First you need to combine like terms
7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
x=-3/4

A credit card company applies a 6% fee on all transactions under $10. You purchased coffee for $4.80. What fee amount will be ap
Romashka [77]

Answer:

$5.08

Step-by-step explanation:

Step one:

given data

We are told that a credit card company applies a 6% fee on all transactions under $10

since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable

so

=6% of 4.80

=6/100*4.80

=0.06*4.8

=$0.288

Step two:

the total fee will be

=0.288+4.80

= $5.08

What is the difference?
slega [8]

Answer:

<h3>The answer is option D.</h3>

Step-by-step explanation:

First we must first find the LCM

The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is

x² + 3x + 2

So we have

\frac{x}{ {x}^{2} + 3x + 2 }  -  \frac{1}{(x + 2)(x + 1)}  \\  \\  =  \frac{x - 1}{ {x}^{2} + 3x + 2 }

Hope this helps you

For the function f(x) = -4x - 5, what are the outputs for the inputs -4, 1, 3, and 11?
Anika [276]

We have to find the output values for the given input values of the function given as,

  • f(x) = -4x - 5

Here, x = Input value of the function

And f(x) = Output values

By substituting the input values of x as,

For x = -4,

f(-4) = -4(-4) - 5

      = 16 - 5

      = 11

For x = 1,

f(1) = -4(1) - 5

    = -4 - 5

    = -9

For x = 3,

f(4) = -4(3) - 5

     = -17

For x = 11,

f(11) = -4(11) - 5

     = -44 - 5

     = -49

       Therefore, Option (A) will represent the output values for the given input values.
