Answer:

Simplified : 3x - 15

Step-by-step explanation:

5 - 2(-4x + 10) - 5x

5 + 8x - 20 - 5x

5 + 3x - 20

3x - 15

Help please i dont know this thank you<33
jok3333 [9.3K]

Answer:

  • 42
  • 35
  • 16

Step-by-step explanation:

Put the value where the variable is and do the arithmetic. It can save some steps to simplify the expression first.

  35 -c³ +8 = 43 -c³

<u>c = 1</u>

  43 - 1³ = 43 -1 = 42

<u>c = 2</u>

  43 - 2³ = 43 -8 = 35

<u>c = 3</u>

  43 -3³ = 43 -27 = 16

The values that go in the blanks are 42, 35, 16.

<em>Additional comment</em>

It does not take long to learn how to use a spreadsheet for evaluating the same formula with a number of different values of the variable(s). Graphing calculators can do this, too. It is always appropriate to use the right tool for the job.

Familiarity with multiplication and addition facts is a very good place to start. It is also useful to memorize the squares and cubes of small integers. The latter are needed here.

What are the Slope and the Equation of the Image?
Rama09 [41]

change in y/change in x

y2-y1/x2-x1

-1--5/0-2

-1+5/-2

4/-2

-2

slope is -2

now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair

y = -2x +b

-1 = -2(0)+b

-1 = b

the equation is

<h2>y = -2x - 1</h2>

I need help please!! Please do not add an answer just for points, thank you!!
Sholpan [36]

let us assume that the first company the cab flat rate is 5$ and the cap driver charges 2$ per mile .for the second company the cab flat rate is 3$ and the cab driver charges 3$ per mile.

a. the company charges per ride at least 5$ and an extra 2$ per mile

b.the equation we will choose is slope intercept since we know the

y-intercept which is the cab flat rate .

y=mx+b

where

m :is the slope

b:is the y-intercept

y:total amount

x. is the milage

total amount=2x+5.

c.the slope will be 2$ which is the change in amount per mile.the y-intercept will be the cab's flat rate.

27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.
ololo11 [35]

The polar equation will be  r=\dfrac{4}{1+cos\theta}

<h3> What is the polar equation?</h3>

A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.

From the equation, we are told that

The  Eccentricity: e = 1

The  Directrix is   y = 4

Generally, the polar equation for e =  1  and y  =  + c is mathematically represented as

r =\dfrac{e\times c}{1+ecos\theta}

r =\dfrac{1\times 4}{1+1\times cos\theta}  

 r=\dfrac{4}{1+cos\theta}

 

Therefore the polar equation will be  r=\dfrac{4}{1+cos\theta}

To know more about the polar equation follow
