HELP me. Consider the statement: "The difference between the product of (-15) and (-2) and the sum of (-10) and (+3)".

a) Write a mathematical expression that represents the statement given above.

b) Evaluate the expression from part (a). You MUST show all working.

Consider the function represented by the equation 1/2 j + 1/4 k equals 3 which shows the equation written in function notation with j as the independent variable

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
