(Maria has a fence around her triangular garden. The first side is (y+4) feet long. The second side is 2 feet longer than the first side. The third side is three feet less than 2 times the first side. Write a simplified expression to represent the perimeter of her garden.)

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

Suppose you are choosing a 6-digit personal access code. this code is made up of 4 digits chosen from 1 to 9, followed by 2 letters chosen from a to z. any of these digits or letters can be repeated. find the total number of personal access codes that can be formed. 492,804 341,172 39,917,124 4,435,236
