X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
Answer:
Slope:
y-intercept: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
The slope can be found with the following formula:

In this case you can say that:

Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:

By definition, the line intersects the y-axis when the value of "x" is 0.
Notice in the table that when
, 
Therefore, the y-intercept is:

So we know he made 4,650 of sales and we need 2.5% of that
First to find 2.5% of 4650 we could do
x/4650 = 2.5/100
Cross multiply to get
100x = 11625
x = 116.25
So his salary for this week would be 225 + 116.25 = 341.25
The answer is like this!
the total number of marbles all together is 25, so that would be the denominator.
blue: 6/25- simplified= already in simplified form
red:10/25- simplified= 2/5
green:9/25- simplified= already in simplified form
so the answer to your question is 2/5.
hope this helped!!
It would be A=18 because of the equation a^2+b^2=c^2.
