Answer:

denotes amount of food that Felicity's dog eats
Step-by-step explanation:
Given:
Felicity's dog eats no more than two cups of dog food per day.
Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats.
The amount of food that Martin's dog eats is represented by using 
To find: the inequality that represents the situation
Solution:
Amount of food that Martin's dog eats = 
Amount of food that Felicity's dog eats ≤ 2
Also,
Amount of food that Felicity's dog eats 
Therefore,
Amount of food that Felicity's dog eats ≤ 2
Let
denotes amount of food that Felicity's dog eats.

Answer:
X = 7.2
Step-by-step explanation:
Hello
For the triangle of right side, using Pytagoras:
(2.5)^2 + b^2 = 6^2
6.25 + b^2 = 36
b^2 = 36 - 6.25
b^2 = 29.75
b = 5.45
Now we can to find X using again Pytagoras:
3^2 + (5.45)^2 = x^2
9 + 29.75 = x^2
38.75 = x^2
X = 7.2

An equation is formed of two equal expressions. The equation of the exponential graph is A=100(0.5)ˣ.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation of an exponential function is given by the formula,
y = A (B)ˣ
Now as per the graph, there are two points (1, 50) and (2, 25).
50 = A (B)¹
50 = AB
A = 50/B
Substitute another point in the equation,.
25 = A (B)²
25 = (50/B) (B)²
25 = 50B
B = 0.5
Substitute the value of B,
A = 50/0.5 = 100
Hence, the equation of the exponential graph is A=100(0.5)ˣ.

Since they are both squared.
Evaluating 5^2 and 2^2 and finding the quotient also works.

The third option, "Evaluate 5^2 and 2^2 ...," and the last option, "Rewrite the expression as (5/2)^2 ...," are the correct choices.
