When I triple my number and add 4 I get 10 what is my number

Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x,y) coordinate plane?
