You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts
2 roots means the discriminan is positive in other words
D>0
When the discriminan is 0, D=0 we have exactly one x-intercept.
Discriminan D=0
and finally, if the discriminan were negative
D=0
then there is no solution or root at all.

he/ she is right that's the answer
Answer:
= r
Step-by-step explanation:
First write down the equation they gave you:
l = Prt
You need to ask yourself what is being done to r. r in this case is being multiplied by two variable: P and t. To undo multiplication you divide, the set up for division:
I divided by the two numbers, so it would be easier. The P and T cancels out on the right and you are left with r. On the left, however, it stays the same because there are no like terms to solve with. You just leave as it is.
The result you get is:
Answer:
x + y = - 3
Step-by-step explanation:
The equation for standard form is Ax + By = C. Since there is an invisible 1 in front of both x and y, you can easily solve the problem by subtracting -1x from both sides to get 1x + 1y = -3 or x + y = -3
