Answer:

B) n + 16

Step-by-step explanation:

We are given the expression 9 + 7 + n.

Here we need to simplify.

Simplify means we need to simplify the like terms.

Let's see what a like term is.

If we have the same variable with the same exponent, then they are called like terms.

The constants are the like terms, we can simplify them.

Examples:

2xy, -3xy are the like terms

$5xy^2, -8xy^2$ are like terms

4, 5, -7, 8 are the like terms.

In the given expression 9 + 7 + n

The like terms are 9 and 7. There are in the operation of addition. So we can add them.

So, 9 + 7 + n

= 16 + n

This can be written as n + 16 by commutative property of addition.

Therefore, the answer is B) n + 16

This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.

The x-coordinate of the point(s) of intersection is the solution.

_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)

Pls help me that would be great

omeli [17]

No. No. It is not linear because the slope has to be able to be plugged in to any x, y coordinates and be placed on the line.

Teboho has to sell a certain number of cars each month. For every car he sells over and above this number he earns 17% commissio

Nastasia [14]

The commission earned are R41123.17, R47931.67 and R15024.09

<h3>The prices of the cars before VAT was added</h3>

The VAT included prices are given as:

R271 800,00; R316 800,00 and R99 300,00.

The VAT rate is 12.36%.

So, the price before VAT is calculated as:

VAT included = Price without VAT * (1 + 12.36%)

This gives

VAT included = Price without VAT * 1.1236

So, we have:

Price without VAT = VAT included/1.1236

For the three cars, we have:

Price without VAT = R271 800.00/1.1236 = R241901

Price without VAT = R316800.00 /1.1236 = R281951

Price without VAT = R99300.00/1.1236 = R88377

Hence, the prices of the cars before VAT was added are R241901, R281951 and R88377

<h3>The commission he earned on the cars.</h3>

This is calculated as:

Commission = Price * 17%

So, we have:

Commission = R241901 * 17% = R41123.17

Commission = R281951 * 17% = R47931.67

Commission = R88377 * 17% = R15024.09

Hence, the commission earned are R41123.17, R47931.67 and R15024.09
