Answer:17.14%
Step-by-step explanation:
145 x
_____=_____
175 100
145(100)=175(x)
14500=175x
__________
175 175
x=82.86
100-82.86=17.14%
If I'm reading your question correctly: "<span>F(x)=7x+9/8x-9 when -f(x)," then all you have to do to find -f(x) would be to put a negative sign in front of ALL
of 7x + 9 / (8x-9):
9
- f(x) = -7x - --------
8x-9</span>
Answer:
-5.5 4.5
Step-by-step explanation:
Given:
The numbers to order from least to greatest is given as:
In order to compare these numbers, we have to convert them in same form.
Let us simplify each number in decimal form.
So, the least number is one which has the largest value with a negative sign.
Here, -5.5 is the least number.
The next smallest number is -4.47. So,
The next smallest number is 2. So,
The next smallest number is 3.14. So,
The greatest number is 4.5.
Therefore, the order from the least to greatest is:
-5.5 < < < < 4.5
I don't understand what you mean by 'mentally' but anyways, here is how to solve it.
(z−12)(z+12)
=(z+−12)(z+12)
=(z)(z)+(z)(12)+(−12)(z)+(−12)(12)
=z^2+12z−12z−144
=z^2−144
