x^2 = 100...by taking the square root of both sides, this eliminates the ^2
x = (+-) sqrt 100
x = (+-) 10
so the values of x are -10 and 10
120×90/100 = 12×9 = 108

Answer:

Step-by-step explanation:
Given
The attached graph
Required
Equations with higher unit rate
First, calculate the unit rate of the graph

Where:


So:



For the given options.
The unit rate is the coefficient of x
So: 
Going by the above definition of unit rate.




















The unit rates grater than the graph's from small to large are:


-625
use long multiplication to evaluate .
Showing fractions can be expressed in model and number line.
Using a model, you have to draw the number of parts (denominator) and shade the number of parts (numerator).
Using a number line, the line starts from 0 to the number of the denominator. You put a marker to the number that is the same as the numerator.
Both model and number line use the value of the numerator and denominator. What makes them different is how they are presented. Model can easily be understood compared to number line.
