I suppose what makes this question annoying is that there is the question mark so what i'll do first is substitute the question mark with x. also, there are annoying parenthesis so we'll first eliminate the ones we don't need. now we just have to solve for x.
-3.4 + (-8 + 2) = (x + (-8)) + 2
adding a negative number is subtracting that number so x + (-8) = x - 8
-3.4 + 2 - 8 = x - 8 + 2
-3.4 -6 = x - 6
x = -3.4
make sure you are aware that the negative sign belongs to the number after it so -2 + 4 is not -(2+4) = -6 but rather 4 - 2 = 2.
let me know if you have any questions!
Answer:
2
Step-by-step explanation:
You are right as rain. You go to the x axis.
Find x = 3.5
f(3.5) is the y value of x = 3.5
f(3.5) = 2
It might help you a bit if you wrote it as a point (3.5,2)
Answer:
(a d)/(bc)
Step-by-step explanation:
a/b ÷ c/d
Copy dot flip
a/b * d/c
ad / bc
Okay, so as you may know the inside angles of a triangle always add up to 180! so you must first find x, so that means add up all equations to find x. your answer is 41
Answer:
Interquartile range
Step-by-step explanation:
Range = 32, 29
Median = -6, 3
Upper quatile = 2, 13
Interquartile range = 11, 23
==> Interquartile range has the greatest difference of 23-11 = 12
