The absolute value equation is 
, if the solutions are x=2.5 and x=-3.5.
Step-by-step explanation:
The given is,
Two solutions: x = 2.5 and x = -3.5
Step:1
In this question we use reverse method of quadratic equation solve method,
From first solution, x = 2.5
x - 2.5 = 0..........................(1)
From the second solution, x = -3.5
x + 3.5 = 0.................(2)
From the equations (1) and (2),
( x - 2,5 ) ( x + 3.5 ) = 0
Multiply the equations,
Step:2
Check for solution,
..........................(3)
Substitute the value of x=2.5 in above equation,
6.25 + 2.5 - 8.75 = 0
0 = 0
Result:
The absolute value equation is , if the solutions are x=2.5 and x=-3.5.

Step-by-step explanation:
Answer:
An angle showing a turn through 1/8 of a circle is smaller
Step-by-step explanation:
we know that
A complete circle represent 360°
so
<em>An angle showing a turn through 1/8 of a circle is</em>
<em>An angle showing a turn through 1/3 of a circle is</em>
therefore
An angle showing a turn through 1/8 of a circle is smaller
Answer:
g is the independent variable.
u is the independent variable.
Step-by-step explanation:
According to the question, the data mentioned is as follows
Equation g = 748u
where,
g = the total number of gallons of water used
And, u = the number of units.
As we've seen, Consumers are using the number of units of water.
The volume of water units does not depend on the total quantity of gallons of water that is being used.
So, the number of units i.e u represents an independent variable.
hence,
The value of the total quantity of gallons is entirely dependent on the number of units used, and the g represents the dependent variable
Therefore,
The third and fourth option is correct
Answer:
Step-by-step explanation:
-x + 2y = 8
-2x + y = -5
2x - 4y = -16
-2x + y = -5
-3y = -21
y = 7
-x + 14 = 8
-x = -6
x = 6
(6,7)
