I'm assuming that the line is JKL in order of the points from left to right.
JK + KL = JL
(17-x) + (2x-7) = JL
Simplify.
10-x = JL
set up the equation like so
7+15.50x=100
-7 -7
15.50x=93
then divide 93 by 15.50
and youll get 6 as your answer.

Answers:
The first and third options should be selected.
- The ordered pair (10,5) is a solution to the first equation because it makes the first equation true.
- The ordered pair (10,5) is not a solution to the system because it makes at least one of the equations false.
Explanation:
In order for a point to be a solution to a system of equations, it must make both equations true when its x and y values are substituted in. That being said, we need to test if (10,5) is a solution for the two equations.
Let's try the first equation. Substitute 10 for x and 5 for y and solve:
-5 does equal -5, so (10,5) is a solution to the first equation.
Next, let's test the second equation. Do the same:
However, 20 does not equal 11, therefore (10,5) is not a solution to the second equation.
So far, we know that (10,5) is a solution to the first equation, but not the second equation. Knowing this, it cannot be a solution to the system because it does not make both equations true. Therefore, only the first and third options should be selected.
Its most likely D, vertical shift up 1/3, because the slope, 1/3 is positive, so you are moving up 1 and right 3 units.
Answer:
It might help you if you knew what variable was.
A variable can be (x) or (y) or anything really it just a letter the represents a number.
In this case, when it says solve for a variable it means find what the variable equals. For example:
4x + 18 = 2
here you need to find the value of X.
x = -5
X equals negative 5 because you multiply the variable to the number:
4 x -5 = -20
-20 + 18 = 2
making the answer:
4(-5) + 18 = 2
x = -5
(hope this helps)
