1. Take away the parentheses. x+2x+40+3x-50=15002

2. Add the X’s together.
x+2x+3x= 6x —> 6x+40-50=15002

3. Subtract 50 from 40.
40-50= -10 —> 6x-10=15002

4. Move -10 to the right hand side to make it positive.
6x=15002+10

5. Add 15002 and 10 together.
6x=15012

6. Divide 15012 by 6. Which makes the answer X=2502

Answer:

First, combine like terms by combining the variables and constants. Then use properties of equality to isolate the variable and find the value for x.

Answer:

36 dollars

Step-by-step explanation:

We need to think backwards to solve this question.

(8 - 2) x 2 = 12

(12 - 2) x 2 = 20

(20 - 2) x 2 = 36

A manufacturer produces bolts of a fabric with a fixed width. A quantity q of this fabric (measured in yards) that is sold is a

BigorU [14]

Answer:

$R'(20) = 2000$

Step-by-step explanation:

We are given the following in the question:

Quantity, q

Selling price in dollars per yard, p

$q=f(p)$

Total revenue earned =

$R(p)=pf(p)$

f(20)=13000

This means that 13000 yards of fabric is sold when the selling price is 20 dollars per yard.

f′(20)=−550

This means that increasing the selling price by 1 dollar per yards there is a decrease in fabric sales by 550.

We have to find R'(20)

Differentiating the above expression, we have,

$R'(p) = \displaystyle\frac{d(R(p))}{dp} = \frac{d(pf(p))}{dp} = f(p) + pf'(p)$

Putting the values, we get,

$R'(p) = f(p) + pf'(p)\\\\R'(20) = f(20) + 20(f'(20))\\\\R'(20) = 13000 + 20(-550) = 2000$

Answer:

B. $-\frac{7}{10}$ = -.7

Step-by-step explanation:

Replace all occurrences of − − with a single +. Two consecutive minus signs have the same mathematical meaning

$-.75+\frac{2}{5}+.4-\frac{3}{4}$

Find the common denominator.

$\frac{-.75*20}{20} +\frac{2*4}{20} +\frac{.4*20}{20}-\frac{3*5}{20}$

Simplify terms.

$\frac{-15+8+8-15}{20}$

Simplify the numerator.

$\frac{-14}{20}$

Reduce the expression by cancelling the common factors.

$-\frac{7}{10}$

<em>hope this helps, good luck :)</em>

Identify a sequence of transformations that maps triangle ABC onto triangle A"B"C" in the image below.

Murljashka [212]

Answer:

The correct option is B.

Step-by-step explanation:

It is given that triangle A"B"C" is the image of triangle ABC after transformation.

From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.

It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is

$(x,y)\rightarrow (-y,x)$

The corresponding sides of image A"B"C" are smaller than the preimage ABC.

$k=\frac{A"B"}{AB}=\frac{3}{6}=\frac{1}{2}$

Since k<0, therefore the transformation shows the reduction. The dilation rule is

$(x,y)\rightarrow (-\frac{1}{2}y,\frac{1}{2}x)$

$A(-3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(-3))\rightarrow (0,-1.5)$

$B(3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(3))\rightarrow (0,1.5)$

$C(0,5.2)\rightarrow (-\frac{1}{2}(5.2),\frac{1}{2}(0))\rightarrow (-2.6,0)$

Option B is correct.
