Marina CMI [18]3 years ago

For this case we have a function of the formy = f (x)

Where:

f (x) = - 4x + 3

We must find the value of the function when the variable x is -5.

Then, substituting, x = -5

f (-5) = - 4 (-5) +3

We have that by sign law- * - = +

f (-5) = 20 + 3\\f (-5) = 23

Answer:

f (-5) = 23

ANSWER

f( - 5)=23

EXPLANATION

The given function is

f(x)=-4x+3

To find f(-5), we substitute x=-5 to obtain;

f( - 5)=-4( - 5)+3

We multiply out to obtain:

f( - 5)=20+3

We simplify to get,

f( - 5)=23

Alright so I find it much easier to divide fractions by doing keep, switch flip. U might not have been taught this but it’s very helpful. So keep the first number, switch the division sign into multiplication sign and flip the fraction (so the decominator is now the numerator and vice versa)

What’s the equation for A slope =2 through the point (2,1)?
Fiesta28 [93]

Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (2, 1) into the partial equation

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = 2x - 3 ← equation of line

Boots: $59.00, discount: 10 percent sales tax 5.5 percent
I am Lyosha [343]

Answer:

Total cost of boots = $56.02

Step-by-step explanation:

$59 x 0.90 = $53.10

$53.10 x 1.055 = $56.02

or

59 x 0.10 = 5.9

59 - 5.9 = $53.10

53.10 x 0.055 = $2.92 tax

$53.10 + $2.92 = $56.02
