Answer:
Inverse variation k=4
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
In this problem
The graph represent a inverse variation
Because
if x increases ----> y decreases
if x decreases ----> y increases
Find the value of k
we have that
For x=2, y=2 -----> see the graph
substitute
An= a1+(r-1)d
Is the formula for an arithmetic function involving D
Answer:
<h3>
C. 2x+3+1/2 (4x+2)+2</h3>
Step-by-step explanation:
This is the answer
The complete question gives the following options:
A) The 7-inch side and the 10-inch side must make a 52° angle.
B) The 7-inch side and the 10-inch side must make the 38° angle.
C) It does not matter whether or not the 7-inch side and the 10-inch side make a 52° angle.
<span> D) It does not matter whether or not the 7-inch side and the 10-inch side make the 38° angle.
According to the SAS rule for triangle congruency, two triangles are congruent if they have congruent two sides and the angle included.
Therefore, the only way to build a triangle congruent to ABC is to say that the given angle is the one included between the two sides.
Therefore, the correct answer is: </span><span>B) The 7-inch side and the 10-inch side must make the 38° angle. </span>
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
