A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $40 million after 4 years, as shown in the graph: There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 1, negative 50 and 4, 40.

Which equation most closely represents the line depicted in the graph?

f(x) = −30x + 80
f(x) = −40x + 4
f(x) = 40x − 4
f(x) = 30x − 80

Plzzz i beg u so much asaaaap ! what is the slope of this line? enter your answer in the box.

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

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
