5 0

hello : <span>
<span>the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
</span>
if: Δ = 0 : : x1 =x2 = -b/2a      </span> (has a repeated solution)

Which is the graph of g(x)=10/x
Elan Coil [88]

Answer:

y=0

Step-by-step explanation:

Find where the expression  

10

x

is undefined.

x

=

0

Consider the rational function  

R

(

x

)

=

a

x

n

b

x

m

where  

n

is the degree of the numerator and  

m

is the degree of the denominator.

1. If  

n

<

m

, then the x-axis,  

y

=

0

, is the horizontal asymptote.

2. If  

n

=

m

, then the horizontal asymptote is the line  

y

=

a

b

.

3. If  

n

>

m

, then there is no horizontal asymptote (there is an oblique asymptote).

Find  

n

and  

m

.

n

=

0

m

=

1

Since  

n

<

m

, the x-axis,  

y

=

0

, is the horizontal asymptote.

y

=

0

There is no oblique asymptote because the degree of the numerator is less than or equal to the degree of the denominator.

No Oblique Asymptotes

This is the set of all asymptotes.

Vertical Asymptotes:  

x

=

0

Horizontal Asymptotes:  

y

=

0

No Oblique Asymptotes

The equation y = -20x + 275 represents the balance of Cassie's bank account y after x months. Which of the following statements
vagabundo [1.1K]

Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”

Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.

Have a nice day!
