Four rectangles are shown in the diagram. for which pair of rectangles is the ratio of the side lengths 1: 3?

What are the coordinates of the hole in the graph of the function f(x) ? f(x)=x2−9x−3 enter your answer in the boxes.

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
