The linear equation that models the cost for having x additional family members added is:
c(x) = $75 + $10.99*x
<h3>
How to get the linear equation?</h3>
Here we know that the plan has a fixed price of $75 plus $10.99 for each family member added beyond the primary account holder.
Then if there are x family members added, the cost will be:
$75 + $10.99*x
Then the linear equation that models the cost for having x additional family members added is:
c(x) = $75 + $10.99*x

The answer to this, maybe.., is 180
Answer:
x = -7
Step-by-step explanation:
The given equation is :
-30=5(x+1)
We need to solve the equation.
Use associative property on RHS.
-30 = 5x+5
Subtract 5 from both the sides.
-30-5 = 5x+5-5
-35 = 5x
x = -7
Hence, the value of x is -7.
Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:

So, here the distance RT = 
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
All the angles are congruent in square and rectangle, rhombus has consecutive angles so we can say that all of them have consecutive angles congruent except the parallelogram.
