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

The temperature in a particular city to decrease at a constant rate of 3°F per hour.

An equation is an expression that shows the relationship between two or more numbers and variables.

At 2:00 a.m., the temperature was 54 degrees Fahrenheit, and at 5:00 a.m., the temperature was 45 degrees Fahrenheit. Hence:

Rate of change = (45°F - 54°F) / (5 - 2) = -3

Answer:

see explanation

Step-by-step explanation:

given

(2x + 5)(2x - 1) ← expand using FOIL

(a)

= 4x² - 2x + 10x - 5 ← collect like terms

= 4x² + 8x - 5

(b)

using the method of completing the square on

4x² + 8x - 5 ← factor out 4 from the 1st 2 terms

= 4(x² + 2x) - 5

to complete the square

add/ subtract ( half the coefficient of the x- term )² to x² + 2x

= 4(x² + 2(1)x + 1 - 1) - 5

= 4(x + 1)² - 4 - 5

= 4(x + 1)² - 9

Answer:

Step-by-step explanation:

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

Answer:

x = 12 , y = 60

Step-by-step explanation:

The figure has 2 pairs of parallel sides and is therefore a parallelogram.

The opposite sides and opposite angles are congruent , then

x + 3 = 15 ( subtract 3 from both sides )

x = 12

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
