E: (1 3/4, 4 1/4)
Number line usually helps a lot
Start at the first number and move to the left for subtracting and to the right for adding. Hope this helps.
Answer:
D
Step-by-step explanation:
I hope this correct and have a great day
Hey there! :)
2x - 3y - z ; When x = -2, y = 3, & z = -2
Since we're given the values of x, y, & z, we can very simply plug everything in!
2(-2) - 3(3) - (-2)
Simplify.
(-4) + (-9) + 2
Get rid of parenthesis.
-4 - 9 + 2
Remember to do PEMDAS!
Parenthesis
Exponents
Multuply
Divide
Add
Subtract
So, since adding comes before subtracting, let's add! :)
-4 - 9 + 2
-4 - 7
Simplify.
-11
So, our answer is [A] : -11
~Hope I helped!~
Given 2 numbers, a and b. The number exactly in the middle of a and b is

.
For example, the number exactly in the middle of numbers 5 and 17 is (5+17)/2=22/2=11.
Check: 11-5=6, 17-11=6
The number in the middle of 24 and 92 is (92+24)/2=116/2=58.
The positive difference between 58 and both 24 and 92 is :
58-24 = 34 & 92-58 = 34
Thus the height of a woman
x, can vary at most 34, from 58. That is the height of a woman can be 34 ft less or more than 58.
In absolute value notation this is expressed as :
|x-58|≤34
what this means is that
x-58≤34 or 58-x≤34
so x≤58+34 or -x≤34-58
x≤92 or -x≤-24, that is x≥24
Answer: |x-58|≤34 ; 24≤x≤92
