Answer:

The inverse of f is [tex]f^{-1}[/tex] =  (x -2)/4  

Step-by-step explanation:

To find the inverse of f(x) = 4x + 2 , interchange the variables and solve for y.

   Rewrite f(x) = 4x + 2  as  x = 4y + 2  then solve for y

                                             x -2 = 4y

                                           (x - 2)/4 = y

Answer:

320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.

When dividing 320 into 8 equal groups, each group would contain 40.

We have to divide 320 into 8 equal groups.

Performing the division as

            8 | 320 | 40

                  320

             -_______

                  0

So, 320 ÷ 8 = 40

Therefore, when dividing 320 into 8 equal groups, each group would contain 40.

Answer:

b = (9 - 12c)/5 OR b = 9/5 - 12c/5

Step-by-step explanation:

5b + 12c = 9

Subtract 12c from both sides.

5b = 9 - 12c

Divide both sides by 5.

b = (9 - 12c)/5.

Answer:

20°

Step-by-step explanation:

If it's an isosceles triangle, the two remaining angles should be equal. (Angles opposite to equal sides are equal)

∴ one remaining angle = (180° - 140°)/2

                                      = 40° / 2

                                      = 20°

Answer:

9 cups

Step-by-step explanation:

We can write a ratio to solve

5 cups                     x cups

------------            = ----------------

80 cookies            144 cookies

Using cross products

5 * 144 = 80x

720 = 80x

Divide by 80

720/80 = 80x/80

9=x

Answer:

7 1/5 cups of flour to mae 144 cookies

Step-by-step explanation:

80/5 = 20 cookies per cup of flour

so 20x7 = 140 and then you still need four more so take the four and another cup of flour and divide the 20 by 4 then you get 5 thus you 7 and 1/5ths cups

Answers:

one small box = 30 pounds

one large box = 40 pounds

==========================================================

Work Shown:

S+L = 70 since the two boxes combine to 70 pounds.

70S = weight of 70 small boxes

50L = weight of 50 large boxes

70S+50L = weight of 70 small and 50 large

70S+50L = 4100

The system of equations is

[tex]\begin{cases}S+L = 70\\70S+50L = 4100\end{cases}[/tex]

There are a few ways to solve this system. I'll use substitution.

I'm going to isolate L in the first equation like so

S+L = 70

L = 70-S

Which I'll then plug into the other equation to solve for S

70S+50L = 4100

70S+50(70-S) = 4100

70S+3500-50S = 4100

20S+3500 = 4100

20S = 4100-3500

20S = 600

S = 600/20

S = 30

Each small box is 30 pounds.

Use this value of S to find L

L = 70-S

L = 70-30

L = 40

Each large box is 40 pounds.

Like we expect, each large box weighs more compared to any given small box.

------------------

Check:

Both equations are true for the ordered pair (S,L) = (30,40). Therefore, the answers have been confirmed.

Step-by-step explanation:

The n-th term of an arithmetic sequence with first term a and common difference d is

a + (n - 1) d

So, the 51st term of A is

30 + 9 (51 - 1) = 480

while the 51st term of B is

30 + 4 (51 - 1) = 230

The difference between them 480 - 230 = 250.

Area of the rectangle is [tex]6u^{2}[/tex]

How to find area of rectangle if the vertices are given:

Let the vertices be or the given vertices:

A [0,-4]

B [-1,-3]

C [2,0]

D [3,-1]

Area of rectangle is twice the area of triangle, i.e. if the area of rectangle is ABCD and area of triangle is ABC.

Area of triangle is given by determinant:

Area of triangle = 1/2 [x1, y1]

                              1/2 [x2, y2]

                              1/2 [x3, y3]

                              1/2 [x4,y4]

Putting all the values in this format we  will get :

Area of triangle = 1/2 [0×-4]

                              [-1×-3]

                               [2×0]

Because we have assume 0 as x1 and -4 as y2

-1 as x2 and -3 as y2

2 as x3 and 0 as y3

By solving that equation we will get:

1/2[ −4 0 1]

[−3,1,1]

[0,−2,1]

=1/2(−4⋅(1⋅1+1⋅2)−0+1⋅(6−0))

=1/2|-6|= [tex]3u^{2}[/tex]

= -3=[tex]3u^{2}[/tex]

= [tex]6u^{2}[/tex]

In a two-dimensional plane, a triangle's area is the space it encloses. Known for having three sides and three vertices, a triangle is a closed shape. The sum of the spaces occupied by a triangle's three sides is known as its area. Half of the product of a triangle's base and height is the usual formula for calculating its area.The area that is included within the perimeter of a flat object or figure is generally considered to be the definition of the word "area." The square units used for measuring are square meters as the standard unit (m2). There are already established formulas for calculating the area of squares, rectangles, circles, triangles, etc.

Answer:

Hello!

Judging by the question you have provided I have come up with the correct solution:

y=25x+175

Step-by-step explanation:

The way I came up with the solution is by understanding how to write the correct equation using the correct variables in the correct places.

In the equation y=mx+b, the variable "b" will always be an independent variable.

The independent variable of Candace equation is "175 gallons". This is because this amount does not change throughout the entire equation.

Next, the variable "m" will always be a dependent variable.

The dependent variable of the Candace equation is "25 gallons". This is because this variable is effected by "x amount of hours".

So when you input these given variables in the correct places you get:

y=25x+175
