What is the absolute value of -8 and 8?

Because taking an absolute value of a number means making positive, then we can conclude that the absolute value of both numbers are 8.

|-8| = 8
|8| = 8

Step-by-step explanation: The absolute value of an integer is its distance from zero on a number line. Since -8 is 8 units from zero, the absolute value of -8 is +8. Notice that I put the "+" in front of 8 to show that it's positive.

On the other hand, 8 would also be 8 units from zero so the absolute value of 8 would also be +8.

Write an equation that represents the line.<br> Use exact numbers.
Greeley [361]

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

   4y = 3x - 18    <------------------  FINAL ANSWER

-7-3 log₂ (-n + 10) = -16
SOVA2 [1]

Answer:

2

Step-by-step explanation:

-3 log₂ (-n + 10) = -16+7

-3 log₂ (-n + 10) = -9

log₂ (-n + 10) = -9/-3

log₂ (-n + 10) = 3

-n + 10 = 2^3

-n + 10 = 8

n=2
