Answer:
this is the correct answer for plato (Roger should make 10 fire trucks and 15 dolls in order to minimize the time spent making toys.)
Step-by-step explanation:
We see that both equations have 4y in them. Subtracting the second equation from the first equation, we get (3x -2x) + (4y-4y) = 2 - 8, x = -6
Plugging x = -6 into any equation, we see that our answer is 18 + 4y = 2, 4y = 2 - 18 = -16, y = -4.
Our answer is x = -6, y = -4
Answer:
Equation 3: y = 12x + 17
Step-by-step explanation:
Only a linear equation (degree 1) will have a graph that is a straight line.
- Equation 1: degree 2
- Equation 2: degree 5
- Equation 3: degree 1
- Equation 4: degree 4
The degree of the equation is the highest power of any of the variables. If different variables are in the same term, it is the sum of the powers of those variables.
Answer:
D
Step-by-step explanation:
2x(x^4 + 6x^2 - 27)
x^4 + 6x^2 - 27 = 0
x^2 = y
y^2+ 6y - 27 = 0
(y+9)(y-3) = 0
(x^2+9)(x^2-3) = 0
2x(x^2-3)(x^2+9)
