The function y=12x when plotted using the interval of
x-values from -1 to 3 will give a straight line on a given plot. Therefore the
function rule of a line y=mx+b can be used to describe the growth or
progression of this function. The rule states that y is directly proportional
to x.
The solution to (21x) - (-16 + 7x) is 14x + 16
<h3><u>Solution:</u></h3>
Given that (21x) - (-16 + 7x)
We have to evaluate the given expression
Let's look at the given expression
(21x) - (-16 + 7x)
Multiply the terms within second bracket with minus sign
<em><u>There are two simple rules to remember:</u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive
⇒ (21x) + 16 - 7x
Removing the parenthesis
⇒ 21x + 16 - 7x
Combining the like terms,
⇒ 14x + 16
Thus the solution is 14x + 16
Ok i will try to answer but i really dont have that much of a clue right now
If I am correct the answer is 369,600 feet per hour.
