Per hour? my best guess is 58 miles
All you have to do is divide 640 by 11

Answer:

The answer is 58.18 $\frac{miles}{hours}$

Step-by-step explanation:

When we have to determine the speed of an object, we need two informations: total distance and total time of travel that distance. The speed is just an average of distance and time, that is:

$speed=\frac{distance}{time}$

So, we have:

distance=640 miles

time= 11 hours

$speed=\frac{640}{11}=58.18\frac{miles}{hours}$

Finally, the average rate of the car is $58.18\frac{miles}{hours}$

Solve the following system of equations and show all work.<br> y = 2x^2 +9x<br> y = 4x + 25

Genrish500 [490]

Answer:

x = 5/2 thì y = 35 và x = -5 thì y = 5

Step-by-step explanation:

thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:

4x + 25 = 2x ^ 2 + 9x

⇒2x ^ 2 + 5x - 25 = 0

⇒ x = 5/2 và x = -5

thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35

thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5

The commission for selling a house is$11825, which is 5.5% of the selling price. What is the selling price of the house?

Rzqust [24]

In this case, the best method starts with finding one percent of the selling price. To do this, divide the commission ($11825) by 5.5. This gets you 1%, which is $2150. Next, multiply this number by 100, turning 1% into 100%. Your final answer is $215,000.

Simplify the Expression<br> - 1/2 (8b+3)+3b=

Anna35 [415]

Answer:

-b -3/2

Step-by-step explanation:

-1/2(8b+3) + 3B (a negative times a positive equals a negative)

1. Mutiply -1/2 by 8b and then by 3

(-1/2 x 8b -1/2 x 3) + 3b

-4b - 3/2 + 3b

2. Add -4b + 3b = -b

What I the equation in standard form of the line that passes through the points(4,-8) and has a slope of 1/4

valentinak56 [21]

Answer:

Standard form of the line with point (4,-8) and slope of 1/4 is

-x + 4 y = -36.

Step-by-step explanation:

The slope of the line equation = 1/4

The point is given as (4,-8).

Now, by POINT SLOPE formula,

The line equation with slope m nad point (x0,y0) is given as:

(y - y0) = m (x -x0)

So, the line equation here is given as

$y -(-8) = \frac{1}{4} (x -4)\\\implies 4(y + 8) = x - 4\\4 y + 32 = x - 4\\4y = x - 36$

Now, the standard form of line equation is Ax + By = C

Here, 4y = x - 36 ⇒ 4y - x = -36

or, -x + 4y = -36 is the standard form.

Hence,standard form of the line with point (4,-8) and slope of 1/4

is -x + 4y = -36.
