A horizontal line passes through the point (5, -1). Which point is also on this line?
NikAS [45]

Step-by-step answer with explanations:

Recall that a coordinate pair such as (5,-1) has two components.

The first (5, -1) means that the point is situated at x=5.

The second (5, -1) means that the point is situated at y=-1.

Now, a <em>horizontal</em> line through (5,-1) means that ALL points on the line have y-coordinate equal to -1, so that any point with y=-1 will lie on this horizontal line.  An example would be (-2,-1).

A <em>vertical</em> line through (5, -1) means that ALL points on the line have x-coordinate equal to 5, so that any point with x=5 will lie on this vertical line.  An example would be (5,4).

Answer:

Discriminant = 84

The polynomial has two real distinct roots

Step-by-step explanation:

Given: f(x)=3x^2+12x+5

To find: discriminant of the given function and number of distinct real zeros

Solution:

For a polynomial f(x)=ax^2+bx+c , discriminant is given by D=b^2-4ac

If D>0, then the polynomial has two real and distinct roots.

If D=0 then the polynomial has two real and equal roots.

If D<0 then roots are not real.

Here, in f(x)=3x^2+12x+5

a = 3, b = 12 and c = 5

D=(12)^2-4(3)(5)=144-60=84

As D > 0, the polynomial has two real distinct roots.

16% - x grams
84% - 21 grams

16:x = 84:21
84x = 16×21
4x = 16
x = 4

One should consume 21 + 4 = 25 grams of fiber daily.
