Answer:
Step-by-step explanation:
This is a system of inequalities problem. We first need to determine the expression for each phone plan.
Plan A charges $15 whether you use any minutes of long distance or not; if you use long distance you're paying $.09 per minute. The expression for that plan is
.09x + 15
Plan B charges $12 whether you use any minutes of long distance or not; if you use long distance you're paying $.15 per minute. The expression for that plan is
.15x + 12
We are asked to determine how many minutes of long distance calls in a month, x, that make plan A the better deal (meaning costs less). If we want plan A to cost less than plan B, the inequality looks like this:
.09x + 15 < .15x + 12 and "solve" for x:
3 < .06x so
50 < x or x > 50
For plan A to be the better plan, you need to talk at least 50 minutes long distance per month. Any number of minutes less than 50 makes plan B the cheaper one.

Step-by-step explanation:
Hello!
To solve for x, we have to first isolate the variable.
<h3>Solve for x</h3>
The value of x is 
.
Step-by-step explanation:
Make a table to find the values of x
P.s pick random y value
When x is 1,
y is 4........ Plug 1 into the equation ur given u get the value of y. So, 2(1)+2
When x is 2,
y is 6......... Plug 2 into the equation ur given u get the value of y. So, 2(2)+2
So this point is (2,6)
When x is 3
y is 8 ......2(3)+2
So this point is (3,8)
When x is 4
y is 10.... 2(10)+2
So this point is (4,10)
Hope this helps
The answer is 43 because when you multiply 6x6 you get 36 and if you add 6 more you get 42 which is one less that 43
