Neil drives at an average speed of 60 miles/hour to reach
nikklg [1K]

Answer:

 480/(x+60) ≤ 7

Step-by-step explanation:

We can use the relations ...

 time = distance/speed

 distance = speed×time

 speed = distance/time

to write the required inequality any of several ways.

Since the problem is posed in terms of time (7 hours) and an increase in speed (x), we can write the time inequality as ...

 480/(60+x) ≤ 7

Multiplying this by the denominator gives us a distance inequality:

 7(60+x) ≥ 480 . . . . . . at his desired speed, Neil will go no less than 480 miles in 7 hours

Or, we can write an inequality for the increase in speed directly:

 480/7 -60 ≤ x . . . . . . x is at least the difference between the speed of 480 miles in 7 hours and the speed of 60 miles per hour

___

Any of the above inequalities will give the desired value of x.

- Lulah is buying beach balls for her beach
Elan Coil [88]

The set of the ordered pairs is a {(1, 6), (2, 12), (3, 18), (4, 24)}.

According to the statement

We have to find that the set of the ordered pairs.

So, For this purpose, we know that the

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate.

From the given information:

The package contains 6 beach balls And

the number of packages x for a total of 1, 2, 3, and 4 packages.

Then

(packages, balls) = (1, 6)

Multiplying by 2, 3, and 4, we find the set of ordered pairs to be ...

{(1, 6), (2, 12), (3, 18), (4, 24)}

So, The set of the ordered pairs is a {(1, 6), (2, 12), (3, 18), (4, 24)}.

Write the equation of a line in slope intercept form that has a slope of 1/5 and contains (-10,6)
VLD [36.1K]

Answer:

y = \frac{1}{5} x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = \frac{1}{5}, hence

y = \frac{1}{5} x + c ← is the partial equation

To find c substitute (- 10, 6) into the partial equation

6 = - 2 + c ⇒ c = 6 + 2 = 8

y = \frac{1}{5} x + 8

Solve the system of equations. (3x + 4y = 5) (2x - 3y = -8)
vovikov84 [41]

Answer:

the solution is (-1, 2)

Step-by-step explanation:

Let's solve the system

(3x + 4y = 5)

(2x - 3y = -8)

using the method of elimination by addition and subtraction.  Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:

  9x + 12y = 15

  8x - 12y  = -32

-----------------------

 17x       = - 17, so x = -1.  

Replacing x in the second equation by -1, we get:

2(-1) - 3y = -8, or

2 + 3y = 8,

or 3y = 6.  Thus, y = 2, and the solution is (-1, 2).
