roots of the given equation , 
Step-by-step explanation:
Given the equation: 
We can write this equation as:

A quadratic equation is in the form of
......[1] where a,b ,c are the coefficient and x is the variable,
the solution of the equation is given by;

On comparing given equation with equation [1] we get;
a = 3 , b = -4 and c =10
So, the solution of the given equation is given by;

or

or
[∴
Simplify:

therefore, the roots of the given equation are; 
False your answer is false

He made $394.76 washing 284 windows last week
This equation is put in slope-intercept form. That means it is in Y = mx+b.
m stands for the slope, and b stands for the y-intercept. So, in this case -9 is the B value, so -9 is the y-intercept.
