In a system of linear equations, one equation has a slope of 5 and the other equation has a slope of −5.

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

What is the upper quartile in the box plot?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
