Step-by-step explanation:
2x^2-7=9
2x^2=9+7
2x^2/2=16/2
(square root)x^2=(square root)8
x=2.87
I used this method because I don't know any other method.
Answer:
Step-by-step explanation:
The equation of a line can be easily found from the graph. First, find two points on the line that intersect points on the graph, then plot the changes in the two axis in this manner (change in y)/(change in x), or rise/run. Thus, the slope of this line is 5/3. Then, the b in y = mx + b is simply when the line intersects the y-axis, in this case -5. Thus, the equation of the line is
y = -5/3x - 5
