Answer:
2y - 5y = -3
Step-by-step explanation:
Standard form: Ax + By = c
y + 1 = 2/5(x+4)
y + 1 = 2/5x + 8/5
- 1 -1
y = 2/5x + 3/5
5(y = 2/5x + 3/5)
5y = 2x + 3
-2x -2x
-2x + 5y = 3 (Ax + By = C)
-1(-2x + 5y = 3) (leading coefficient needs to be positive)
2y - 5y = -3
Hope this helps!
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
Depends greatly on the type of function.
Some things to keep in mind:
1.) the value of the denominator of a fraction cannot be zero
2.) the inside of an even root cannot be less than zero
3. The argument of a logarithmic function must be greater than zero
4. Plus many more other rules and such
But a simpler explanation, just find out what values x can be for the given function, and what y can be.
The x values make up the domain, the y, the range
Graphs are helpful

Answer:
$7.58
Step-by-step explanation:
Think about it, (S+C), each flavor costs $3.97 per carton, and there's 2 cartons. $3.79 x 2 = $7.58
