f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
Answer:
f(x) = x – 4
checking for all the functions by replacing x as 3
f(x) = 4 – x
f(3) = 4 - 3
f(3) = 1
does not match
f(x) = –4x
f(3) = -4(3)
f(3) = -12
does not match
f(x) = x + 4
f(3) = 3 + 4
f(3) = 7
does not match
f(x) = x – 4
f(3) = 3 - 4
f(3) = -1
matches
Answer:
f(x) = x - 4
Step-by-step explanation:
The options are:
f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
For f(x) = 4 – x, when x=3, f(x)=1 so it cannot be right.
For f(x) = –4x, when x=3, f(x)=-12 so it cannot be right either.
f(x) = x + 4, when x=3, f(x)=7 so it cannot be right.
The only choice left which is also the right answer is f(x) = x – 4

Question:. Francisco has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater. He needs 112 points for a free movie ticket. How many visits must Francisco make to earn a free movie ticket?
Find out: How many visits required for 112 points.
Solution: Let's make an equation
=> 55 + 9.5x = 112
Let's make x the subject of formula
=> 9.5x = 112 - 55
Substract 55 from 112
=> 9.5x = 57
Divide both sides by 9.5
=> [tex] \frac{9.5x}{9.5} = \frac{57}{9.5} [/tex]
Divide
=> x = 6
Therefore Francisco needs 6 visit to earn a free movie ticket
The number of visits Francisco must make to earn a free movie ticket is 6.
Given that, Francisco receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater.
Let the number of visits to the movie theater be x.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
He needs 112 points for a free movie ticket.
Now, the equation is [tex]9.5x+55=112[/tex]
[tex]9.5x=112-55[/tex]
[tex]9.5x=57[/tex]
[tex]x=\frac{57}{9.5}[/tex]
[tex]x=6[/tex]
Therefore, the number of visits Francisco must make to earn a free movie ticket is 6.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (5, 5) and ( 7, 1).
Answer:
x -2y = 0
Step-by-step explanation:
A perpendicular bisector is a line perpendicular to a given line or segment that goes through the midpoint between given points. The perpendicular line will have a slope that is the opposite reciprocal of the slope of the segment between the given points.
__
The midpoint between A and B is ...
M = (A +B)/2
M = ((5, 5) +(7, 1))/2 = (12, 6)/2 = (6, 3)
The slope of the line between A and B is ...
m = (y2 -y1)/(x2 -x1)
m = (1 -5)/(7 -5) = -4/2 = -2
__
The opposite reciprocal of the slope of the given segment is ...
m' = -1/-2 = 1/2
The point-slope form of the equation of the perpendicular bisector can be written as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -3 = 1/2(x -6) . . . . line with slope 1/2 through point (6, 3)
Multiplying by 2 gives ...
2y -6 = x -6
Subtracting (2y -6) gives the standard-form equation ...
x -2y = 0

If x2 mx m is a perfect-square trinomial, which equation must be true?.
Expression consist of numbers, variables, and mathematical operations. The equation that is true is x²+mx+m= (x+2)².
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that the x²+mx+m is a perfect square trinomial, and we know that the general equation of perfect square trinomial is given as,
ax²+bx+c=0
where a,b and c are real numbers, and a≠0,
if we compare the equation with our equation
[tex]ax^2+bx+c=0\\x^2+mx+m=0[/tex]
We will get the value of 'a' as 1, b=c=m, therefore, we need a binomial which is when expanded then in its perfect square trinomial the value of b=c, therefore, the only feasible option here is (x+2)².
Hence, the equation that is true is x²+mx+m= (x+2)².

What is the sign of f on the interval - 6
Answer:
Step-by-step explanation:
f ( - 7 ) = [ 2 ( - 7 ) - 3]( - 7 + 6 )[ 5 ( - 7 ) + 6 ] = ( - 17 )( - 1 )( - 29 ) < 0 , Negative
f ( - 5 ) = [ 2 ( - 5 ) - 3]( - 5 + 6 )[ 5 ( - 5 ) + 6 ] = ( - 13 )( + 1 )( - 19 ) > 0 , Positive
f ( - 1 ) = [ 2 ( - 1 ) - 3]( - 1 + 6 )[ 5 ( - 1 ) + 6 ] = ( - 5 )( + 5 )( + 1 ) < 0 , Negative
The answer is (A) " f " is always POSITIVE
