Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. .
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
D>0 the roots are real and unequal
Function (2)
D<0 the roots are real and unequal
Function (3)
D>0 the roots are real and unequal
Function (4)
D>0 the roots are real and unequal
Function (5)
D<0 the roots are real and unequal
Function (6)
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
Answer:
t = 3c - 5
Step-by-step explanation:
The relation between c and t is linear as the increase of the value of t is uniform for each unit increase in the value of c.
Now, any two points on the graph of the t = f(c) equation are sufficient to determine the equation.
Let the points are (2,1) and (3,4).
So, using two points formula of straight line we get the equation is
⇒ t - 4 = 3(c - 3)
⇒ t - 4 = 3c - 9
⇒ t = 3c - 5 (Answer)
Answer:
The total number of adults will be: 120 adults
Step-by-step explanation:
Given that there were 24 adults and 10 children in a game.
Thus, adults to children ration = 24:10 or 24/10
- If there were 50 children, how many adults would be at the game?
Let 'x' be the number of adults when there 50 children.
so the ration of adults 'x' to 50 childern = x: 50 or x / 50
As the ratio is the same.
Thus,
24 : 10 = x : 50
24/10 = x/50
switching sides
x/50 = 24/10
x = 24/10 × 50
x = 120 adults
Therefore, the total number of adults will be: 120 adults
Answer:
ok
Step-by-step explanation:
ok
First you have to get the same variables on one side so you’d subtract 5.1w from both sides, making the equation -0.6w = -30
then you want to single out the variable, diving -0.6 on both sides making the new equation and the answer w = 50
hope this helps!
