B. Cost of party (c)

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

Really need ! 35 create an equation that can be used to find the value of x? hint: what type of angle pair do you see? here are the questions to answer, after you create an equation: 1) what should be the total amount used for this type of angle pair? explain how you know. 2) what is the answer to your equation for "x"? 3) after you find your answer for "x" in your equation, find the degree measurement for angle aed?
