Factor the binomial using its gcf: 10x-15x^4

Acompany manufactures three types of cabinets. it makes 110 cabinets each week. in the first week, the sum of the number of type-1 cabinets and twice the number of type-2 cabinets produced was 10 more than the number of type-3 cabinets produced. the next week, the number of type-1 cabinets produced was three times more than in the first week, no type-2 cabinets were produced, and the number of type-3 cabinets produced was the same as in the previous week.

If f(x) = -5x + 1 and g(x) = x3, what is (gºf)(0)? enter the correct answer

What are the solutions for the following system? -2x^2+y=-5 y=-3x^2+5
