I have no idea how to do this one please help

Answer:

Step-by-step explanation:

1. change in y over change in x.

  [tex]\frac{100-98.6}{0-5}[/tex] = [tex]\frac{1.4}{-5}[/tex]

  This becomes your slope.

   the y-intercept is 100 because at x = 0, y= 100.

   So plug these values into y = mx + b and you get y = [tex]\frac{1.4}{-5}[/tex]x + 100.

2. If the line starts at x = 0, then if you want to get a value for 2 minutes prior           you have to use -2 because 0 - 2 = -2.

   y = [tex]\frac{1.4}{-5}[/tex](-2) + 100

   Set it equal to zero and solve algebraically. The answer should be   100.56.

3. If we want to see how many minutes it takes to get to an altitude of 0, we have to make y = 0  and solve for x. This is because we know that y will be 0 but we don't know how long it takes.

    0 = [tex]\frac{1.4}{-5}[/tex]x + 100

    Solve algebraically and you should get an answer around 357.

Answer:

58.2

Step-by-step explanation:

48.5*1.2=58.2

Im gonna answer this in calculator form. It might be non-calculator but if y = 20.07 when x = 9, than u can divide 9 by 9 to get 1. 1 x 14 = 14. Now vise versa. 20.07 / 9 = 2.23. 2.23 x 14 = 31.22

= 31.22.

Thanks please heart because im depressed. bye

Answer:

As the product of the slop of both lines is -1.

Therefore, the given equations are perpendicular.

Step-by-step explanation:

Given the equations

[tex]-3x+y=-4[/tex]

[tex]x+3y=6[/tex]

The slope-intercept form of the equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

Writing both equations in the slope-intercept form

[tex]-3x+y=-4[/tex]

[tex]y=3x-4[/tex]

So by comparing with the slope-intercept form we can observe that

slope of equation = 3

i.e.

[tex]m_1=3[/tex]

also

[tex]x + 3y = 6[/tex]

[tex]3y\:=\:6-x[/tex]

[tex]y=-\frac{1}{3}x+2[/tex]

So by comparing with the slope-intercept form we can observe that

the slope of equation = -1/3

i.e.

[tex]m_2=-\frac{1}{3}[/tex]

as

The slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

so

The slope [tex]m_2[/tex] is the negative reciprocal of the slope [tex]\:m_1[/tex]

Also, the product of two perpendicular lines is -1.

i.e.

[tex]m_1\times m_2=-1[/tex]

VERIFICATION:

It is clear that the product of the slop of both lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]3\times \frac{-1}{3}=-1[/tex]

Therefore, the given equations are perpendicular.

Answer:

12/3=4

Step-by-step explanation:

it's 4, 2/3's stay the same. do the reciprocal on 1/6 which will be 6/1 and multiply

2/3(6/1)=12/3

and turn it to a mixed fractions and you would get 4

Answer:

A. -5

Step-by-step explanation:

Step-by-step explanation:

It is given that,

The bakers at Healthy Bakery can make 350 bagels in 5 hours.

We need to find how many bagels can they bake in 20 hours.

In 5 hour = 350 bagel

In 1 hour = 70 bagel

To find no of bagel in 20 hours, multiply 20 by 70 as follows :

In 20 hours = 70×20

= 1400 bagels

So, 1400 bagels can they bake in 20 hours. Also, the rate per hour is 70 bagel/hour.

Step-by-step explanation:

Answer:

C. 0.68

Step-by-step explanation:

Given;

number of products sold in a day by toll-free sales line = 85 products

number of calls in a day = 125

The daily success rate of the sales line is given by the ratio of the total products in a day to total number of calls in a day.

The daily success rate of the sales line = total products sold / number of calls

The daily success rate of the sales line = 85 / 125

The daily success rate of the sales line = 0.68

Therefore, the daily success rate of the sales line is 0.68

Answer:

12 is 20% of 60

28 is 35% of 80

84 is 42% of 200

32 is 80% of 40

35% of 60 is 21

25% of 132 is 33

5% of 40 is 2

15% of 20 is 3

Step-by-step explanation:

For the first 4 situations, you need to multiply the first number by the reciprocal of the percentage as a fraction, which would be 100/(percent). Here's an example:

12 is 20% of x

x = 12*(100/20)

100/20 was used because that is the reciprocal of 20/100, which is 20% as a fraction out of 100.

For the last 4 situations, you just need to multiply the number by the percentage as a decimal. For example:

35% of 60 is x

x = 60*.35

Domain and range:

The domain of a function is all the values the the input assumes.

The range of a function is given by all the values that the output assumes.

In a graphic:

The domain is given by the x-values, the horizontal axis.

The range is given by the y-values, the vertical axis.

In this question:

x, in the horizontal axis, assumes values between -4 and 2.

The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.

Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.

For more about domain and range of functions, you can check: https://brainly.com/question/21853810?referrer=searchResults

D. [tex]-4 \le x \le 2[/tex]

The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.

By visual examination of the function, we conclude that domain of the function is represented by:

[tex]Dom\{f(x)\} = [-4, 2][/tex]

Which is equivalent to the following expression in Inequality notation:

[tex]-4 \le x \le 2[/tex]

Therefore, we conclude that right answer is D.
