Y = 8

Explanation:

X = 10

5x - 4y = 18

5(10) - 4y = 18

50 - 4y = 18

50 - 4y = 18
-50 -50

-4y = -32

-4y/-4 = -32/-4

y = 8

B) should be your answer

The first one (the one given), is 6 "points" (forgot what it's called sorry) from 0 on all sides. To dilate it 1/3, divide 6 and 3

6/3 = 2

The one's that have points that land on points with 2 in it is B

so B is your best answer

hope this helps

Answer:

It is the distance that - 5 is from 0 on the number line.

Step-by-step explanation:

We have to select a statement that is true about the value of StartAbsoluteValue negative 5 EndAbsoluteValue i.e. |- 5|

Definition of the absolute value function is given by, |x| = x for, x ≥ 0 and |x| = - x for x < 0.

Now, an absolute value function gives the positive value of any value in the function i.e. |- 5| = 5.

Therefore, it is the distance that - 5 is from 0 on the number line. (Answer)
