Answer:  134 miles

Step-by-step explanation:  

f(m) = 16.95 + 0.92m

140.23 = 16.95 + 0.92m

0.92m = 140.23 - 16.95

0.92m = 123.28

m = 123.28/0.92

m = 134 miles

Answer:

-3(4c-2) -2c = -14c+6

Step-by-step explanation:

We need to find the equivalent expression for -3(4c-2) -2c.

First we open the brackets as follows :

-3(4c-2) -2c

= -12c+6-2c

=-12c-2c+6

=-14c+6

So, the equivalent expression is -14c+6.

Answer:

2) B) 1/4(n-64)

Step-by-step explanation:

Answer:The distance from a point to a line is

distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)

So first convert the formula for the line to standard form

5x+2y=4

5x+2y-4=0

a=5, b=2, c=-4, x0=15, y0=-21

Answer:

small cups=30

large cups=40

Step-by-step explanation:

let x be the number of small cups and y the number of large cups.

-Given that 10 more cups than small cups of lemonade were sold:

#Before the 10 more were sold, the number of x and y sold were equal>

The number of small cups sold was 30

Answer:

-5/4

Step-by-step explanation:

The slop is rise over run

which means we need to find the rise over run of this equation:

So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)

So, you go down 5 times which means the top of the slope is -5

Now, how many times do we need to run to get the next plot?

You need to run 4 times to the right to get the next point now we have all the things to solve the problem:

Slope=rise/run

Answer: -5/4

Answer:

A. -1

Step-by-sep explanation:

If PQ is perpendicular to RS, therefore, the slope of RS would be the negative reciprocal of PQ.

Slope of PQ:

P(6,-2), Q(-2, 8)

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 -(-2)}{-2 - 6} = \frac{10}{-8} = -\frac{5}{4} [/tex]

Slope of RS:

Slope of RS is the reciprocal of the slope of PQ, since they are perpendicular.

⅘ is the reciprocal of -⁵/4. Therefore, the slope of RS = ⅘.

Use the slope formula to find the value of y in R(-4, 3), S(-9, y).

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

Plug in the value

[tex] \frac{4}{5} = \frac{y - 3}{-9 -(-4)} [/tex]

[tex] \frac{4}{5} = \frac{y - 3}{-5} [/tex]

Cross multiply

[tex] (4)(-5) = (y - 3)(5) [/tex]

[tex] -20 = 5y - 15 [/tex]

Add 15 to both sides

[tex] -20 + 15 = 5y - 15 + 15 [/tex]

[tex] -5 = 5y [/tex]

Divide both sides by 5

[tex] \frac{-5}{5} = \frac{5y}{5} [/tex]

[tex] -1 = y [/tex]

y = -1

Answer:

The answer is undefined

Step-by-step explanation:

The slope of the line that passes through points (2, -3) and (2, 13) is not defined.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through points (2, -3) and (2, 13)

The slope 'm' of any straight line is given by:

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

Plug the values to find the slope of the line:

m = (13 + 3)/(2-2) = 16/0 = not defined

Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.

Answer:

A contingency table

Step-by-step explanation:

Hypothesis tests carried out on contingency tables are based on the chi-square, a statistic.

The contingency table is a Frequency tables of two variables presented at the same time. These tables are constructed when we represent all the levels of a variable as rows in a table and represent the other variables as columns, after which we find the joint or cell frequency for every of the cell.

Answer:

4.7 seconds per word

Step-by-step explanation:

11/2.34=4.7

(Im only guessing)

The average speed of Kim is 4.2857 pages per hour.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

It took Kim 2 hours 34 minutes to type an 11 page

1 hour = 60 minutes

1 minute = 1/60 hour

34 minutes = 34/60 hour = 0.567 hour

Total hour = 2.567

Now,

Average speed = Number of pages / Number of hour

Average speed = 11/2.567

Average speed = 4.2857 pages per hour.

Hence "The average speed of Kim is 4.2857 pages per hour".

Answer:

Hopefully this makes sense, but x=+1 and y=-4

Step-by-step explanation:

Lets start with Y. how do you go from 7 to 3? you subtract 4. then, how do you go from 3 to -1? Well... lets subtract till we get to -1. That would be -4. Can you do that for the rest? if so, your answer is -4 for y. for x it just adds a number each time.

Answer:

There are 2 dogs

Explaination:

If there are 28 eyes in total,

Dogs- 4 eyes

Chickens- 8 eyes

Fishes - 16 eyes

In total they have 28 eyes

if there are 16 legs,

Dogs- 8 legs

Chickens- 8 legs

Fishes- 0 legs

So,

2 Dogs

4 Chickens

8 Fishes

( the problem even said that there are twice as many fish as chickens)

Answer:

  (3, 0)

Step-by-step explanation:

The line through these points intersects the x-axis at x=3.

The x-intercept is (3, 0).

_____

The x-intercept can be computed from ...

  x-intercept = x1 -y1(x2 -x1)/(y2 -y1)

  = -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6

  x-intercept = 3

__

Here, it is simple enough to plot the points and see where the line crosses the x-axis.

Answer:

x+b+2 * c - d

I believe that's the expression

Step-by-step explanation:

x+b+2c - d is account balance after the transaction as an algebraic expression.

An expression is combination of variables, numbers and operators.

Given,

Lizzy has a total of x dollars in her checking account

She makes a deposit of b dollars cash and two checks each worth c dollars.

She would like d dollars in cash from this transaction. She has enough to cover the cash received in her account.

This can be expressed by algebraic expression as below.

x+b+2c - d

Hence x+b+2c - d is account balance after the transaction as an algebraic expression.
