For a quadratic of the form
, we have the quadratic formula
,
where a is the coefficient (number before the variable) of the squared term, b is the coefficient of the linear term, and c is the constant term.
So, given
, we can get that
, and
. We substitute these numbers into the quadratic formula above.
This is our final answer.
If you've never seen the quadratic formula, you can derive it by completing the square for the general form of a quadratic. Note that the
symbol (read: plus or minus) represents the two possible distinct solutions, except for zero under the radical, which gives only one solution.
I didnt have room for 7 so ill just write it here
20O-12x<60
-12x<-140
X>11.6666..or 11 2/3
Answer:
D) X = 11
Step-by-step explanation:
Solve for x
5x + 2 = 59
subtract 2 from both sides
5x = 57
divide both sides by 5
x = 57/5
this answer would be closest to x = 11 (11* 5 = 55)
Answer:
A
Step-by-step explanation:
Because
Answer:
y=4x
Step-by-step explanation:
Given : x represent the number of television show episodes that are taped in each seasons
To Find : write an expression for the number of episodes taped in 4 seasons
Solution:
Let number of episodes taped in 4 seasons be y
Number of the episodes taped in 1 season = x
So, number of episodes taped in 4 seasons :
y= 4x
Hence the required expression for the numder of episodes taped in 4 seasons :y= 4x
