent to 2.54 centimeters. Hence, the unit fraction used for such conversion is 2.54 cm/1 in.

To determine the equivalent value in centimeters for 15 inches, we multiply the number of inches (15) by our unit conversion factor (2.54 cm/1 in). This gives us the following

15 inches * 2.54 cm/1 in = 38.1 cm.

So, 15 inches is equivalent to 38.1 centimeters when converted.

M(8, 5) is the midpoint of JK. The coordinates of point J are (5, −6) . What are the coordinates of point K?

Answers

11,16 I believe cause 8-5 is 3 it's increase by 3 8+3 is 11 -6+11 is 5 5+11 is 16

The midpoint is the exact middle of a line segment which divides the line into two equal lengths. Hence, the coordinate of K is (11, 16)

We can obtain the distance between the coordinates of JM thus :

Distance = y2 - y1 ; x2 - x1

Distance = (8 - 5) ; (5 - (-6) = (3, 11)

Hence, the change in the coordinates is (3, 11)

Therefore, the coordinates of K can be obtained thus :

(8 + 3) ;(5 + 11) = (11, 16)
