<em>If it is one platter per person, the following will be true,</em>

Answer:

c = 7p

Step-by-step explanation:

This is because every time someone buys a platter, it adds $7 to the total cost

-> If two people buy a platter, it is 7 + 7, aka 7 *2

-> If three, it is 7 + 7 + 7 aka 7 * 3

Using this pattern, we can see that the total cost will be 7 times the number of people there.

We can put this into an equation by doing:

c = 7p

<h3>Answer: c = 7p</h3>

Explanation:

Let's say 5 people get a lunch platter. The cost would be 7*5 = 35 dollars.

Or if 3 people got the lunch platter, then it would be 7*3 = 21 dollars

In general, the cost is 7p dollars where p is a placeholder for a whole number. So that's how we end up with c = 7p

Ada, Betty, Chris and David have $45 in total Ada gota 52 fromBetty, Chris tripleshis money and Davids money is cut by hall four

andrezito [222]

Using a system of equations, it is found that initially Ada has $0.385.

For the system, we have that the variables are:

x is Ada's amount.
y is Betty's amount.
z is Chris's amount.
w is David's amount.

$45 total, hence:

$x + y + z + w = 45$

Ada <u>gets 2 from Betty</u>, hence:

$x + 2 = y - 2$

$x = y - 4$

$y = x + 4$

<u>Chris triples</u> his money and <u>David's</u> money is <u>cut by half</u> four of them have the same amount, hence:

$x + 4 = y = 3z = \frac{w}{2}$

Then:

$3z = x + 4$

$z = \frac{x + 4}{3}$

$x + 4 = \frac{w}{2}$

$w = 2x + 8$

Solving for w, we find Ada's initial amount.

$x + y + z + w = 45$

$x + x + 4 + \frac{x + 4}{3} + 2x + 8 = 45$

$4x + 12 + \frac{x + 4}{3} = 45$

$12x + 36 + x + 4 = 45$

$13x = 5$

$x = \frac{5}{13}$

$x = 0.385$

Initially, Ada has $0.385.

Which is a zero of the function f(x)=3x−12?

N76 [4]

<h3>Answer: x = 4</h3>

==================================================

Explanation:

Replace f(x) with 0 and solve for x.

f(x) = 3x-12

0 = 3x-12

3x-12 = 0

3x = 12

x = 12/3

x = 4 is a zero, aka root, of the function

---------------

Check:

f(x) = 3x-12

f(4) = 3(4)-12

f(4) = 12-12

f(4) = 0

The answer is confirmed.
