F(x)......ur output = 19
19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0
2x + 7 = 0
2x = -7
x = -7/2
x - 2 = 0
x = 2
I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
Answer:
Ratio of Able's score to Ben=6:1
Ratio of Ben's score to Cal's=1:2
Ratio of able's score to ben;s score to cal's score=6:1:2
Step-by-step explanation:
Let Ben's score =x
Able scored six times Ben's score
Able=6*x
=6x
Cal scored a third of Able's score
Cal=1/3 of 6x
=1/3(6x)
Ratio of Able's score to Ben
6x:x
=6:1
Ratio of Ben's score to Cal's score
x:1/3(6x)
=x:6x/3
=x:2x
=1:2
Ratio of able's score to ben;s score to cal's score=6:1:2
Answer:
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Step-by-step explanation:
we have

Divide the compound inequality into two inequalities
-----> inequality A
-----> inequality B
Solve inequality A

Subtract 28 both sides

Divide by 4 both sides

Rewrite

Solve the inequality B

Subtract 28 both sides

Divide by 4 both sides

therefore
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Answer:
To find the inverse of:

Set the function to y:

Rearrange to make x the subject:






Swap x and y:

Change y to the inverse of the function sign:


Rewrite g(x) as a fraction:





Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other
