Step-by-step explanation:

The art museum charges a one-time fee of $8.25 plus $2.25 per month.

So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)

Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.

Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)

So, from both the equations it is clear that for only joining the monthly charges are zero.

So, f(0) = 8.25 and g(0) = 10.75.

Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)

Answer:

y = x - 40

Step-by-step explanation:

Points on the graph: (0, -40) and (60,20)

Slope:

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

m=(20+40)/(60-0)

m=60/60

m = 1

Slope-Intercept

y - y1 = m(x - x1)

y + 40 = 1(x -0)

y + 40 = x

y = x - 40

Answer:

y=-x-40

Slope intercept form is y=mx+b

slope=rise/run

slope= -40/40 = -1

y-y1=m(x-x1)

y-(-40)= -1(x-0)

y+40=-x+0

y=-x+0-40

y=-x-40

hope that helps?

Step-by-step explanation:

tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)

                      = (sin2B + cos2B)/[(cosB)(sinB)]

                       = 1/[(cosB)(sinB)]

                        = (1/cosB)(1/sinB)

                        = (secB)(cscB)

Answer:

Therefore the area of the kitchen counter is 21 square feet

Step-by-step explanation:

Area of the sink = 2 x 3

= 6 square ft.

Area of the kitchen counter = 9 x 3 -(6)

=27 - 6

= 21 square ft.

The area of the kitchen counter is 21 square ft.

Answer:

Therefore the area of the kitchen counter is 21 square feet

Step-by-step explanation:

Area of the sink = 2 x 3

= 6 square ft.

Area of the kitchen counter = 9 x 3 -(6)

=27 - 6

= 21 square ft.

The area of the kitchen counter is 21 square ft.

Answer:

$32

Step-by-step explanation:

200 + 57 = 257.

385 - 257 = 128

128 x 3/4 = 96 (deposited)

128 - 96 = 32

Answer:

Step-by-step explanation:

x                y               Difference (d)

-1              -1                       -

0             -0.5             -0.5 - (-1) = 0.5

1                 0               0 - (-0.5) = 0.5

2              0.5              0.5 - 0 = 0.5

3                1                 1 - 0.5 = 0.5

There is a common difference (d) = 0.5

Therefore, table represents a linear function.

Let the equation of the linear function is,

y = mx + b

Here, m = Slope and b = y-intercept

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] will be,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Two points from the given table are (-1, -1) and (0, -0.5)

m = [tex]\frac{-0.5-(-1)}{0-(-1)}[/tex]

m = 0.5

Y-intercept of the line 'b' = -0.5 (Value of y at x = 0)

Therefore, equation of the line will be,

y = 0.5x - 0.5

Answer:

7x²-3x

Step-by-step explanation:

What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.

Area of a square = Length * Length

Area of the inner square = x (x+7)

Area of the inner square = x²+7x

Area of the outer square = 4x(2x+1)

Area of the outer square = 8x²+4x

Area of the shaded region = Area of outer square - Area of inner square

Area of the shaded region = (8x²+4x)-(x²+7x)

Area of the shaded region = 8x²+4x-x²-7x

Area of the shaded region = 7x²-3x

This gives the area of the shaded region

Answer:

35 for perimeter of b

122.5 for perimeter of a

Step-by-step explanation:

To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.

Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply

7*35 = 2x

x = 122.5 :)

Answer:

The perimeter is 35.

Step-by-step explanation:

To find perimeter, add all the sides together.

9 + 9 + 5 + 12 = 35

The perimeter is 35.

Step-by-step explanation:

convert 1.25 meters to feet

1 meter = 3 feet

1.25 meters = 1.25 x 3 = 3.75 feet
