6(a+3) = 18 + 6a
Open the parenthesis and distribute
6a + 18 = 18 + 6a
Subtract both sides by 18
6a = 6a
Subtract both sides by 6a
0 = 0
Any value of "a" will satisfy this equation.
Cos A) 16/20 or 4/5
Tan A) 12/16 or 3/4
Sin A) 12/20 or 3/5

Linear function
<h3>

</h3>
Step-by-step explanation:
<h2>

</h2><h3>Linear function</h3>
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.
<h2>

</h2><h3>Not linear function</h3>
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1
, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

Answer:
300 minutes
Step-by-step explanation:
Let
x----> the numbers of minutes used
y ---> the cost per month
we know that
<em>First cell phone plan</em>
y=0.15x+20 ---> equation A
<em>Second cell phone plan</em>
y=0.10x+35 ---> equation B
equate the equation A and equation B
0.15x+20=0.10x+35
Solve for x
0.15x-0.10x=35-20
0.05x=15
x=15/0.05
x= 300 minutes
Find the cost y
y=0.15(300)+20 =$65
That means
For x=300 minutes
The cost for both calling plans is y=$65
