Answer:
The slope of the linear equation is 0.1998, and it means that the calories in a beef hot dog is increasing with the rate of 0.1998 calories per milligram of sodium.
Step-by-step explanation:
- Using y = mx + b, we know that m represents the slope.
- Looking at the equation of c = 0.1998s + 76.4520, our m is equal to 0.1998.
- This slope means that the rate is increasing by 0.1998 calories for every milligram of sodium.
Answer:
The answer is -x^4, Good Luck!
Step-by-step explanation:
(3x^4+2x^2-6) - (4x^4+2x^2-6) = -x^4
Your basically building a new equation with the two functions given to you.
(sqrt(3x + 7)) + (sqrt(3x - 7)) = 0
Then just open up the brackets and simplify further.
sqrt(3x + 7) + sqrt(3x - 7)= 0
Nothing to special really happened there, just removed the brackets. Now you move one of the radicals to the other side so you can square the whole equation.
sqrt(3x + 7) = - sqrt(3x - 7)
Then go ahead and square both sides to remove the radical.
3x + 7 = 3x - 7
Now if you kept trying to isolate x, you find that both sides will just cancel each other out and you are left with,
7 = -7
Since that statement isn't true your answer will be that there is no solution to this equation.
x ∈ Ø
