Answer:
B = (5, -2)
Step-by-step explanation:
(- 3 + x) / 2 = 1
-3+x = 1*2
x = 2+3
x = 5
(-6+y)/2=-4
-6+y = - 4*2
y = - 8 + 6
y = - 2
Answer: Each pen cost $3.12
Step-by-step explanation:
If you divide 31.20 by 10 you will get 3.12. Each pen costs the same amount so that amount ten times would equal $31.20. To find out how much one pen costs you need solve for only one out of these ten pens which is why you divide.
Here is the graph of x-y=4. According to this, the x intercept is (4,0), and the y intercept is (0,-4) :)
Answer:
There are many choices, but one answer is 2 3.1/5 and 2 3.2/5.
Step-by-step explanation:
These are equivalent to 2 6.2/10 and 2 6.4/10 which is between both.

Answer:
-9, 15
Step-by-step explanation:
Subtract 7 and multiply by 4
1/4 |2x-6| +7 = 13
1/4 |2x -6| = 6
|2x -6| = 24
2x -6 = ± 24
2x = 6 ±24
x = 3 ±12
x = -9, 15
_____
For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.
(1/4 |2x -6| +7) -13 = 0
