Y= y1

replace the y1 with the ordinate ( the y-part) of the point you are going thru

example a horizontal line going through the point (7,12) would be y=12

PLEASE HELP idk what any of this means. 25 points

Answer:

Step-by-step explanation:

A dilation is something that enlarges or shrinks an existing figure, retaining all angle measures. The two figures will be similar, not congruent.

A dilation of 1/2 (which is less than one) will make a figure smaller. You divide each coordinate point by two

(x, y) → ( $\frac{1}{2}x, \frac{1}{2}y$ )

39= 3m - 12<br><br> I'd really appreciate it if you showed your work.

expeople1 [14]

To solve for m;

39 = 3m -12

39+12 = 3m -12 + 12 (add 12 to both sides)

51 = 3m

51 ÷ 3 = m

17 =m

m =17

Hope that helps, let me know if you don't understand something :D

Answer: $4.14 \times 10^9$

Explanation:

Place the decimal point between the first two digits to get 4.14

Now ask yourself: How many places must we move the decimal point to go from 4.14 back to 4,140,000,000?

The answer is 9 places to the right.

This means we'll have 9 as the exponent over the 10

$4,140,000,000 = 4.14 \times 10^9$

Claire had 4 1/6 feet of string. She used some string to hang out decorations. Now she has 1 5/6 feet of string left. How much s

vodka [1.7K]

Answer:

Length of string used by Claire = 7 / 3 feet

Step-by-step explanation:

Given:

Length of string Claire in starts = $4\frac{1}{6}$ feet

Length of string Claire in end = $1\frac{5}{6}$ feet

Find:

Length of string used by Claire

Computation:

Length of string Claire in starts = $4\frac{1}{6}$ feet = 25 / 6 feet

Length of string Claire in end = $1\frac{5}{6}$ feet = 11 / 6 feet

Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end

Length of string used by Claire = [25 / 6] - [11 / 6]

BY taking LCM

Length of string used by Claire = [25 - 11] / 6

Length of string used by Claire = 14 / 6

Length of string used by Claire = 7 / 3 feet
