Simplify the expression 4(5+ -3x) +10​

Mathematics
1 answer:
BARSIC [14]3 years ago
7 0

Answer:

30 - 12x or 6(5 - 2x)

Step-by-step explanation:

Given expression:

  • 4[5 + (-3x)] + 10​

First, let us simplify the expression inside the parentheses;

  • ⇒ 4[5 + (-3x)] + 10​
  • ⇒ 4[5 - 3x] + 10​

Then, let us open the parentheses by simplifying the distributive property;

  • ⇒ 4[5 - 3x] + 10​
  • ⇒ 20 - 12x + 10​

Finally, let us simplify the expression by adding 10 to 20.

  • ⇒ 20 - 12x + 10​
  • ⇒ 30 - 12x

[Optional] Factor the expression by putting the expression in parentheses.

  • ⇒ 30 - 12x
  • ⇒ (30 - 12x)

Since 6 is divisible to all the terms in the expression, we can divide 6 to all the terms in the expression and take "6" outside the parentheses.

  • ⇒ 6(30/6 - 12x/6)
  • ⇒ 6(5 - 2x)

Therefore, the simplified expression is 30 - 12x or 6(5 - 2x).

Are exponential function one to one. How can you tell? What does this tell you about their inverses
aleksandrvk [35]

See in the explanation

<h2>Explanation:</h2>

<h3>1. Are exponential function one to one. How can you tell?</h3>
  • A function f is one-to-one if each value of x corresponds to exactly one value of y.

To demonstrate this, we take the Horizontal Line Test that states:

<em>A function f has an inverse function if and only if there is no any horizontal line that intersects the graph of f at more than one point.</em>

As you can see in the first figure, the horizontal line y=3 (the green one) intersects the graph of the exponential function y=e^x (the red one) in just one point. If you take every horizontal line y=y_{0} with y_{0} any real number, you will find that every line intersects the exponential function in just one point. Therefore, this function is one-to-one

<h3>2. What does this tell you about their inverses?</h3>

Another important thing is that:

  • A function has an inverse function if and only if is one-to-one.  

As we have demonstrated that exponential functions are one-to-one by Horizontal Line Test, then we conclude exponential functions have inverse functions. The domain of the inverse function is the range of the original one and the range of the inverse function is the domain of the original one. The inverse of y=e^x is y=ln(x) whose graph is the second figure below.

Ebuka's monthly rent is \$750$750dollar sign, 750. If Ebuka pays the rent late, his landlord charges 4\%4%4, percent interest pe
dem82 [27]

Answer: R(t) = 750 + 0.04t

Step-by-step explanation:

Here's the complete question:

Ebuka's monthly rent is $750. If Ebuka pays the rent late, his landlord charges 4% interest per week that the payment is late. Write a function that gives the total cost R(t), in dollars, of Ebuka's rent if he pays it t weeks late.

The above question will be represented by:

R(t) = $750 + (4% × t)

R(t) = 750 + (4/100 × t)

R(t) = 750 + 0.04t
