Answer:

The function f(x) = 275-55x represents the amount of money Bradley still owes.

Step-by-step explanation:

Given that:

Amount Bradley owes = $275

Amount Bradley pays each week = $55

Let,

x be the number of weeks.

We will subtract the amount paid every weeks from the total amount, where x is the number of weeks. The function will be given by;

f(x) = 275 - 55x

Hence,

The function f(x) = 275-55x represents the amount of money Bradley still owes.

In exercises 8-10, write a system of linear equations that has the ordered pair as its solution. (-6, -2)

Anika [276]

Answer:

(8) $x + y = -8$ and $2x - y = -10$

(9) $3x - y = -54$ and $4x + y = -30$

(10) $x + y = 2$ and $x - y = 2$

Step-by-step explanation:

Given [Missing from the question]

$(8).\ (-6,-2)\ \\ (9).\ (-12,18)\ \\ (10).\ (2,0)$

Required

Write a system of linear equations

The solutions to this question is open and have different solutions

Solving (8) (-6,-2)

Let the equations be: x + y and 2x - y

$x + y = -6 - 2$

$x + y = -8$ --- (1)

$2x - y = 2 * (-6) - (-2)$

$2x - y = -10$ -- (2)

So, the equations are:

$x + y = -8$ and $2x - y = -10$

Solving (9) (-12, 18)

Let the equations be: 3x - y and 4x + y

$3x - y = 3 *(-12) - 18$

$3x - y = -54$

$4x + y = 4 * (-12) + 18$

$4x + y = -30$

So, the equations are:

$3x - y = -54$ and $4x + y = -30$

Solving (9): (2,0)

Let the equations be: x + y and x - y

$x + y = 2 + 0$

$x + y = 2$

$x - y = 2 - 0$

$x - y = 2$

So, the equations are:

$x + y = 2$ and $x - y = 2$

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than

Ludmilka [50]

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111 Eqn 1

y = 2x + 3 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

$\frac{3x}{3}=\frac{108}{3}\\x = 36$

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75

What's greater?<br> -8 or -1/20

ankoles [38]

You can say : -1/20 = -0.05 so -8<-0.05 so -1/20 is greater because its negative :))
