4. simplify. a) 5(2x + 3y) - 4(3x - 5y) b) x - 2(x + 3y) - (2x + 3y) - 4(x + y) c) 3(a + 2b - 2) - 2(2a - 5b - 1)

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')

What term makes it inconsistent y=2x - 4
