Supplementary angles equal 180 degrees combined. A right angle equals 90 degrees, so in order to equal 180 you need 90 more degrees. The answer is always ☺
Answer:
x = 5
Step-by-step explanation:
2x -4 = 6
Add +4 on both sides
2x = 10
Divide by 2
x = 5
<span>5x + 20 = -5x
5x + 5x = -20
10x = -20
x = -20/10
x = -2</span>
The numerator and denominator must be polynomials so
the answer to your question is - 7x / x^2 ( the last one on the right)
Answer:
8x-14=8x-14
Step-by-step explanation:
So if both the equations are the same, that means that any value of x put in the equation will equal itself, so that means that there are infinite solutions to the equation
If you try to solve this equation, this happens
8x-14=8x-14
add 14 to both sides
8x=8x
divide by 8 both sides
x=x
This means that there are infinite solutions because any number could be x and it would still work
