Hello : 
 20x²-39x+80=0
 a = 20   b = -39   c = 80
<span>
 the discriminant  b²-4ac  = (-39)²-4(20)(80)=1521-6400 = - 4879 </span><span>< 0 
 no solution in : R 
but in  C   </span><span> the product of the solutions of this equation is ; c/a = 80/20=4</span>

What’s the domain and range of this graph?
avanturin [10]

Given:

The graph of a downward parabola.

To find:

The domain and range of the graph.

Solution:

Domain is the set of x-values or input values and range is the set of y-values or output values.

The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.

Domain = R

Domain = (-∞,∞)

The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.

From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.

Range = All real numbers less than or equal to -4.

Range =  (-∞,-4]

Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].

A child wants to fill up a box with snow he can only carry the box if it weighs under 30 pounds the dimensions of the box are 30
Korolek [52]

Answer:

I thought that all races were = I thought it was fine we all loved each other and that there were protests. That the black lives matter. if a police officer kills a white man bc the white man is a threat then no one cares but if a police man kills a black man bc a black man is a threat everyone protests. I thought we were = but then black people are out there saying there lives matter. They do but white lives matter too so do blue lives and green lives and purple lives. Everyone matters but if you say that apparently you get in trouble. All lives matter but instead people had to make a program titled black lives matter.

One small tank takes twice as long to fill a tank as a larger pipe does. If it takes the two pipes 40 minutes to fill the tank w
Gala2k [10]
Um... it'll take each pipe 80 mins, bcz if together they take that long, then to find the pipes time separately, you just multiply it by two to show it doing the work the other pipe did as well. Is that what you wanted??

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form
Elena L [17]

Answer:

\huge  \orange{y =  -  \frac{1}{9} x} \\

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have

y + 1 =  -  \frac{1}{9} (x - 9) \\ y + 1 =  -  \frac{1}{9} x + 1 \\ y =  -  \frac{1}{9} x + 1 - 1

We have the final answer as

y =  -  \frac{1}{9} x \\

Hope this helps you
