Answer:
The x-intercept is at (2,0).
Step-by-step explanation:
The x-intercept(s) can be found by setting y to 0 and solving for x.
Your equation is:
4x+2y=8.
To find x-intercept replace y with 0:
4x+2(0)=8
4x =8
Divide both sides by 4:
x =2
The x-intercept is at (2,0).
If one sound is 10^x times more intense than another sound, then it has a sound level which is 10*x more decibels than the less intense sound. So, 10*6=60=7.75^2≈60
Answer:
Like terms:

1.25x²
-8x²
Step-by-step explanation:
Like terms are terms that have the same variable to the same exponent. In this case, the only like terms are those with the variable 'x' to the exponent of '2', or x². This would include the terms:

1.25x²
-8x²
The term 5yx², also includes x², however, it also includes the variable 'y' which makes it 'unlike' the other terms.
