8 hours
Step-by-step explanation:
it's increasing by 6 so at the end there's a reminder of 2.
3. A) y-intercept =5
Slope=(-4,10)
B) y=-4/10x+5
4. A) y-intercept=-1
Slope=(5,5)
B) y=5/5x-1
Answer:
c. This quadratic equation has two complex solutions.
Step-by-step explanation:
Of the choices ...
a. This quadratic equation has exactly one real solution.
b. This quadratic equation has two real solutions.
c. This quadratic equation has two complex solutions.
d. This quadratic equation has no solutions.
The one that is true is <em>c: two complex solutions</em>.
__
The discriminant of quadratic ax^2 +bx +c = 0 is ...
d = b^2 -4ac
For this quadratic, the value is 6^2 -4·5·2 = -4.
When the discriminant is positive, there are two distinct real solutions.
When the discriminant is zero, there is one real solution.
When the discriminant is negative, there are two complex solutions. The discriminant of this quadratic is negative, so there are two complex solutions.
Answer: The answer is: " 2 " .

→ Kami has read the book "<u> 2 (two) </u>" times.
_______________________________________________
Step-by-step explanation:
_______________________________________________
Let "J" represent the number of times julia has read the book.
Let "K" represent the number of times Kami has read the book.
J = 6 ;
J = 3K ;
Solve for "K" ;
J = 6 = 3K ;
→ 6 = 3K ;
↔ 3K = 6 ;
Divide each side of the equation by "3" ;
to isolate "K" on one side of the equation; & to solve for "K" :
→ 3K / 3 = 6 / 3 ;
to get:
K = 2 .

Answer:
No
Step-by-step explanation:
y^2 = x^2 + 5
Rewriting
y^2 - x^2 = 5
This is a hyperbola
We can use the vertical line test to show that it is not a function since a vertical line passes through more than one point.
