Answer:

Option B is the correct answer.

Step-by-step explanation:

The cost in dollars, c, of renting a carpet cleaner is given by the linear equation. C = 20+25x, where x is the number of days.

Here we need to find cost of carpet cleaner for 11 days.

That is x = 11 days

Substituting in C = 20+25x

                       C = 20+25 x 11 = 20 + 275 = 295 $

Cost for renting the unit for 11 days = 295 $

Option B is the correct answer.

Answer:

(a) A(x)=160x-2x^{2}

(b) x=40\textrm{ m}

(c) Maximum area=3200 square meters

Step-by-step explanation:

(a)

Given:

Total length for fencing = 160 m

Width of the rectangle = x m.

Let the other length of the rectangle be y m.

Then, from the figure,

x+y+x=160\\2x+y=160\\y=160-2x

Now, area of a rectangle is equal to the product of its length and width.

So, area is, A(x)=xy=x(160-2x)=160x-2x^{2}

(b)

Given:

A(x)=160x-2x^{2}

For maximum area, derivative of area with respect to x must be 0.

So, \frac{dA}{dx}=0\\\frac{d}{dx}(160x-2x^{2})=0\\160-4x=0\\4x=160\\x=\frac{160}{4}=40\textrm{ m}

Therefore, for maximum area, x=40\textrm{ m}.

(c)

Given:

A(x)=160x-2x^{2}

Maximum area occurs at x=40. Plug in 40 for x in A(x) expression. This gives,

Maximum area is,

A(x=40)=160(40)-2(40)^{2}\\A(x=40)=6400-2\times 1600\\A(x=40)=6400-3200=3200\textrm{ }m^{2}

Therefore, maximum area is 3200 square meters.

Write an algebraic rule to describe the translation C(5, –4) C’(–2, 1)
sdas [7]
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)

Mumz [18]

Question is incomplete, here is the complete question below:

Three students were given the expression shown and were asked to take a common factor out of two of the terms.

Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent.

7-8x+22

Calvin: 7−2(4x+11)

Calvin's expression is (correct/incorrect) because .............

Greg: 7+14x

Greg's expression is (correct/incorrect) because ............

Ruben: 7+2(4x+11)

Ruben's expression is (correct/incorrect) because .

Equivalent Expression

The correct simplification of this expression is ...............

Answer:

The correct simplification of this expression is 7-2(4x-11)

Step-by-step explanation:

Calvin: 7−2(4x+11)

Calvin's expression is incorrect because if -2 is taken as common term then sign (+) should also be changed to (-)

i.e. 7−2(4x+11)  produces 7-8x-22 which is not equivalent to 7-8x+22

Greg: 7+14x

Greg's expression is incorrect because  7+14x  is not equivalent to 7-8x+22

Ruben: 7+2(4x+11)

Ruben's expression is incorrect because  7+2(4x+11) =7+8x+22 which is not equivalent to 7-8x+22

Equivalent Expression  is 7-2(4x-11)

The correct simplification of this expression is 7-2(4x-11)
