The right simplified expression is j - 10
Simplified expression is the simplest form of the equation. We need to group the variable before simplifying equations that have different variables, for example :
a + b + a + c + b
it can be simplified as
a + a + b + b + c = 2a + 2b + c
From the question above, we know that :
( j-8)-2
First, group the same variables
j - 8 - 2
= j + (-8 -2)
= j - 10
Hence, the right simplified form is j - 10 .

Answer:
-26
Step-by-step explanation:
To find the slope a line, we need to find the rise over run between two points.
=
=
= -26
The slope is -26
Given:
Basic cost = $45
Cost of long distance calls = $0.10 per minute
To find:
The total cost if you had 45 long distance minutes.
Solution:
Let the total cost be y for x minutes long distance calls.
Cost of long distance calls for one minute = $0.10
Cost of long distance calls for x minute = $0.10x
Total cost = Basic cost + Cost of long distance calls for x minute
Substitute x=45, to find the total cost if you had 45 long distance minutes.
Therefore, the total cost if you had 45 long distance minutes is $49.5.
Answer:
y = (9/5)x - 9.6 in slope intercept (not sure if this counts as reduced?) and y + 6 = 9/5 ( x - 2 ) point slope
Step-by-step explanation:
We need to find the point slope formula. This is y-y1 = m(x-x1). First, we need to find the slope, and we can start to begin to make our equation from there. Slope = rise/run, so 9/5 should be our slope.
y - y1 = 9/5(x - x1) is our new eqn.
Then, we can put one of the points from our line into our eqn, since both pass through our eqn, we can use either point for our calculations.
Sticking with just the first point and substitutuing in values, we get:
y + 6 = 9/5 ( x - 2 ) and now we have to simplify.
y = 9x/5 - 18/5 - 6
y = 9x/5 - (15/5 + 3/5) - 6
y = 9x/5 -3.6-6
y = 9x/5 -9.6
