The discriminant is a quick way to determine the quantity and type of the possible solutions of a quadratic equation. If the dis

criminant has a value of -28, what can we conclude about the solution(s) to the equation? There are two real solutions to the quadratic equation. There is only one real solution to the quadratic equation. There are three real solutions to the quadratic equation. There are no real solutions to the quadratic equation.

4 0

Step-by-step explanation:

3x2 -5x+1=0

Quadratic eq ax2 +bx+c=0

Discriminant=b2 -4ac

=(-5)2 -4*3*1

=25-12

=13>0 so 2 solutions.

Line m in xy plane contains the points (2,4) and (0,1) which of the following is the equation of M
HACTEHA [7]

Answer:

The equation of line M in slope intercept form is    y=\frac{3}{2}x+1

The equation of line M in standard form is  3x-2y=-2

Step-by-step explanation:

step 1

Find the slope of line M

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(2,4) and (0,1)

substitute

m=\frac{1-4}{0-2}

m=\frac{-3}{-2}

m=\frac{3}{2}

step 2

Find the equation of the line M in point slope form

y-y1=m(x-x1)

we have

m=\frac{3}{2}

point\ (0,1)

substitute

y-1=\frac{3}{2}(x-0)

y-1=\frac{3}{2}x ----> equation in point slope form

step 3

Find the equation of line M in slope intercept form

y=mx+b

Isolate the variable y in the equation of the line in point slope form

y-1=\frac{3}{2}x

Adds 1 both sides

y=\frac{3}{2}x+1

step 4

Find the equation of the line M in standard form

Ax+By=C

where

A is a positive integer

B and C are integers

we have

y=\frac{3}{2}x+1

Multiply by 2 both sides

2y=3x+2

3x-2y=-2 ---> equation in standard form

If i have 480 grams of pasta for 4 people how many kilograms will i need for 14 people
Afina-wow [57]

\bf \begin{array}{ccll} \stackrel{pasta}{grams}&people\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 480&4\\ g&14 \end{array}\implies \cfrac{480}{g}=\cfrac{4}{14}\implies \cfrac{480}{g}=\cfrac{2}{7} \\\\\\ \cfrac{480\cdot 7}{2}=g\implies 1680=g

now, there are 1000 grams in one Kilogram, so in 1680 grams, there are 1680/1000 Kilograms, namely 1.680.
