Hi!

Positive discriminants will give you two solutions.

Discriminants equal to zero will give you one solution.

Negative discriminants will give you no solutions.

In a graph, the number of solutions is where the graph crosses the x-axis.

In the first graph, we can see it intersects the graph at two points: (2, 0) and (6, 0). Since there are two solutions it is a positive discriminant.

In the second graph, we can see it intersects at one point: the origin, or (0, 0). Since there is one solution it is a discriminant equal to zero.

In the third graph, we can see it doesn't intersect; it is above the x-axis. Since there are no solutions it is a negative discriminant.

What is the domain and range , and is it a function ?

dem82 [27]

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

:)))) solve the following by factorizing: x^2-2x=120

stepladder [879]

Answer:

Step-by-step explanation:

$x^2 - 2x = 120\\x^2 - 2x - 120 = 0$

We have to find the factors of 120 that can either add up to or have a difference of 2.

The factors of 120 are:

$\pm 1, 120, 2, 60, 3, 40, 4, 30, 5, 44, 6, 20, 8, 15, 10, 12...$

The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:

$(x+10)(x-12)$

The rectangular ground floor of a building has a perimeter of 780 ft. The length is 200 ft more than the width. Find the length

ivolga24 [154]

Answer:

L = 295ft

W = 95ft

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

If the length is 200 ft more than the width, then:

L = 200+W

Substitute

P = 2(200+W+W)

780 = 2(200+2W)

780 = 400+4W

4W = 780-400

4w = 380

W = 380/4

W = 95ft

Since L = 200+w

L = 200+95

L = 295ft
