<span>0.35x – 4.8 < 5.2 – 0.9x
0.35x + 0.9x < 5.2 + 4.8
1.25x < 10
x < 10/1.25
x < 8

Solutions are all real numbers (-∞, 8)

Answer:

B) (–∞, 8)

Step-by-step explanation:

So the interval for the solution of a certain set is the numbers that can be used as value for X in the set and the set still be true, in order to solve this, you just need to solve the set by making it an equation:

0.35x – 4.8 < 5.2 – 0.9x

0.35x – 4.8 =5.2 – 0.9x

0.35x+0.9x=5.2+4.8

1.25x=10

x=8

So the maximum value of X will be 8, and when X is a negative value the set is true, so the interval would be all real numbers form -infinite to 8.

(-∞,8)

Answer:

  3/7

Step-by-step explanation:

The fraction is ...

  24\text{ g to }56\text{ g}=\dfrac{24\text{ g}}{56\text{ g}}=\dfrac{3}{7}\cdot\dfrac{8\text{ g}}{8\text{ g}}=\boxed{\dfrac{3}{7}}

Ymorist [56]

Answer:

First Question

lower limit of 9 mph  j =  8.5 \  mph

upper  limit of 9 mph q =  9.5 \  mph

Second Question

lower limit of 120 pounds is  i =  119.9 \  pounds

upper limit of 120 pounds is  l =  120.1 \  pounds

Third  Question

lower limit of 187 pounds is  a =  186.75 \  pounds

upper limit of 187 pounds is  b =  187.25 \  pounds  

Step-by-step explanation:

From the question we are told that

  The amount of beer administered is  three 12-ounce beers

  The  amount of coffee administered is  two cups of coffee

  The  speed limit is   60-mph

  The smallest unit of scale is  1 mph

  The first subject scores 9 mph

Generally given that the smallest unit of scale is  1 mph then the deviation of  9 mph will be by \frac{1}{2} \ mph

Hence the lower limit of 9 mph is

    j =  9 - 0.5

    j =  8.5 \  mph

And  the upper  limit of 9 mph is

    q =  9 + 0.5

    q =  9.5 \  mph    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by  \frac{1}{0.2} \ pounds

Hence the lower limit of 120 pounds is

    i =  120 - 0.1

    i =  119.9 \  pounds

And  the upper  limit of 120 pounds is

    l =  120 + 0.1

    l =  120.1 \  pounds    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then  187 pounds will deviate by  \frac{1}{0.5} \ pounds = 0.25 \ pounds

Hence the lower limit of 120 pounds is

    a =  187 - 0.25

    a =  186.75 \  pounds

And  the upper  limit of 120 pounds is

    b =  187 + 0.25

    b =  187.25 \  pounds

Which expressions are equivalent to 2 ln a 2 ln b - ln a? Check all that apply. Ln ab2 - ln a ln a 2 ln b ln a2 ln b2 - ln a 2 l
marysya [2.9K]

Equivalent expressions are expressions with same simplified form. Equivalent expressions for the given expression are;

  • Expression 2:  \ln(a) + 2\ln(b) = \ln(a) + \ln(b^2)  = \ln(ab^2)
  • Expression 3:  \ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)
  • Expression 5:  \ln(ab^2)

<h3>What are equivalent expressions?</h3>

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = log_a(c)

Some properties of logarithm are:

log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1\\\\ log_a(b) + log_b(c) = log_a(c)

Log with base e = 2.71828.... is written as \ln(x) simply.

The expression given is 2\ln(a) + 2\ln(b) - \ln(a)

We get its simplified form as

2\ln(a) + 2\ln(b) - \ln(a) = \ln(a) + \ln(b^2) = \ln(ab^2)

Simplifying given expressions:

  • Expression 1:  \ln(ab^2) - \ln(a) = \ln(ab^2/a)  = \ln(b^2)

This isn't same as simplified form of original

. Thus , this expression is not equivalent to the given expression.

  • Expression 2:  \ln(a) + 2\ln(b) = \ln(a) + \ln(b^2)  = \ln(ab^2)

This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.

  • Expression 3:  \ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)

This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.

  • Expression 4:  2\ln(ab) = \ln((ab)^2) = \ln(a^2b^2)

This isn't same as simplified form of original expression. Thus , this expression is not equivalent to the given expression.

  • Expression 5:  \ln(ab^2)

This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.

Thus, equivalent expressions for the given expression are;

  • Expression 2:  \ln(a) + 2\ln(b) = \ln(a) + \ln(b^2)  = \ln(ab^2)
  • Expression 3:  \ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)
  • Expression 5:  \ln(ab^2)
