The number z and 0.8 are additive inverses. drag and drop 0.8 and z to their correct positions on the number line. drag and drop the label “sum” to the sum of 0.8 and z

we know that

If two numbers have a sum of zero, then we say they are additive inverses.

so

z+0.8=0 -------> the sum is equal to zero

z=-0.8------> the additive inverse of z is equal to -0.8

using a graph tool

see the attached figure

the answer Part a) and part b) in the attached figure

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

boxplot e is the answer
