Write a rule for the function that shifts every point in the plane 10 units down and 4 units to the right

Answer:

Substitute y with y+10 and x with x-4.

Step-by-step explanation:

To shift every point in the plane 10 down you have to substitute y with y+10 and to shift every point in the plane 4 units right you have to substitute x with x-4.

Suppose the origin of function on the plane is (0,0) now we have to make the origin (4,-10).

first (x,y)=(0,0)

When we substitute x and y

(x-4,y+10)=(0,0)

x-4=0    

x=4

y+10 = 0

y= -10

Now the origin is (4,-10).

Hence the function is shifted 10 units down and 4 units right.

Luis skates 2/3 mile from his home to school. Isabella skates 2/4 mile to get to school. Who skates father?
iogann1982 [59]
In order to figure out whether Luis or Isabella skates farther to get to school, we have to create a common denominator between the two fractions that represent the distance that each person walks.

The least common denominator of 3 and 4 is 12.  This means that we have to change both fractions into equal fractions with denominators of 12.

To figure this out, we must set up a proportion.
2/3 = x/12
To solve this proportion, we must cross-multiply the fractions.  We get:
24 = 3x
If we divide both sides by the coefficient of x which is 3, to get the variable x alone, we get:
x = 8

Therefore, 2/3 = 8/12, so Luis skates 8/12 mile from his home to school.

If we do the same process for the 2/4 mile to get to school for Isabella, we get 6/12, because both fractions are equal to 1/2.

Therefore, we know that Luis skates 8/12 mile to school and Isabella skates 6/12 mile to get to school.  Because they have the same denominator, we can just compare the numerators.  We know that 8 is greater than 6, thus Luis skates farther to get to school.

Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?
kap26 [50]
<h2>Answer :</h2>

  • Error (e) = 12 - 9 = $ 3

  • assumed value (a) = $ 9

\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}

  • \mathrm{ \% \: error =\dfrac{3}{9} ×100}

  • \mathrm{ \% \: error = \dfrac{1}{3} ×100}

  • \mathrm{ \% \: error = 33.33 \%}

Answer:

<em>D</em>

Step-by-step explanation:

Question:On Saturdays. Eve earns $14. per hour for yard work and charges an extra amount for supplies/gas money to get there. Look at the table. Choose the linear function f Eve can use to determine her pay, where x is in hours and f(x) is her pay in dollars.

Answer: <em>The answer would be D because she gets payed $14 and hour so you would plug the hours she work into the letter x</em><em>.</em>
