A: 7! and
<span>B: 5040
you only have 7 slots with 7 * 6 * 5 * 4 * 3 * 2 * 1</span>
Step-by-step explanation:
There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.
Now, let us consider some interesting expression

If the value of x = 2, then the expression will be equal to 13.
i.e.
∵ when x = 2
Considering a word problem
<em>'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?</em>
Let 'x' be the number of oranges Tom has.
The number of oranges Tony has = x + 3
as Tom has 10 oranges, so x = 10
Therefore, the number of oranges Tony has = x + 3
= 10 + 3 = 13
Therefore, the number of oranges Tony has = 13
The vertex (5,39)
5 is the value of x. 39 is the value of y. y is the cost function of the minimum value in dollars.
(5,39) vertex means that <span>Buying five of each type of plant costs $39, which is the lowest possible cost.</span>
The answer is (-2,-10) you just need to plug them in.
After 2 hours time , both Abe and Gabe to cost the same amount .
<u>Step-by-step explanation:</u>
Here we have , a car needs fixing and Abe can fix it for $70 per hour with a $60 part, but Gabe can fix it for $80 an hour with a $40 part. We need to find How long will it take for both Abe and Gabe to cost the same amount .Let's find out:
Let the time for which both Abe and Gabe to cost the same amount be x hours, so according to question scenario we will have equation as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , After 2 hours time , both Abe and Gabe to cost the same amount .
