Answer:
8=2x+8
8-8=2x
0=2x
0/2=x
0=x
Step-by-step explanation:
Hope it helps u!!
It’s not a function because the domain (the X) is repeating...
X cannot repeat if you want it to be a function
Given that:
The average cost of a year in college varies from $6000 to $20,000 depending on which college you attend.
To find:
The absolute value equation the could someone use to find the highest and lowest cost of a year in college.
Step-by-step explanation:
Let the average cost of a year in college be x.
The average cost of a year in college varies from $6000 to $20,000.
Average of 6000 and 20000 is
Subtract average of 6000 and 20000 from each side.
Therefore, the required absolute value equation is .
(x + 8)(x - 5)
= x (x - 5) + 8(x - 5)
= x² - 5x + 8x - 40
= <u>x²</u><u> </u><u>+</u><u> </u><u>3</u><u>x</u><u> </u><u>-</u><u> </u><u>4</u><u>0</u><u> </u><u>(</u><u>a)</u>
Answer:
Option D
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by elimination
Multiply both sides equation A by -1
-----> equation C
Adds equation C and equation B
<em>Find the value of x</em>
substitute the value of y in either equation
The solution is the point (-1,2)
In this problem Option A,B and C are correct
The option D not result in a system with a pair of opposite terms
because
Multiply both sides of equation B by -3
-----> equation C
Multiply both sides of equation A by 5
----> equation D
so
equation C and equation D not have a pair of opposite terms
