(x,y,z)=(-4,-2,-5)
I added some images for explanation
First draw a line on the smallest number, and one on the largest. then calculate the midpoint (n+1)/2 the value, and draw that line in the middle. calculate upper quartile and lower quartile and draw lines on them. draw a line between the tops of the quartiles and one between the bottom, and from the middle of the lines to the minimum and maximum. sorry if not explained well
We will assume that the number is n
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3
It looks right to me. you followed all the clues.
Answer:
a=13, b=7
Step-by-step explanation:
You can use the exponent rule

so
so
a-5=8
a=13
so
9-b=2
b=7
