Find the inverse of the given function.
(f) = -5x-9​

Answer:

The equation of the line is 4y = -x + 19

Step-by-step explanation:

Firstly, we need to get the slope of the line;

Since it is through two points; we have the slope as;

y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4

Mathematically, we can write the equation of a straight line line as;

y = mx + c

So we have;

y = -1/4x + c

y = -x/4 + c

To complete the equation, we need the value of c.

we can choose any of the points and insert the x and y value

Thus;

3 = -7/4 + c

c = 3 + 7/4

c = 19/4

So our equation becomes;

y = -x/4 + 19/4

Multiply through by 4

4y = -x + 19

Answer:

y-3= -1/4 x (x-7)

Step-by-step explanation:

Find the slope of the line between  

( 7 , 3 )  (7,3)  and  ( − 1 , 5 )  (-1,5)  using  m = y 2 − y 1 x 2 − x 1

m=y2-y1x2-x1 , which is the change of  y/ y  over the change of  x/ x .

Answer:

4 Months, and the Total amount is 280

Step-by-step explanation:

60 + 55m = ?

200 + 45m = ?

60 + 55 = 115 + 55 = 170 + 55 = 225 + 55 = 280

200 + 45 = 245 + 45 = 290 + 45 = 235 + 45 = 280

The unit cost of one wing of chicken is: $38.40/24 = $1.6.

Unit cost can be defined as the cost of one unit of a quantity, that is, how much can by a unit measure of whatever is being sold.

To find the unit cost, divide the total cost over the number of unit items.

Cost of 24 chickens = $38.40

Unit cost = $38.40/24

Unit cost = $1.6.

Answer:

k =-2

Step-by-step explanation:

Using the slope formula

( y2-y1)/(x2-x1) = m

( k- -1)/( -10 - -8) = 1/2

( k+1)/ ( -10+8) = 1/2

( k+1) /-2 = 1/2

Multiply each side by -2

( k+1) /-2 * -2 = 1/2 * -2

k+1 = -1

Subtract 1 from each side

k+1-1 = -1-1

k = -2

Answer:

K= -5 because -10 divided by -5 which is K gives u 2

Answer:

Given that only the first digit and a range of four possible numbers for the second digit of the four digit pin number are remembered, the number of different possible combinations are 400 (possible combinations)

Step-by-step explanation:

The given information are;

The number of digits contained in the pin = 4 digits

The number of digits that can be the first number = 1 (given that the first digit is 4)

The number of digits that can be the second number = 4 (6, 7, 8, or 9)

Therefore, we have;

The number of digits that can be the third number = 10 (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9)

Similarly, the number of digits that can be the fourth number = 10

Therefore, the total number of possible combinations are;

1 × 4 × 10 × 10 = 400 possible combinations.

2x + 9 - 17x - 15 - x =????

2x - 17x - x + 9 - 15 = 0

- 15x - x - 16 = 0

- 16x - 16 =0

-16x = 16

x = 16 / - 16

x = 1

Answer:

1.) x = 37

2.) m<SVW = 74 deg

3.) m<TWV = 106 deg

Step-by-step explanation:

Linea SY and TZ are shown to be parallel.

Angles SVW and TWV are same-side interior angles.

Theorem:

If parallel lines are cut by a transversal, then same-side interior angles are supplementary.

m<SVW + m<TWV = 180 (by the definition of supplementary angles)

2x + 3x - 5 = 180

5x - 5 = 180

5x = 185

x = 37

m<SVW = 2x = 2(37) = 74

m<TWV = 3x - 5 = 3(37) - 5 = 111 - 5 = 106

Answer:

1.) x = 37

2.) m<SVW = 74 deg

3.) m<TWV = 106 deg

9514 1404 393

Answer:

Step-by-step explanation:

1. The conversion factor is given in gallons per cubic foot. So, to avoid more conversion factors than necessary, it is convenient to use feet as the unit of measure.

__

2. The dimensions are ...

  1 yd × 3 ft/yd = 3 ft . . . . length

  18 in × 1 ft/(12 in) = 1.5 ft . . . . height

So, the volume is ...

  V = LWH = (3 ft)(1 ft)(1.5 f) = 4.5 ft³

Then the number of gallons is ...

  (4.5 ft³)×(7.5 gal/ft³) = 33.75 gal

Answer:

lines are parallel

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines is - 1

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = 3, 1) and (x₂, y₂ ) = (8, 6)

m = [tex]\frac{6-1}{8-3}[/tex] = [tex]\frac{5}{5}[/tex] = 1 ← slope of line a

Repeat with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2,9)

m = [tex]\frac{9-1}{2+6}[/tex] = [tex]\frac{8}{8}[/tex] = 1 ← slope of line b

Since both slopes are equal, line a and line b are parallel

Answer:

The answer is B. Hope this helps!

Step-by-step explanation:

105 degrees is from a b to d and a b to c is 75 and 105 - 75 =30.

Answer:

30*

Step-by-step explanation:

If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.

75* + <CBD = 105*

-75*                  -75*

<CBD=30*

So that's how I got it.
