Ok i hope this helps and if it does pls give me brainliest!

So the longest line is 8 and makes a 90 degree angle with another smaller line which is labled 3.6. X is longer than 3.6 ( only by a little bit) But it looks like its half of the longest line (8). So i think the answer would be X equals 4. But i was thinking about it more i relized that you would prob just divide 8 by 3.6 which would be 2.22222 .... And that rounded tot he nearest 10th would be 2.2.

Answer:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)}

Step-by-step explanation:

recall that for a function to be valid, every input must give one and only 1 output. (i.e every x-ordinate must have only one unique corresponding y-ordinate)

I have highlighted in bold and underlined the entries for each of the other choices where an x-value gives more than one possible y-value, hence these are not functions. only the first option satisfies this condition:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)} Every x-value has a unique y-value, so it is possible that this is a function.

{(6, 6), (6, 8), (-8, -7), (-3, -8), (6,6),(6,8),(−8,−7),(−3,−8)} (not a function)

{(1, 8), (9, -3), (7, -4), (7, -6), (1,8),(9,−3),(7,−4),(7,−6)} (not a function)

{(-5, -1), (-3, -7), (-5, 3), (-7, -4), (−5,−1),(−3,−7),(−5,3),(−7,−4)} (not a function)

Leah cut a 7 inch ribbon into pieces that are 1/2 an inch long. How many pieces of ribbon did she cut?

14 ribbons.

7 divided by 1/2 is 14. dividing by a fraction or decimal is just like multiplying without the decimal point or numerator.

The image of the point (-6, -2)under a translation is (−7,0). Find the coordinates of the image of the point (7,0) under the sam

lesya692 [45]

Answer:

hello : solutio ( 6 ; 2)

Step-by-step explanation:

the translation is : x' = x + a ....(*)

y' = y + b ...(**)

calculate the coordinates ( a ; b) of vectro by the translation

you have : x' = -7 y' = 0 x = -6 y = -2

Substitute in (*) , (***) : -7 = -6 +a

0 = - 2 + b

a = -1 and b= 2

so : x' = x - 1

y' = y + 2

calculate now the coordinates of the image of the point (7,0) under the same translation.

x = 7 and b = 0

so : x' = 7-1 = 6 and y' = 0 + 2 = 2

the image is : ( 6 ; 2 )
