Compare and contrast equation notation and function notation

Sonbull [250]

An equation is a relationship whose primary use is solving for a value.
An equation makes use of the equality (=) sign.
An example of an equation is x + 6 = 46.

A function is a mathematical machine whose purpose is to transform input variables into output according to the function rule.
A function can be described by an equation, a graph, a program, a table, etc.
An example of a function is y = 2x - 5.

Consider this equation: 9x - 7 - 3x + 9 = x + 7 + 5x + 9. How many solutions does this equation have?

garri49 [273]

Final Answer: No Solution. The equation would have 0 solutions.

Steps/Explanations:

Hey there! The answer is No Solution because -7 = 7. If 7 = 7, then it would be true and have one solution, which is not the case here.

Step 1: You should cancel $9$ on both sides.

$9x - 7 - 3x = x + 7 + 5x$

Step 2: Simplify $9x - 7 - 3x$ to $6x - 7$ .

$6x - 7 = x + 7 + 5x$

Step 3: Simplify $x + 7 + 5x$ to $6x + 7$ .

$6x - 7 = 6x + 7$

Step 4: You'll need to cancel $6x$ on both sides.

$- 7 = 7$

Step 5: Since $-7 = 7$ is false, there would be no solution.

No Solution

Calculate the value of (6.72 10^5)+ (3.2 x 10^4) Give your answer in standard form.

dangina [55]

Answer:

$7.04\cdot 10^{5}$ or 704,000

Step-by-step explanation:

Standard Form of Numbers

Any number that we can write as a decimal number between 1.0 and 10.0, multiplied by a power of 10, is said to be in Scientific Notation. Some authors consider standard form and scientific form as the same, but others state that standard form is the common form of expressing numbers, i.e., a sequence of digits, separated by thousands by a comma, and separated from the decimal part by a dot.

We'll give here both answers.

We have to calculate:

$6.72\cdot 10^{5}+3.2\cdot 10^{4}$
