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

Step-by-step explanation:
Average Rate of Change: 
Step 1: Define variables
f(b) = 5
f(a) = 3
b = 2
a = 1
Step 2: Plug into formula
(5 - 3)/(2 - 1)
2/1

Answer:
-3/5
Step-by-step explanation:
the customary way to determine the slope of a linear equation such as this one is to solve the equation for y:
-3x-5y=15 becomes -5y = 15 + 3x after 3x is added to both sides of the original equation.
Solving both sides of this latest result by -5 results in
y = -3 - (3/5)x
The coefficient of x (which here is 3/5) is the slope of this equation.
Answer:
the slope is -1
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-3)-6/5-(-4)
m=-9/9
m=-1
